Trap assassin runeword priority

Right now, I'm wondering which runeword I should give priority to. Right now I'm lacking two things.
1) Mobility (I have a

Teleport staff in my switch that needs constant recharging)
2) Immunities are slowing me down due to waiting for my merc to finish them off.

Which of the two should I make? Enigma vs Infinity

Essentially the question comes down to this: What is preferred? Mobility vs breaking immunities?
What do you all think?

Either is good, an Infinity will let you farm more places and leave you less vulnerable to light immunes. You can also put quad rainbow facets (banana flavored) in magic trap

Claws socketed by

Larzuk to

Pierce those immunities. both runewords are expensive. It's preference really. Enigma probably has more use cases as it can speed up farming bosses so I would certainly go for the Enigma first.

you can get rid of most light immune thru

Corpse Explosion and the fire bomb.

I'd probably run for enig first
