Not logged in so I cant see my NL Apocalypse Warlock, but skill level is high. Even my Listener binded demon was suffering, eventually jumped out when I saw his health was down to 50%, my minions were all dead including Merc. My Apocalypse was merely tickling them, I should have thrown comfy pillows at them instead.
Zealer faired better, just could't get it done. Needed an Echoing strike Warlock to help me. On HC, I would definitely ask for help.
