Grips a creature's soul in chains of ice. When it dies, its corpse freezes and splits, transforming into icy replicas which serve the caster. Simulacra cannot leave the level they were created on. The number created depends on spell power.

Simulacrum is a level 6 Ice/Necromancy spell which creates simulacra from a dying monster.

Useful Info

Casting Simulacrum irresistibly grants the Simulacrum enchantment on a single living, demonic, or holy monster anywhere in line of sight for 20 + 1d(pow/10) turns[1]. When the monster dies, it will create 1 + 1d(pow/40)[2] (1-6) simulacra. Simulacra last for a finite duration or until you leave the floor they were created on.

The simulacrum created will have the same HD as the original monster. They deal 80% their original physical damage, but a great amount of additional ice damage, so the damage output of creatures with multiple attacks is greatly increased. When killed, simulacra leave behind only a short-lived freezing cloud.

Simulacrum takes priority over Animate Dead and Necrotise. Infestation overrides Simulacrum, while Death Channel works alongside it. Simulacrum does not work with Gozag (who turns corpses into gold, first) or Yredelemnul.

Tips & Tricks

  • Simulacra often have extremely large damage output, but are outstandingly frail. Be mindful of fire attacks, capable of wiping out your horde in a few turns.
  • Focus on capturing monsters with a large amount of attacks per turn, or auxiliary movement-impeding effects like trampling or constriction. Dragons, hydras, tentacled monstrosities or entropy weavers are all fair game. The Lernaean hydra as a simulacrum can deal over 1000 damage per turn.
    • Conversely, try to avoid using Simulacrum on physically deficient mages whose danger level fully depends on their spells, such as wizards or the more magic-attuned among the deep elves. Infestation will return more interesting results, in this case.
  • Slimes of all flavours tend to be impressive when turned into simulacra, and are very easy to create in impressive numbers in the Slime Pits due to their sheer abundance.
  • Simulacra are immune to cold, which means spells such as Ozocubu's Refrigeration can be cast safely without angering them. Polar Vortex is off-limits, however, as a portion of its damage bypasses cold resistance.

Monster Version

Monsters have access to Bind Souls, which is a similar effect. They cast it on their own allies (still hostile monsters), it works on every target in sight, but it can only create one simulacra per monster. Bind Souls takes priority over your own Simulacrum spell.
