So basically my idea is to place +25 Spell Penetration in every blue slot. That'll make along with the cloak enchant 135.

The three relentless items with +hit give a total of 150.
Meanwhile I think I'll gem colorless/yellow slots/useless item socket bonus slots with the +16 Hit. I won't go far I think but I'll get gear hopefully and will climb on there.

Red slots I'll go with +23 spell power.

Also Just equipped all with Thunderfall Totem.

Thank you so much for your great help.
