Triggers: Megas & Primals

Section 4.A.6

These are keys which trigger upon a battler utilizing Mega Evolution or Primal Reversion.

• "BeforeMegaEvolution" Triggers when a battler is going to Mega Evolve this turn, but before that Pokemon actually Mega Evolves.

• "AfterMegaEvolution" Triggers after a battler successfully Mega Evolves.

• "BeforePrimalReversion" Triggers when a battler is going to Primal Revert, but before that Pokemon actually undergoes Primal Reversion.

• "AfterPrimalReversion" Triggers when a battler successfully completes its Primal Reversion.

Trigger Extensions: You may extend these keys with a species ID or a type ID to specify that they should only trigger when Mega Evolving or Primal Reverting a specific species, or species of a specific type. For example, "BeforeMegaEvolution_MAWILE" would trigger only when a Mawile is about to Mega Evolve, where "AfterPrimalReversion_WATER" would trigger only after a Water-type has Primal Reverted.
