Magimorphosis

Spells, at their fundamental nature, are thoughts without bodies. Just as all spells are, to a much lesser extant than a human, sentient, they are able to grow and change, especially when put under sufficient stress. When a magic spell from a Grimjelly is cast under stressful or dangerous conditions, it might change. This process is called Magimorphosis

Grimjelly (Mutate Spell)

This process can be triggered on a spell in a grimjelly by casting a spell of Mutate Spell

Morph Mutations

This same process can also apply to Mutations. Typically, this is at GM discretion but is made more likely by the presence of certain other mutations.

Procedure

When a spell or mutation morphs, either by the fiction or by magic, roll twice on the Basic Adaptions table. Results not on the table or that cannot be feasibly applied to the magic do nothing.

Grand Adaptations

When purposefully morphing a spell, the player may choose to permanently break an item that takes up at least one slot in their inventory. The item must also be valuable, either to the spell or to the character. To gain something, something of equal value must be lost. If they do, instead of rolling twice on the Basic Adaptions table, they roll once on it and once on the Grand Adaptations depending on what they’re attempting to morph, either a spell in a Grimjelly or a mutation on a creature
