Hello there...
I know dodge bonuses from different sources stacks with each other...
But is it possible to choose the dodge feat multiple times to increase the dodge bonus?
You cannot take a feat multiple times unless it says so in the "Special" addendum at the bottom of the feat. There are some feats that allow you to take them multiple times and each time you take it they apply to different things but don't stack, like Weapon Focus, but there are feats that do in fact stack with themselves, like Fleet.
Roger that, thanks!
Anytime :)
