Prior to Update 21, this ability had a percentage-based Health bonus rather than flat values, and also gave resistance and immunity to Poison Damage. This update removed the Poison resistance and immunity, but increased the Disease resistance.
In Update 29, immunity to the Diseased status effect was removed, and Poison resistance was returned to this skill.
Gain 9% Max Health and 1485 Poison and Disease Resistance → Increases your Max Health by 1000 and your Disease Resistance by 2310. You are immune to the Diseased status effect.
