Gym (GO): Difference between revisions

A Gym (Japanese: ジム Gym) is a type of location in Pokémon GO.

In the Map View, Gyms are marked as color-coded towers with the Gym symbol above them. If the Gym belongs to a team, the top of the tower will swap between the Gym symbol and the Gym's newest added Pokémon.

Placement

A Gym claimed by Team Valor, with a Metagross as its newest addition

Gyms are fixed locations in the real world that players must physically visit to battle. Gyms are generally in public locations, including (but not limited to) public artwork/murals, libraries, famous landmarks, churches, police stations, fire stations, and public parks. While players must be physically close to Gyms to battle them, they generally do not need to enter the building to be close enough (if the Gym is a building).

Gyms are based on a selection of portals from the Niantic game Ingress. Until 2015, Ingress players could submit proposals for portals which subsequently had to be approved by Niantic. Gyms are less common than PokéStops, which were also created from Ingress portals. This distribution was slightly balanced, after some PokéStops were converted into Gyms on June 19, 2017.

If for some reason a physical location is unsuitable as a Gym, players may send a request to Niantic via the Pokémon GO website or Niantic Support official Twitter account to remove it from the game. This could be due to safety concerns or if there is an error related to the Gym (the landmark no longer exists, never existed in the first place, or has been converted to a different use such as a private residence). It should be noted that this is considered more than a simple movement of the stop with the old one removed from the game and the new position being considered a new PokéStop. As a result, any active Exclusive Raid invitations are revoked.

Inspecting a Gym

If a Gym tower is visible in the Map View, it can still be inspected even if it is outside of range.

If the player is not on a team and below level 5, they will be advised to return at level 5. Once they are at least level 5, they will be given the option to select a team. Once the player selects a team, it cannot be changed without submitting a request to Nianti

If the player is on a team, they can view the Gym screen, which shows the location's name and photo in the top-left corner and any Pokémon defending it. When a defending Pokémon is selected, the following information will be displayed:

• Pokémon name (or nickname if owned by the player)
• Hologram of Trainer's avatar with name and Trainer level
• Total time defending
• Number of Berries (treats) fed to
• Number of battles when defending

If the Gym is of the player's team, they may feed Berries to defending Pokémon to increase their Motivation and CP, and if there are less than six Pokémon already defending it, they may deploy a Pokémon at full health to defend the Gym.

Obtainable items

Like with PokéStops, a player can collect items and/or Eggs from Gyms by tapping on the PokéStop icon in the bottom right corner, and then spin the Gym's Photo Disc while within range. This will cause two to three items and/or Eggs to appear in bubbles that emerge from the Photo Disc. While it is possible to tap the bubbles to collect their contents, they will be collected regardless. In addition, searching a Gym gives random amount of experience.

Once the player has searched a Gym's photo disc, it will turn purple for that player only for five minutes. The player cannot search a purple photo disc until it turns into the Gym's color again. The items that searching a Gym can yield are dependent on the player's level, with certain items not being unlocked until later levels. Searching a Gym will not yield Eggs if the player already has the maximum nine Eggs. A player will get only one Raid Pass a day and is guaranteed to drop as long as the player doesn't have one already in their possession. Multiple of the same item can be obtained from a single search. Searching a Gym for the first time will yield a Gym Badge.

Gym Badges

The first time a player visits a Gym and spins its Photo Disc, they will receive a Gym Badge for that Gym. All subsequent actions taken at that Gym - stationing a defending Pokémon, participating in a Raid Battle, using the Pokéstop or battling a Pokémon - will reward the player Badge Experience to level up the Gym Badge through Bronze, Silver, and Gold levels. Each additional level of the Gym Badge rewards the player an additional item when using the Pokéstop at that Gym and an additional 25 Trainer XP (before team bonuses are factored in). Items obtained as a Badge bonus will be shown in a yellow bubble.

Badge	Min. Badge XP	Trainer XP		Bonus items
		Rival	Friendly
	0 XP	25 XP	31 XP	+0
	500 XP	50 XP	63 XP	+1
	4,000 XP	75 XP	94 XP	+2
	30,000 XP	100 XP	125 XP	+3

Earning Badge experience

Players can earn Badge experience the following ways:

Control

If a Gym tower is white, that Gym is currently not controlled by any team. If in range of the Gym, a player on a team can claim it for their team by placing one of their own Pokémon in it.

If a Gym tower is red, yellow, or blue, that Gym is currently controlled by the team of that color and the newest defending Pokémon in the Gym will appear on top of the tower marking the Gym. A Gym can house up to 6 defenders and if a player of the defending team is in range of the Gym and there is room for another defender in the Gym can add one of their own Pokémon to defend the Gym. Only Pokémon with full HP can be deposited in a Gym as a defender. Buddy Pokémon also cannot be placed in a Gym. While in a Gym, Pokémon cannot be evolved, Powered Up, traded, or used for battle at another gym.

Trainers on opposing teams will be prompted to challenge the Gym to lower opposing Pokémon's motivation and attempt to defeat the defending teams Pokémon.

When a Pokémon loses a battle, its motivation goes down which is linked to its CP, this makes the Pokémon weaker and easier to take down. When its CP reaches 0, the Pokémon returns to its trainer with restored CP and a PokéCoin defender bonus (one for every ten minutes defending).

A player can also restore the motivation and the CP of Pokémon in a Gym that is occupied by their Team by feeding them berries. When in range, the effect of these berries in restoring CP is greater. However, the more berries fed to a Pokémon by the same trainer, the smaller the recovery in motivation, and as such CP. Feeding a Nanab Berry has greater effect in raising motivation and CP than Pinap Berries or Razz Berries. Feeding a Pokémon a Golden Razz Berry will fully recover a Pokémon's motivation and CP. A player can feed up to ten Pokémon with up to ten berries each in a 30 minute period. Feeding a Berry rewards the player with 20 Stardust, 20 XP, and a chance of obtaining a Candy of the Pokémon that the player is feeding. Feeding berries also contributes to the "Berry Master" Medal.

Defender bonus

When the defending Pokémon returns from Gym to its trainer, it brings a defender bonus in the form of PokéCoins. This is the only way to obtain PokéCoins without buying them with real money.

The player receives 1 per 10 minutes defended, capped at 50 per day (achieved by defending for 8 hours and 20 minutes). Daily limits on defender bonuses are counted on the day the Pokémon was knocked out of the Gym. If a Pokémon was placed in a Gym on Monday and returned the following Tuesday, the PokéCoins earned will count towards Tuesday's daily limit. If the Pokémon were to return on Wednesday instead, its defender bonus will count towards Wednesday and will not receive any for Tuesday.

Gym Battles

A Pokémon battle at a Gym

In Pokémon GO, battles can be conducted at Gyms between Trainers on opposing teams. Battles are not turn-based, and they are conducted between a player and a computer-controlled opponent and have a time limit of 100 seconds per defender. Defending Pokémon are battled in sequence, from the oldest defender to the newest.

When battling a gym, the player selects a team of six Pokémon of their own to battle against the defending Pokémon. Each defending Pokémon defeated will award XP to both the player and their associated Gym's badge. Defeating only one defending Pokémon counts as a victory towards earning medals and completing certain Field Research tasks, regardless of how many of the player's Pokémon fainted.

Whenever a Pokémon is placed into a Gym to defend it, it will have a heart-shaped gauge that measures its motivation, which is used to determine the defender's CP in battle. A Pokémon at 100% motivation will have 100% of its total CP when challenged. Initially, a Pokémon placed into a Gym will have about 92% motivation.

Battling at a Gym decreases a defending Pokémon's motivation (and CP) for future battles, by about 28%, making it easier to defeat next time it's battled. Once an opposing Pokémon's motivation is reduced to zero, it is knocked out of the Gym and return to their Trainer with zero HP. If a defending Pokémon is victorious, the timer expires, or the challenger flees, the defender will still lose a small percentage of its total motivation (about 1.6%).

After defeating a Pokémon, the player has ten seconds to decide if they want to battle the next defender. They can also leave it and the battle will end, but it won't be considered as a player's defeat. If the player chooses to re-battle again, they will again start by battling the first defender in the lineup.

During Gym battles, the player's Pokémon will take damage, lowering their HP and potentially causing them to faint. Battle-damaged Pokémon can have their HP and consciousness restored with healing items, such as Revives and Potions.

Players can work together to challenge, with the defending Pokémon's HP being shared between players. An icon with a number will appear underneath the countdown timer of the screen indicating the number of players currently fighting that Gym. Up to 20 trainers can battle together. Challengers who have high friendship levels with each other will deal extra damage per attack.

Battle mechanics

Battles are shown with the Gym's Pokémon at the middle of a circular arena with the attacking Pokémon at the circle's edge.

Each Pokémon has three stats which are relevant to Pokémon battles: HP, Attack, and Defense. A Pokémon's Combat Power (CP) is derived from those three stats. A Pokémon loses HP when it is hit by attacks, and faints when its HP is depleted. Damage dealt by attacks is mostly determined by the user's Attack stat, the target's Defense stat, and the attack's power.

Additionally, special type effectiveness rules apply in Pokémon GO; type effectiveness is derived from the type chart in the Generation VI core series games, but there are no immunities and different multipliers. The same-type attack bonus is applied, giving a 20% boost to moves of the same type as the user.

During a battle, the player can forfeit or switch Pokémon by tapping the buttons at the bottom-right of the screen. Forfeiting counts as a loss, but the number of Pokémon defeated before forfeiting determines the change in their motivation.

Combat actions

During battle, a Pokémon can perform one of three basic actions.

• Dodge: swipe left or right on the screen.
• Fast Attack: tap the screen.
• Charged Attack: tap the Charged Attack button. This can only be used when the Charged Attack meter is sufficiently charged to execute at least one Charged Attack.

Every Pokémon has one Fast Attack and at least one Charged Attack, being based on moves the Pokémon can learn in the core series games. Most Pokémon can learn a second Charged Attack by using the "New Attack" feature. Charged Attacks are normally more powerful than Fast Attacks and require charging before use.

Dodging

When a Pokémon is about to use an attack, swiping to the left or right can cause the player's Pokémon to dodge the attack for 0.5 seconds. A successfully dodged attack, performed within an attack's damage window, will deal 75% less damage.

Fast Attacks

The challenging Pokémon can use a Fast Attack at any time during a battle simply by tapping the screen. Using a Fast Attack charges up energy for Charged Attacks.

Charged Attacks

Using a Charged Attack requires consuming one bar of the energy meter. There is also a wind-up period between commanding the Charged Attack and executing it, usually longer than that of a Fast Attack, leaving the Pokémon open to enemy attacks.

The energy meter is empty when the Pokémon is sent out (even if it previously battled but was switched out), and is filled by using Fast Attacks or taking damage from the opponent. If the Pokémon is remaining active after it was just victorious in the previous battle, the Charged Attack meter is retained. The energy meter is displayed at the bottom of the screen below the button which activates the Charged Attack.

The amount of energy required by a Charged Attack depends on the number of bar segments for that move (visible on the status screen). Charged Attacks with more bar segments use less energy for a single use, so can be used more frequently than Charged Attacks with fewer bar segments. Typically, Charged Attacks with higher power require more energy per use. Consequently, weaker Charged Attacks can typically be used more frequently than stronger ones.

Previously, Charged Attacks appeared in the top right of the screen below a Pokémon's HP and was activated by holding down on the screen.

Raid Battles

A Raid Pass

Main article: Raid Battle

Raid Battles can also take place at Gyms. A wild Pokémon, typically one much stronger than can be found in the wild, will be stationed at the Gym for a period of time. Using a Raid Pass players can challenge the wild Pokémon and fight it as though it were a Gym defender.

EX Raids are exclusive raids given out by invitation only to players that have raided at a gym at some point in the previous week. They allow the player to battle against Legendary or Mythical Pokémon that may be otherwise difficult to obtain.

Gym System updates

This section is incomplete. Please feel free to edit this section to add missing information and complete it. Reason: more information on updates

There have been many updates introduced to the Gym system since the game's implementation, mostly related to the players quality of life. Various changes include moving the Charged Attack gauge and changing the execution from a long press on the screen to a button, moving around the other elements of the UI, and adding a small battle log to the bottom right delivering players information regarding move effectiveness.

Early Gym system

Main article: Prestige

When the game first released the Gym system was very different. Each Gym was capable of having ten defenders, and there was no limit on the species of Pokémon defending. They were ordered with the lowest CP Pokémon at the bottom, going up in rank to the highest CP. Instead of motivation Pokémon had prestige, and players of the defending team could train at the Gym to increase this value and make it harder for opposing teams to defeat the Pokémon and ergo the Gym. Furthermore, the defender bonus was determined by the amount of Pokémon you had in Gyms, for a collection of a hundred PokéCoins a day.

This caused a lot of stagnation and power imbalances early on in Gyms during the release of the game as weaker players had issues taking down Gyms with especially powerful Pokémon defending them. It was significantly more time consuming and difficult to defeat Gyms as Pokémon never lost CP and only lost Prestige as they were defeated. Players that had positions in ten Gyms had no reason to take down other Gyms rather than maintain their positions in the current Gyms as Gym Badges weren't yet implemented. Additionally, if your Pokémon was at the top of a level ten Gym, a players position was fairly secure as attackers would have to battle their way through the previous nine Pokémon before being able to fight the top position. It created a situation of the strong getting stronger, with the weak being unable to catch up, due to the "free" in-game currency and the bonuses one could buy with it (such as incubators and bag space) and extra Stardust which allowed them to strengthen their Pokémon.

The new system improved on all of this by introducing the motivation mechanic, limiting species within a Gym, lowering the amount of Pokémon defending a Gym, and only rewarding PokéCoins once a Pokémon was returned to its player.
