Here's a concrete suggestion. It needs cross-references to Covenants.
Disaster (p. 109): Replace the table with the following:
You fail miserably. Roll a simple die + risk modifier – Perception, and compare to the following chart. Suffer the effect for the number you roll and for all lower numbers, unless explicitly told otherwise. For example, an explosion (7–8) also destroys the creation and inflicts Warping Points on the magus.
Roll Result
0 or less You spot the disaster before it occurs. Your season is still wasted; see Complete Failure.
1–2 Everyone in the lab gains Warping Points equal to the number of zeroes on the botch roll. Hermetic magi must roll for Twilight if they gain two or more.
3–4 Your creation is destroyed. If it is a single-season project, this is the same as a Complete Failure.
5–6 Your laboratory gains the Damaged Flaw.
7–8 Explosion! Your laboratory gains the Wrecked Flaw (instead of the Damaged Flaw), and anyone in the laboratory takes two Heavy Wounds.
9+ The storyguide picks one of the following.
A story event threatens the whole covenant. This may arise immediately from the explosion (a mundane fire, for example), or may be a lingering after-effect of the uncontrolled magic, causing a story some time later.
The explosion completely destroys the laboratory. The structure gains the Deformed and Unstable Flaws, and the whole laboratory must be rebuilt from nothing, rather than gaining the Wrecked Flaw. Anyone in the laboratory takes an additional Incapacitating Wound.
Special or Story Event (p. 109): Replace with the following:
The storyguide picks one of the following.
The creation requires additional raw vis. The magus must spend a number of additional pawns of vis that match the Technique or Form of the project equal to the magnitude of the effect (including modifications) plus the risk modifier. If he is unable to do so, either because he does not have the vis, or because he cannot handle enough vis in a single season, treat as a Complete Failure.
A story event happens. This can be anything; it could be used as an opportunity to introduce a major plot line, or as a brief and amusing distraction. It does not need to happen immediately; the uncontrolled magic might set something in motion, or it might be a result of using the creation in a particular context, some time later. The story event may be basically positive — the magus might attract the attention of a potential familiar, for example. Unless the story event requires otherwise, treat this as No Extraordinary Effects for the project itself.
Hey, there's an idea!
