some of the mutations i have so far are
>fleshshaping
crippling deformation, deformations, alien fratures, animal features, weakening of the body, premature ageing
>elemental
suseptability to an element, deformation related to an element
>protean sorcery
deformation involving non-living matter integrated into flesh
>evocations
supernatural mutations, spiritual damage
>mesmerism
insanity, retardation

Seems like a fine enough list, but if you use Evocation as non-elemental effects its going to confuse people since Evocation was the original school of magic where fireballs and lightning bolts come from.

I like it at least because it doesn't force players into using elemental magic, since I'm not a big fan of that.

If my understanding of your concept is correct, then you need some sort of passive variable that can be manipulated by what level the spell is cast at.

For example:
Mutation index:
>1-5
Healing spell Levels:
>1-10

Cleric John Smith casts Light Healing at Level 2, of which the spell has a Mutation Index of 1. He fucks up. The Mutation Index is multiplied by the Spell Level and gets a mutation of Grade 1

Mutation Grades:
>Grade 1 = 1-10
>Grade 2 = 11-20
>Grade 3 = 21-30
>Grade 4 = 31-40
>Grade 5 = 41+

Then its just up to the DM to describe what sort of mutation happens. This could be from a generic list or heavily specialize based on the situation. Keep it flexible. In this case Cleric John Smith might get a small patch of skin blight on his arm.

More extreme examples
>Necromancer Jane Doe casts Wither. She fucks up. Wither has a MI of 4 but she cast it at Level 6. That gives us 24 and thus, a Grade 3 Mutation. At this point Jane doubles over screaming as her entire arm, bone and all, instantly liquefacts and sloughs off into a puddle of putrescence.

>Bard Tommy Lee attempts to cast Mass Telepathy to scour the city for any signs of the cult. He fucks up. Mass Telepathy has a MI of 3 but he had to beef up and cast it at Level 12 in order to get the whole city. That gives us 36 and a Grade 4 mutation. His mind forms a sort of psychic stoma and now their is a constant stream of bits of thoughts leaking from him all the time.

I chose evocation for the dictionary definition not the D&D definition.
I'm glad you think I have enough but I would like a few more just to even out the other disciplines.

I'd be grateful for any suggestions.

No I already have that worked out I just need the effects of messing up a spell.

Perhaps:
Mesmerism
Synesthesia, numbness, blindness/partial blindness, deafness, etc.

Mesmerism seems to be focused towards affecting perception as well as the mind. All of the other ones seem to have effects that can be lived with, dealt with, or adjusted to but mesmerism just going straight for insanity or retardation seems a bit extreme.

What exactly do you have in mind for evocation's "supernatural mutations"?

Thank you those look like some good ones.
>but mesmerism just going straight for insanity or retardation seems a bit extreme.
My list needs to be rounded out more but I couldn't think of any others.
>What exactly do you have in mind for evocation's "supernatural mutations"?
My homebrew I'm working on is fairly sandbox. It has a monster generation section that has various features the mage can get

>>44099884
I was doing basically this in my setting and I used the metamorphica for inspiration. Have you looked into that?

>>44101602
Am now.
Thanks
