HALF mana in combat

[Telstar]

Anyone experienced this bug?

My poor mage is sick with an unknown mana drain each time she enters combat, half of her energy goes poof ;)

I believe you have a item that does this? Skull of Pain or something?? Read the description of all your equipped items carefully.

I double-checked my inventory and yea, i had the skull of pain.
