Zen Mode is an Ability. It is the signature Ability of Allerglen and allows it to change form.
When Allerglen's HP drops to below half, it will change into its Zen Mode at the end of the turn, which is a dual-type Poison/Flying form. If it loses its Ability, or recovers HP to above half while in its Zen Mode, it will change back to its Standard Mode. Allerglen will revert back to Standard Mode outside of battle and enters battle in Standard Mode, even if its HP is below half.
Outside of Battle
Zen Mode has no effect outside of battle.
