Endure
Summary
Prevents direct damage from lowering the user's health below 1% this action.
Description
The user braces itself and focuses solely on surviving the next attack no matter what. While using this, the user glows a blueish color. If struck by a move while Endure is being performed, the user will consume a fair amount of energy to hang on and survive the attack, taking reduced damage (and never falling below 1% HP). Enduring multiple attacks becomes increasingly difficult, and the move may eventually fail. In addition, Endure does not allow for the survival of non-attack damage from environmental conditions such as Sandstorm, status effects such as burn, and similar.
Endure costs a base 2% energy (deducted if the attack is used, even if it doesn't end up blocking anything), plus an additional 1/3 the damage that would have reduced the user of Endure to below 1% health but which was instead prevented. For example, if a Pokémon at 3% health uses Endure, then is struck by an attack that would deal it 8% damage, the Endure prevents 6% of that damage and costs 4% energy.
