Guillotine is an offensive Normal-type move; it is a One-Hit K.O. move that deals damage equal to the target's current HP.
Despite having an accuracy of 30% listed, the accuracy of this move is calculated using the following formula: ((level of user - level of target) + 30)%
This formula means that the accuracy starts at 30% when the Pokémon have the same level, and is 1% more likely to hit for every level the user is higher than the target. If the user is at least 70 levels higher than the target, Guillotine will always hit. If the user is a lower level than the target or has the Sturdy ability, the move always fails.
This chance of hitting is not an accuracy: it is not affected by accuracy and evasion stats, nor is it affected by other accuracy modifiers such as Gravity, Wide Lens, and Compound Eyes. Additionally, Guillotine cannot hit a semi-invulnerable Pokémon. However, effects that guarantee moves to hit (such as Mind Reader and Lock-On) still affect Guillotine.
Guillotine will break a Substitute if it hits.
