Diadem stacking with Angel of Vengence Core?

[janave]

Could anyone test if the Deific Diadem (cap) from the Mark of Death raid stacks with the AoV Core: Vengeful Magic - * below 50% hps +1 sacred spell DC* ?

It will not stack, it's the same sacred bonus source. However, EA: DC bonus will work together and stack.

Hmm.. It still worth it. Since +2 sacred bonus will replace +1 from Vengful Magic, and you don't need to be below 50%.

Edit: if you looking for 20th reward, better choose litany 1st. Profane bonus will greatly overcome negative level and it's +1 DC to all spells. 2ndly deflic :)
