(Current Content) Question about Corruption Effect. Stack?

Unsure where to post this… So guides made sense.

I have 2 corrupted items with Twilight Devastation(Rank 1). Does this stack in any way? are my beams doubled, or does the damage stack from 6% to 12%?

Or am I simply wasting 25 corruption?

THanks in advance.

According to the icy-veins article on corruption, and everything else I can find on the wow forums, reddit, etc., yes corruption effects do stack. Here’s the article I’m referencing, it’s in section “3. On-Equip Effects”
