Rune of Stasis

The Rune of Stasis is a runic spell that appears in Ultima Underworld II.

Description
The Rune of Stasis places a magical ward at a fixed location, which takes the form of a floating Tym character. After it has been cast, any creature which touches it will be frozen in time in a magical state of paralysis. This spell, and others like it, may be unwoven through use of the Dispel Rune incantation. 

Trivia

 * It is possible to bypass the Rune of Stasis by hurling an object into it, although the item will be damaged and possibly destroyed in the process. Pieces of refuse or gold coins (which have no mechanical damage ratings) are useful for such actions.
