Lich is DR Magic and Bludgeoning
Clay Golem is Adamantine and Bludgeoning
Skeletons are Bludgeoning
Zombies are Slashing
Raksasha are Piercing and Good
Plant Creatures are often Slashing (though none currently exist in DDO)
there are others but really what is bothersome is the undead ones... do you realize how many of those buggers we fight just leveling up. We must empty the cemetaries twice over just going from level 3-10.
