Farmed some more Hellfire necks. Had to ditch some damage for one. I can only do 48 still, I tweaked my build some more and a little bit 'O fine tuning this morning and I'll make more attempts.
I'm thinking I need to be at least 475 paragon or even 500 to make some ends meet.
Need to max out my gems. I got two sitting at 49 now. Third is like 36 or something.
Found a third Furnace this morning. Ancient still eludes me.
