Need advice.

I am thinking of playing a ranged glassy CI character with life leech.

How much ES do I approximately need to aim for and how many ES nodes to take to not get one-shot on merciless so that I can sustain myself with life leech?

3k ES and probably maxed 75-83% resists. ES nodes depends on the gear u can get/buy, since u need to balance ES vs resist and armour/EV.

If u start doing maps u want to have max resists and 4k ES.

U want maxed resist, since as CI user crit ele effects are still based on your org. max. HP. So chill/freeze/stun really sucks as CI leecher.

U also need the unique "stun immunity" amulet, since otherwise u will die to archers who perma stun u and prevent u from leeching.

I also recommend the unique "cannot be frozen" ring, or at least 4xFlasks with remove frozen state.
