Wampa’s Furious Foe Zeta and Sith Raid

It just means that they can't dodge the debuff so potency and tenacity aren't in play for the zeta. They come in after.

So to answer the question the debuff can and probably will be resisted

I don't have the wampa, but I think it's safe to assume that the debuff can stick but is resistible. Which means you need to engineer it so it's the first thing that hits the boss.

Sion's zeta is a reliable way to inflict debuffs because it's the first thing the boss will get hit by, so he's go no bonus tenacity. If Nihilus is somehow your fastest raid member he'd be reliable debuff source too if it weren't for the adds.

I can't think of any other reliable debuffers other than making Zader your fastest and throwing enough potency on him so one of his dot's stick. Others probably exsist

Thanks for the feedback. I wanted to confirm my thoughts.
I currently don’t have a zader so I don’t think I’ll go that route. More important zetas to be had out there
