World of Warcraft®

Whenever a damaging attack brings you below 30% health, your maximum health is increased by 25% for 10 sec, and your threat level towards the attacker is reduced. This effect cannot occur more often than once every 30 sec.

When you deal direct damage or healing for the next 10 sec, 40% of damage or 60% of healing is copied as healing to up to 3 nearby injured party or raid members.
