Transforms the caster into a venomous, spider-like creature. The caster becomes highly evasive and gains a poisonous bite, but gains vulnerability to poison.

While transformed, any equipped weapons and armour are melded, and casting spells becomes slightly more difficult.

Spider Form is a level 3 Poison/Transmutation spell that transforms the user into a spider-like creature.

Transmuters start with this spell in their library.

Useful Info

Casting this spell gives you Spider Form for a spellpower-dependent duration. You'll gain the following:

Combat

Resistances

Restrictions

Other

Like all form changing spells, mummies, ghouls, and bloodless vampires cannot use this spell.

The duration of the transformation is 8 + 2d<power> turns, capped at 60.[1]

Strategy

Spider Form gives access to venom-branded attacks. A dagger of venom is a strong weapon up into Lair, and spider fangs are even better. Once enemies are extremely poisoned (3 poison drops in Tiles), you can back off, letting the toxins do their work. It also gives a bonus to EV.

However, Spider Form has several downsides:

  • The evasion bonus is helpful, but be aware that when monsters do manage to land a hit, you'll have very low AC to reduce it.
  • While Octopodes and Felids don't have much AC to begin with, both species still lose something with spider form. Octopodes lose their constriction. Felids lose their fast movement speed.
  • rPois- is a liability against adders and the like, unless you happen to have poison immunity.
  • You can't throw things like darts in Spider Form.

By the time you enter Lair - a branch with many poisonous enemies, and many enemies with rPois - Spider Form starts to get weak. Even if you ignored all the poison, the lack of any AC or SH becomes very noticeable. Transmuters will want to upgrade to Ice Form, or stick to base unarmed combat.

With that being said, it can be great in the early Dungeon. Transmuters can afford 1-2 levels of Poison Magic in order to get the spell running. Even at 30% + failure, this spell is reasonable to use - all you need is 1 successful cast in order to transform.
