Just got a Cloak of Corruption off a Shadowlord with my Stealth Assassin, and decided to mess around with Meers in Ilsh. Each time the Cloak leeched Life/Stamina from me, it replenished my Mana. I was able to chain AI to death a Meer Eternal with my Vorpal Blade, when this char only has 70 Mana/25% LMC, 6 MR, 40.0 Focus. Normally, i wouldn't of been able to do that, but with the Cloak on i could. It's like infinite mana at the cost of Life/Stamina. Went down to 1 Health from it leeching and it also brough me down to 1 Stamina/1 Mana, but as soon as my bandy applied and healed me, Health, Stamina and Mana went back up.
