Perusing
another thread, I thought it might be interesting and useful to discuss tactics appropriate for dealing with various enemies in NWN. Obviously, there may be many things that work against a given opponent and what sort of character is going up against that enemy is also important, particularly for single-player environments. And, environment will matter, so it's worth mentioning if a tactic depends on having an available magic item in that environment, etc.
Anyway, first up: The Demilich. How does one best approach this foe, particularly in a single-player environment with a level 30 or lower character? Is he even beatable pre-epic?
I am particularly interested in how to deal with this guy when playing an arcane caster, though even melee types will have some difficulty cutting through the 30/+20 damage reduction and immunity to critical hits. Obviously, characters with the Divine Might or the Smite Evil feats or the Holy Sword spell will have an advantage here.
The demilich's immunity to all spells of level 9 or lower really kind of limits a caster's tactics. Evard's Black Tentacles are soaked by his damage resistance and Great Thunderclap is only effective as a low percentage chance of increasing his chance of spell failure. My approach has been to throw up Mestil's Acid Sheath, Death Armor, and maybe Elemental Shield (if I'm high enough level to overcome the 20/- fire resistance) and hope to draw him into melee before he wears me down with Breaches and Mord's. Standing next to the demilich with a bow/crossbow to give him extra attacks of opportunity can be useful, though a close eye has to be kept on healing, since his head-butt attack averages 55 damage per hit and has a high-DC paralysis effect.
What approach do others use?
And, feel free to add questions and tactics for dealing with other enemies to the thread.
