"While Avenging Wrath is active, you are healed for 1% of your maximum health every 4 sec."
Tips & tricks
Nothing is as devastating as running away with a few hundred health only to be tagged with a paladin's Hammer from long range. Paladins may make full use of the Hammer on fleeing targets, as well as mobs and bosses who are in their death throes.
There is no minimum range on the Hammer; it can be used at point-blank distance.
The attack is resolved as a ranged special-attack that does non-physical damage, similar to a Hunter's Arcane Shot. It can miss, it can be blocked (if the target is facing you), and it does double damage on a crit. Hit Rating and Crit Rating improve your chances of hitting and critting, respectively.
