Extends the duration of the Ground Zone when the zone turns into a Ground Zone while the user is on the field.
Ground Zone Extension (Japanese: だいちゾーン時間延長Ground Zone Time Extension) is a family of skills in Pokémon Masters EX.
Effect
The duration of a GroundZone active on the field of play will be extended when a sync pair with this skill is on the battlefield. Higher numbered skills will extend the duration of the Ground Zone further. The duration is extended by approximately 10 seconds per skill rank. The extension stacks additively, so having two sync pairs with Ground Zone Extension 5 on the field will extend the duration of the zone by approximately 100 seconds.
