This Ability effect may be in need of research. Reason:Interaction with multi-turn moves and consecutively executed moves You can discuss this on the talk page.
When another Pokémon (including an ally) uses a move targeting a Pokémon that has Pressure, when PP is deducted from that move, one more PP than usual is deducted. If multiple targets have Pressure, each one results in additional PP being deducted.
Pressure deducts additional PP whenever PP would normally be deducted; this means that it still applies even if the move misses, has multiple targets, or is rendered ineffective due to immunity.
Pressure applies to moves that target the entire field, such as Rain Dance.
If a Pokémon that has Pressure is sent into battle, the message "<name> is exerting its Pressure!" is displayed.
From Pokémon Emerald onwards, if a Pokémon with Pressure is in the first place in the party (even if fainted), there's a 50% chance that a Pokémon will be forced to the upper bound of their encounter level range. It shares this effect with Hustle and Vital Spirit.
