The target endures any attack with at least 1 HP. Its chance of failing rises if it is used in succession.
Effect
this move has a 200% chance for the following additional effects to occur:
For the rest of this round, if the user's HP would be reduced to less than 1 by a non-user's attack, that attack's damage is changed so that it reduces the user's HP to 1 instead. Will stop a multi-hit move once the user's HP reaches 1. Fails if this is the last attack to be used this round. A variable X starts at 1, and resets to 1 if this move fails, or if the user uses a move that isn't Detect, Endure, King's Shield, Protect, Quick Guard, Spiky Shield or Wide Guard. This move has a 1/X chance of succeeding. X is doubled each time this move is successful.
