Construct Exemplar

Construct Exemplar is a new feat that requires Improved Construct Essence, and may be taken starting at level 21. It grants the following:
 * You are now considered a Living Construct instead of your original race
 * 100% base healing from Repair spells and 100% damage from Rust
 * Immunity to Sleep, Hold Person, Energy Drain, Nasueated, Exhausted, and Paralyzed effects except those which physically hold you in place
 * Immunity to ability score damage from natural poisons and natural diseases (but are vulnerable to those that specifically affect wood or metal)
 * +10 Racial bonus to saving throws against magical poisons, and do not fail saving throws against them on a roll of a natural 1 (this renders you immune to magical poisons with a DC of less than 11+your Fortitude save)
 * You may remain underwater indefinitely without the need to breathe.
 * When resting at a Rest Shrine, the health you regain is now based on your Repair skill instead of your Heal skill.
