Avatar of Humility [Exalted, Epic]
You can dodge spells with ease, and are even less affected by fire and cold.
Prerequisite: Master of Humility, Con 19, character level 15, can own only what she can carry, must give 10% of income to charity, can not own more than 6 magic items (this doesn’t includes items with charges or one time items such as potions or scrolls)
Benefit: A Character with this feat gains fire and cold resistance 30, does not needs to eat or breathe, can now apply Improved Evasion to her will saving throws. A Ranger with this ability gains 2 extra hit points per level, the effect is retroactive and cumulative with the benefits from Master of Humility. A Paladin with this feat gains a +2 sacred bonus on saving throws. This stacks with the bonus from Acolyte of Humility.
