Five Feats (Part III)

There are never enough feats, (expecially if you use the BoXM feat rules). This is the third article of 5 feats a week, from OGC sources, converting them to AE and editing the feats in an attempt to improve balance and avoid "feats that suck", the idea being "why take this feat when I can take power attack?

WILD BIRTHRIGHT [Talent]
You have a preternatural connection with nature.
Prerequisites: 1st level character, Wis 13.
Benefit: Select any three 0-level spells or diminished 1st level spells. You may cast these spells as spell-like abilities once per day, with a caster level equal to your character level. In addition, you gain a +1 bonus on Knowledge (nature) and Survival checks.

WARDED FROM THE DARK [Ceremonial]
Your spirit is strongly attached to your body, making you resilient to energy draining attacks.
Prerequisite: Truename, Con 13.
Benefit: When you gain a negative level, you may immediately make a Fortitude save to shrug off the effects. If you fail the initial save, you may attempt a second save in 24 hours at a +4 bonus.
Undead that use enervating attacks that bestow negative levels gain only half the normal number of temporary hit points when attacking you (rounded down). As well, you can never be affected by an undead creature’s create spawn ability.
Normal: When you gain a negative level, you make a Fortitude save after 24 hours to determine whether the negative level results in permanent level loss.

EXPLOIT OPENING [General]
You take advantages of combat opportunities when they present themselves.
Prerequisites: Combat Reflexes, base attack bonus +6.
Benefit: On the first attack of opportunity you make in any round, you deal an additional +1d6 points of damage.

You are particularly tough and difficult to kill
Prerequisites: Truename, Con 13, Sturdy. +2 Base Attack Bonus
Benefit: You possess a number of bonus hit points equal to your character level + your
Constitution score + your Constitution modifier.
You do not start dying until you reach your Constitution score in negative hit points, and you do no die until reaching a number of negative hitpoints equal to your character level + double your constitution score + your Consitution modifer

TOTEM ASPECT [Ceremonial]
You may assume the characteristics of your animal companion.
Prerequisites: Truename, Animal companion, ability to assume totem shape.
Benefit: By expending a use of your totem shape ability, you can gain the physical benefits (Str, Dex, Con, Natural Armor) bestowed by your animal companion for a number of rounds equal to your totem level. The nature of the benefits depends on your effective level (as per the benefits normally gained by your animal companion).
If you have taken an alternative animal companion, your effective level is reduced by the appropriate amount.
If you have multiple companions from different classes, your effective level is based on your most powerful animal companion.
