What would be your guess as to the equivalent enhancement weapon bonus for vampiric regeneration ? 
This extremely powerful power was available in 2e but our DM has recently slammed us with a multi-armed demonic creature bearing not one, but TWO vampirtic regeneration weapons (out of four) ! What would be your guess on CR adjustment ?
