An ancient and strangely serene demon. It regards you coldly from the huge glowing eye in the centre of its forehead.

Useful Info

Lom Lobon is a unique Pandemonium lord and guardian of the magical rune. It packs some powerful cold and electricity damage spells, the most powerful healing spell in the game, and keeps a number of wizards and blizzard demons on hand to assist him. You can find him on his special Pandemonium floor, which has grey floors and white walls.

He has some nasty spells, but he's not too resilient. He'll attempt to blink away and cast either Ice Storm or Conjure Ball Lightning when you get too close. Have rC++ at least, preferably rC+++, and definitely rElec before facing him.
He is generally easier for melee fighters to deal with, assuming they can keep him in melee range for long enough; his melee attack is crippling for casters, but is negligible to an armoured fighter.
If you lack a weapon of holy wrath, antimagic is also very effective against him.
