Envelops the caster's body in a protective layer of thick ice, granting a substantial bonus to armour as long as they remain in their current location. The ice will crack and fall away if the caster moves to a new position. The spell decreases in effectiveness in heavier armour, granting a lower bonus the higher the encumbrance rating of the caster's armour.

Ozocubu's Armour is a level 3 Ice Magic spell which can greatly increase your AC, provided the player remains stationary.

Ice Elementalists begin with this spell in their libraries.

Effect

The caster gains a boost of AC for a short duration. This spell is less effective for casters wearing heavier armour, and won't work alongside Statue Form. The duration and size of this AC boost is shown below:

Normal AC Boost: 5 + (4*Spellpower/50) AC. (Max 13)

Penalty: - (Encumbrance/2)

Duration: 20 + 2d(Spellpower) turns.

For the spell to remain in effect, the player may not move. Players can still move, but the armour will break - even during "involuntary" movement: e.g., being teleported. In addition, taking fire damage from beams greatly reduces its duration.

Strategy

Ozocubu's Armour can be a very useful spell, providing a large AC boost to any character who can manage the minimal skill investment required to cast it, and who isn't wearing heavy armour. Even at its lowest spellpower, it's still on par with a ring of protection. Species with no body armour slot (Felids, Octopodes, and Draconians) can and should keep an eye out for this spell, while other species are given more lenience while wearing lighter pieces of armour.

Frozen Ramparts is a natural fit; it too is a level 3 Ice Magic spell that breaks when you move.
