There seems to be plenty of soul drainers nowadays like mounts, liberators,
weapons, arkemiles etc.
1. Lich drain should stack with other soul drains.
2. Lich drain should not consume sp's when no souls available. It drains now
-10sp if no soul available.
Draining corpse piles is rare nowadays as corpses weigh a ton, so +spr on pile
drains doesn't count (if it even exists anymore, I lack str for trying it!).
3. Lich drain should not break skills & spells anymore. It's not that superior
feature that it needs to have one more penalty. Losing spell points is enough.
You chant the command words to drain life energy from the corpses.
The souls of the corpses raise to the air and transform into life energy which
you quickly suck and store inside you.
The consumed life force fills your being with ecstacy!
