Does Turn Resistance from different sources stack?
Typed bonuses do not stack, however, turn resistance doesn't specify a type. So, if an undead gets a multiple bonuses to turn resistance do they stack or overlap?
The only reference I've been able to find is the feat: Improved Turn Resistance which specifically states that it stacks. No other sources I've seen state the type of bonus or how it interacts with other bonuses.
I'm surprised this hasn't been asked already (unless it was embedded in another question so I didn't see it)
