Devouring Diadem + CWDT 20lvl dysfunctional interaction

So Devouring Diadem will not trigger build in Feast of Flesh every 5s anymore when you have lvl 20 CWDT slotted into the helmet.

CWDT would NOT trigger Feast of Flesh tho. Looks like either broken interaction or unexpected effect of CWDT lvl 20.

This is not a bug. Supporting a skill by more than one trigger condition will disable the skill entirely. By socketing Cast When Damage Taken you're supporting Feast of Flesh with two triggers, one from the hat and one from CWDT.

Yep, @twitticles is spot on here so no bug here but error 40. :=)
