I'm wondering what the most appropriate builds for an undead would be.
The first obvious thing is that it's beneficial to have poison surfaces that are both sapping your enemies' HP and regenerating your undead. That means your undead must be at close- to mid-range.
If your undead is always going to be on a poison surface, then Elemental Affinity reduces the cost of Geomancer skills and would therefore be a good pick.
Taking Geomancer also means you can create your own surfaces without having to rely on another character. For maximum range, the Water+Contaminate combo gives the largest surfaces, so you might want to splash in Hydro (20m with Rain) and maybe Necro.
Leveling up your Geomancer is recommended to have the most effective poison effect possible.
Necro skills or Leech to heal from blood could be useful given you can't heal normally, but taking away blood limits your ability to create poison surfaces with Contaminate or Infect, and physical damage from Necro does not have great synergy with magical poison damage.
Another problem is that you need to stay at fairly close range so that you can benefit from the same surface that's debilitating your enemy, so that means mage is not necessarily ideal.
The closer range makes Glass Cannon much more dangerous than on a typical mage build, and opens the ability to create blood surfaces through physical attacks against the enemy.
Geomancer gives you increased physical armor regeneration, which should help with tanking at closer range. You'll probably want to get Heart of Steel from Polymorph.
Poison is very sensitive to fire, this could be bad news for you. Then again if the enemy is also standing in it, he won't necessarily set it alight as it would damage their own. In any case you probably want to spec with fire resistance and maybe Phoenix Dive for fire immunity.
It looks like undead will be most effective with a very hybrid build, which is more difficult to set up.
Otherwise do we know anything about the effects of cursed/blessed surfaces on undead?
