Stable modification of known Spells:
Instead of creating a new spell for every use case, or searching for a scroll/teacher, a Weaver may choose to modify a known spell instead.
In contrast to Spell modification - On the Fly, this is a more permanent and stable approach.
This can not alter the underlying spell fundamentally. For that use Creating new Spells instead.
Examples:
- Adding an explosion and and “homing” to a fireball is a modification.
- Transforming a fireball into a rain of fire or firestorm is an invention.
Modifications use the same rules as Spell Creations except for the following:
- The effective CP-value is based on the modification, not the entire spell
- The difficulty modifier is far more forgiving (See below)
- When determining side-effects, halve the GM-Roll is halved (round up)
