Description

Dimensional Anchor is an indirect attack spell which targets your opponent’s legs and inflicts mental damage, although it only inflicts a single point of actual damage. If your spell is successful, a glowing dimensional anchor will materialise around your opponent’s legs, giving them 1% chance per rank of teleportation failure, and increasing the AP cost of their feet commands by +1 per rank. If the feet AP penalty exceeds any bonuses your opponent has from other spells or equipment, they will also suffer +1 feet cooldown.

Note that this spell doesn’t work on swarm creatures, for obvious reasons.
