What do you guys think

I’m usuing a ce bone necro and need something to kill fast for ce to work

grief pb and eth mithril or cryptic plague.

act 2 merc with infinity is usually the choice for ce necro since it buffs the fire dmg

An act 2 merc

does might work with the physical damage from ce?

no

Eth infinity might merc

You use amp and corpse explotion.

Eth infi got good damage and good cb as well as bufring u, it also buff merc and summons change to hit if u got those.

There is no other choice in my mind for any nec.
You can ofc make beast golem, or insight golem. Depending on nec type.

If you’re playing a necro you want act2 merc. I only use a5 merc for melee/physical chars because 2x lw gives lvl 34 might aura.
