Bear Shaman Totem Transformation

[dmovrich]

If I choose Bear's toughness (+2 natural armor bonus to AC, Endurance feat) for my transformation ability, is the Endurance feat only active for the few minutes I activate the transformation?

Regardless of the answer, once I advance to the next level, could I take the diehard feat? (having the Endurance feat is sole prerequisite)

The benefits of the ability only last as long as the ability lasts. A permissive GM might allow you to take it, but the feat would be inoperable except when you activate the Bear's Toughness ability and gain the prerequisite feat. Most GMs would not allow you to take it.
