+3 Conjuration DC and +3 profane CON are the 5pc bonus effects. There is no 4pc bonus.That's 4 pieces, not 5, and is definitely not an ideal PM set-up. Losing Demon Consort Bracers for +3 on Web is not very good. 3-piece is pretty nice, but not a big deal.
You have Superior Lore in your weapon slots. Rakhir's set bonus buys you nothing. Sanura's set is redundant as you'll be using Nihil clickies for 75% damage anyway.Ring1 - Rakhir's/Sanura's with +3 exceptional INT Rahkir's is better for buss nuking, Sanura's for your healing and Necro nuking.
150 SP is all that matters. Why wouldn't you get +6 CHA skills? There's not much else worth crafting.Goggles - What GS are you wearing for +6 Cha skills? Wiz VI is a waste, and +1 Cha skills isn't too important, and you can get better effects on a Cha +5 item.
You're either laying down Web, or your zerging ahead to gather mobs up for a Wail/Circle. Wear the appropriate item for the appropriate situation.Belt -Absolutely not solo-only gear. Very useful getting those neg level and Shaken procs when grouping.
