Bestiary/Ice Fiend

The Ice Fiend is a pale-blue daemon of the frozen depths. It's tougher than a common daemon in melee and casts spells nearly as well.

Overview

In-game name: an ice fiend
Corpse: an ice fiend corpse
Behavior: it attacks the nearest target it sees and fights like a spellcaster (mage AI), mixing spells with melee.

It fights with the mage AI: it closes to melee range but casts between swings. Its Magery is 80.1–90.0 and its Evaluating Intelligence 80.1–90.0.

Damage spells: Magic Arrow, Harm, Fireball, Lightning, Mind Blast, Energy Bolt, Explosion and Flame Strike.
Other spells: about 1 cast in 8 is Poison (only if you aren't poisoned already). It may also Bless itself, curse you (Weaken, Clumsy, Feeblemind or Curse), drain your mana (Mana Drain or Mana Vampire) or Paralyze you.
Healing: it cures itself when poisoned, and sometimes heals itself (Greater Heal when badly hurt), more often the higher its Magery.
Dispel: with 201+ Intelligence it can cast Dispel on your summoned creatures (more reliably the higher its Magery).

Every ice fiend carries:

Gold: about 462–800 in total (from its "Filthy Rich" and "Average" loot)
2 magic scrolls from circles 4–7. With Necromancy enabled on New Bradford, necromancy scrolls can show up too.

It may also carry:

A magic weapon, armor piece or shield (up to 7 chances, from about 33% down to 0.5% each)
A musical instrument (about 2.4% or less)
A level 4 treasure map (1% chance)

Use a blade on the corpse to get:

The Deceit brazier: double-clicking it from within 2 tiles summons one creature picked at random from a list of about 90, and this is one of them. The brazier warns players who step next to it ("Heed this warning well, and use this brazier at your own peril"). It works once every 15 minutes and places the creature within 5 tiles. The summoned creature is set to attack the closest target, even if it would normally leave you alone, and it stays within 5 tiles of the brazier.
