Ima gun di mods?

I'd say Speed and Protection, probably. Anything isn't super useful for him.

I'm using critical damage avoidance mods and potency mods, since I'm planning to use him in next droid/tank raid. If going to use him for arena, then I'd recommend speed and protection as well. Hope this helps

I'm throwing protection and critical damage on him. He already does double damage to droids, why not make crits even better?

I put defense and crit damage for mods. Focusing on crit chance speed and potency. He already has decent health and protection.

Crit Dmg/Chance.

Here me out, but I put health mods on him. He self heals for three turns on a critical hit. So, in the arena, he is pretty much always healing himself. I have found him to be incredibly durable and I think this has contributed to it.

Are you using him as a leader? Is Anakin going to be on this team?

Survivability for raids...speed and damage for arena. Everyone else on your team will b targeted b4 him in arena...no use making him even more tanky. No matter how tough u r, u still lose when u r let man standing.

Crit chance and crit damage especially if you gave Droid teams.
Also some potency wouldn't hurt so his defense down doesn't get resisted

I would go with Protection as primary stat and a set of Critical Chance + Critical Damage. Probably best combination for him.
