Lord of Hunger Zeta

It’s a debuff that it making a fast Darth Nihilus Cooldown of the last move. Ebb and flow is better.

Health down = temporary lower health pool. The rancor does it too. The advantage, other than having an extra debuff for Nihilus’ drain force, comes after you exhaust an enemy character’s protection. Less health = fewer hits to kill.

Thrawn’s Ebb & Flow makes Thrawn a much less viable target when anyone’s fractured. He will rarely get debuffed and always counters. It also keeps the fractured character out of circulation a bit longer if Thrawn has other Empire characters on his team.

Thrawn’s is probably useful in a wider range of situations, but Nihilus’ seems like it can be worthwhile in arena.

I would recommend against the Nihilus zeta right now. 3 months ago I would have said to get it because spreading debuffs helps feed TM under Palp lead and increase the chance of drain force working.

Now though applying a debuff means you give the opposing Nihilus 10% TM every time the opposing Traya or Sion takes a turn. Probably not worth it

If you use sith assassin as your 5th, having the health down buff on a toon will let her one-shot some toons much easier with her 2nd special. It may also affect how much health nihilus stacks from his unique, although I can't say that for certain.

I use both Raid Han and Chirrut in my arena team, and if han stuns their vader, then chirrut almost always goes first (257 speed). I hate fighting against this zeta as it means that Han and Chirrut both get health down, so they don't get tenacity up, which makes fighting sith teams so much harder.
