Question About Interactions

how does resolute technique interaction with undeniable?

I'm doing a tectonic slam build and my build has me getting these two skills, and i'm not seeing the bonus' from Undeniable taking effect, wondering if they even stack together

You normally unspec RT when you get Undeniable. They will play together in the sense that you will get both the attack speed from Undeniable and cannot miss/crit from RT, but Undeniable gives you 90%+ chance to hit anyways so it's not really necessary to have RT. If you are an elemental build, it's much better to path up to Elemental Overload and unspec RT. Unless you are an unarmed build, which has 0% base crit chance and can't make use of Elemental Overload nicely. Then you just unspec RT and take something else.
