Empower just like glasscanon affect HP after Bloodmagic so that is why your HP is lower than expected.
Hi i have some problem with my vampiric touch set,it says in the dictionary that it will increase 50% bleed dmg and total hp per rank but i only got 125% bleed dmg and total hp for 5 sets.
there is no problem in that. vampiric touch set's bleed damage increases by 50% per set level so a 5 set rank would be 125% bleed damage
Vampiric touch in the dictionnary is bugged. As shown in the Item Description it gives 25% per rank.
