|The user attacks the target with a bursting flame. The bursting flame damages Pokémon next to the target as well.|
Flame Burst deals damage to the target, then inflicts damage to all Pokémon that are both adjacent to and allied with the attack target equal to 1/16 of their respective maximum HP. The adjacent Pokémon will not take damage if the attack target takes no damage (such as due to Flame Burst missing, Flash Fire, or the target being protected).
The secondary damage is indirect damage, so it will not trigger Abilities like Flash Fire or Color Change. Furthermore, being effect damage, it is prevented by Magic Guard, but it bypasses protection moves and Endure, Wonder Guard, Substitute, Destiny Bond, and Telepathy. This damage cannot miss.
