Usage
When combined with Empathy or Spiteful Spirit, this skill is a very effective means of damaging enemies who rely on attacks. However, it should be noted that while Empathy and Spiteful Spirit trigger whether the hexed foe connects or not, this skill only drains health when the target actually hits, not when their attack misses or is blocked or evaded.

If a target is attacking you, this skill is an extremely effective way of reducing the damage taken. Because you are healed every time they attack, their attack essentially does that much less damage to you, and hurts them in the process. Coupled with Enfeeble, a target's damage may be less than the health provided, healing you with each successful attack.

A good PvP and/or PvE build is an addition of Price of Failure, Spiteful Spirit, and Insidious Parasite. While attacking, the opponent will miss occasionally (Price of Failure), take damage when they miss (Price of Failure), take damage when they hit and also heal you (Insidious Parasite), and take damage for just swinging at you, regardless of hit or miss (Spiteful Spirit). This combo is a warrior's bane.
