Next time you would die, you will instead survive with 1hp left, the next hit prediction box will state "Barely Alive" instead of "Death" when Death Protection is about to be consumed.
Your next monster kill will grant 50% more XP, consumed even by killing a No Experience enemy, granting 0 bonus XP.
Applies the Poisoned debuff on the target.
The poisoned target doesn't regain hp or mana upon exploration, attacking a monster heals all the monsters of any poisoned status. You can freely cast spells on them tho.
