Lampent puts its arms together and a light blue and blue flame appear in between its hands. It then pulls its arms next to it, dragging the fire with it. It then leans on its back and throws the fire to the top of its head. When the fire reaches its head, Lampent starts to spin rapidly with the top of its head facing the opponent. A light blue stream of fire with dark blue rings of fire around it then fires from the top of its head at the opponent.
The purple flame on the top of Litwick's head stretches out into the sky. Then, an orb of light blue and blue fire forms in front of Litwick's flame. Litwick then fires a spiraling stream of light blue fire with rings of dark blue fire from the orb at the opponent.
Inferno is the only non-status move that has a 100% chance of burning the target under normal conditions. The only other move with the same possibility is Fling, but in its case, burn is only achieved if the user is holding a Flame Orb.
