Outside of battle
Prior to Generation IX, if a Pokémon with Illuminate is in the first place in the party (even if fainted), the wild Pokémon encounter rate increases by 100%. It shares this trait with Arena Trap and No Guard.
Prior to Pokémon Super Mystery Dungeon, a Pokémon with Illuminate "blinks" after a turn in which it was damaged. The "blink" summons a hostile Pokémon somewhere on the floor.
In Pokémon Super Mystery Dungeon, the Pokémon obtains the Decoy status after using an illuminating move. The Decoy status makes enemies preferentially attack the Pokémon instead of other allies.
