The wardens are the foremost protectors of frost hawk expeditions. Their resilient mentors teach them the sagas of their ancestors, and watch over their expedition teams with care and warmth.

Tundra Kept (Su)
The frost hawk warden adds his doctrine bonus on weapon damage rolls, regardless of his alignment. This additional damage is cold damage.
This modifies doctrine

Story Keeper (Su)
A frost hawk warden’s mentor uses the heroic legends of old to instruct him in the ways of his alignment. A frost hawk warden learns the saga of a single Frost Hawk Legend at 3rd level. A frost hawk can spend a free action to allow himself or his mentor to embody a frost hawk legend he knows for a number of rounds equal to 1/2 his level (minimum 1). Doing so reduces his doctrine bonus by 1 for 24 hours.
This replaces pure paragon

Flame in the Cold (Sp)
At 4th level, a frost hawk warden and his mentor protect their allies as a flame in the cold. Allies within 10 feet of the frost hawk warder or his mentor are protected from cold environments (as per endure elements).
This replaces the belief gained at 4th level

Instant Lore (Su)
At 19th level, the frost hawk warden can reduce his doctrine bonus by 1 in order to learn the saga of a single frost hawk legend. This reduction and new knowledge both last for 24 hours.
This replaces greater purity
