Kahrk is a 12th-level ogre mage that will be released in the Firewine Bridge area if Gorion's Ward and their party demand that Carsa surrender her jar. He emerges from the jar with three spells active:
|“||I am free... at last. Mortals, before you die, know that you have pleased KAHRK, mightiest of the ogre magi. Your deaths shall feed my power, for now I am weak.||”|
Waiting for the buffs to wear outEdit
This strategy requires some careful positioning of a single party member. Leave the party behind, take one character (preferably wearing the Boots of Speed) and slowly approach Carsa's location until she appears at the edge of the fog of war and initiates conversation. Then, once Kahrk appears and ends conversation quickly retreat to the party's location. If done correctly, the ogre mage will not follow. Then wait for around 5 minutes real time or sleep for 6 hours ingame and Kahrk's protective spells should have worn off. He cannot recast them, so slay him any way you want.
Kahrk's Minor Globe of Invulnerability does not save him from wands and higher-level spells (above 3rd level). Use Cloudkill, Flame Strike, Wand of Frost, Wand of the Heavens, etc. can dispatch him even with the protective spells on.
Protection from Normal Missiles does not affect enchanted arrows, enchanted bolts and enchanted thrown weapons (of +1 or better quality). It also does not affect elemental damage done, so Flame Arrows will deal only their fire damage. Use this to pelt Kahrk with missiles.
Arrow of SlayingEdit
The Arrow of Slaying is the ultimate anti-ogre mage weapon. A one-shot kill. There's only one of it in the entire game, though, so plan carefully against whom to use it. Kahrk is among the most dangerous ogre mages (if not the most powerful), so it might be wise to use it against him. Just make sure that Mirror Image is not active when you do.
