The one change Dom2 really needs.....

[PvK]

As for the original subject, life drain weapons, it would be nice to have a "no life drain" mod that changes at least the life drain magic items to something else, or gives them very high costs, even if only as a game option for people who would like to play some games without them.

Personally I tend to think the effect is simply modelled too strong. It's too often that the life-drainer gets all his damage and fatigue healed every turn. If the effect were a lot weaker, that could balance it, though that's not currently mod-able.

Zen's approach of increasing the cost seems very appropriate to me, too. My personal choices would probably be around:

Wraith Sword: Con 6, Death 4, 40 death gems.
Hell Sword: Con 6, Blood 4-5, 40-80 blood slaves.
