Brute Strength, Invincible (Feat)
Your muscles and sinews crackle horrendously as you exert your might far, far beyond any mortal limits of strength.
Prerequisites: Level 33, Brute Strength (Feat), or, Barbarian level 25
Benefit: Add your Constitution score to your Strength score to calculate your lifting and carrying capacity, as well as your Str checks for breaking obstacles.
For example, if a character has a 28 Str and a 30 Con, this feat allows you to calculate your Str as if it were a 58, namely, giving a Light load capacity of 25,600 pounds, +24 on Str checks, etc. The effects of this feat stack with Brute Strength, but do not provide any additional damage or chance to-hit.
Note that ability drains and damage are still assessed against both Str and Con as normal, and reducing both Str and Con will lower your effective Str for all purposes.
Special: Only your permanent Con modifier from Stat bonuses may be used for this feat: Temporary stat bonuses from rage, channeling feats, or any other non-permanent sources such as spells may not be used.
Special: Barbarians who take this feat gain its benefits in addition to their normal bonuses for calculating carrying capacity (i.e. add their CON again when calculating carrying capacity).
