Prismal's Reversal (Wizard Spell)

This enchantment reverses the relative veloc­ity of an object or creature that passes through the affected portal. The spell can be cast only upon an area bounded on four sides by a solid frame, such as a window or a door. The spell cannot be cast on a portal smaller than 3 feet by 4 feet or larger than 18 feet by 24 feet. Creatures running or objects flying through the portal lose velocity, while those moving slowly are acceler­ated.
The chart shows the time required to pass through the spell's effect compared with move­ment rates. Once into the portal, a creature cannot withdraw or take any other actions until the portal has been passed completely. If pass­ing through the portal takes a round or more, a creature caught in the frame loses any defensive Dexterity benefits until it clears the portal.
Prismal's reversal is resistant to the dispel magic spell. This has a 1% chance per level of the caster to negate the reversal. Physically de­stroying the frame ends the spell immediately.
Prismal created this spell as a theft deterrent. Since thieves are apt to run from an establish­ment, this spell makes them easy to catch (a full-speed sprint can be five times the standard movement rate).
The material component is a set of four matched ornamental stones, worth 400 gp in all, which are inset in the portal's frame. They crumble to dust as the spell is activated.
Notes: Very rare. Known to be in Prismal's Pocket Library, Vol. IX.
