Taintlock use conv or insight on merc?
definitely conviction merc unless poverty build, absolutely needed because only -% fire resist that works for tainted is sunder + conviction
My best setup so far has been 2x tainted + 1x bound cursed + holy freeze venom lord (only 1 pt bind needed for TZ mode), and infinity + skin of the flayed one (protector's stone) + cure on prayer merc.
amp+conviction for blood boil, 2x tainted, but no consume/defiler. Shreds everything, whether immune or not
