I am currently mocking up a Goliath Barbarian, and was wondering if there is a limit to the amount of sources of "You count as if you were one size larger for the purpose of determining your carrying capacity" that stack.
From prior browsing, I've found that Goliath's Powerful Build & Totem Barbarian's Bear Aspect feature stack in that regard, but could you stack, for example:
- Powerful Build (innate Goliath feature)
- 6th level Totem Barbarian Bear Aspect
- Brawny feat
Essentially, could you double your carrying capacity and lift/pull capacity thrice?
