Depends on what you’re running I suppose.
I like Delirium for CS if you’re not running some other curse that it will complicate.

I’ve been using Delirium/CoH with Thresher Insight as Blizzard for P8 Infector/Vizier and I’ll probably switch to Infinity Lightning/CL for P8 Nihlathak @ clvl 98. A lot of people like Treachery here (I’m a supporter myself) and it’s a very good budget option but once you have more access to runes Delirium is a really strong safety option for some maps. Not sure it’s necessary for Pits/AT but I like it a lot for CS/Nihlathak/WSK if you’re more focused on XP.

Fuck me, hahaha. Thanks for pointing that out, what I wrote cracked me up. What was I thinking? Ofc shield gets the third socket q if using ss.
