MP Cost for Possession Attempts

From MRQWiki

Overview

In the rules as written for Possession a spirit can make one possession attempt per Combat Action with no limit on the number of attempts. A spirit could, in practice, just keep attempting possession over and over until it succeeds.

The Rule

Each possession attempt costs 1d6 MP success or fail.

Make the roll at the time of the attempt (before rolling). The spirit may still use MP to boost his chance of success after the cost is rolled. If the roll reduces the Spirits' MP to 0 the attempt automatically fails and the spirit is effectively dissipated until it is restored to 1 MP.

Variations

If you use criticals and fumbles with opposed rolls have a critical always cost 0MP or 1MP and a fumble cost 6MP or 2D6MP.

Fix the cost at 3MP or 4MP.

Have different cost values for success and failure (failures cost more).

Notes

This rule limits the number of total possession attempts because the spirit will run out of MP eventually.
