THIS ITEM has been on my long list of builds to try for a long time.
I went first for a Pyromancer but couldn’t find balance between damage, defence and especially energy management.
So I tried a Warlock instead. I can spam Obsidian Tremor easily with high energy leech.
With Maiven’s SP, Posession, BoD and MoE as an emergency red button and the Devotions (Charriot, Ghoul and Giant’s Blood), I tought this would be good enough. It feels quite squishy and Lokarr just rekt me.
One has quite a few MIs and another uses parts of the darkblaze. This is likely what you are refering to.
I’m curious: did you test anything similar? I’m not suggesting that you should, but just interested to know how it went. I did browse over those builds without much thought. They had energy issues?
I’ve tried messing around with a 'lock as well, but I don’t think it’s viable. I’m both simultaneously surprised and unsurprised that valinov made it work.
Cool builds - I used this based on an old Aether Clairvoyant Juggernaut build way back. Fun, but it definitely needs cast speed. Maybe add cast speed to SWB as well?
Demo 33% chaos res, inq 25% chaos res, devotion 35% + acid spray 28. Total of 121 chaos RR.
