Okay, so my real plan was to add a Shapeshifter school, since it's always been a favorite of mine.
I want these features:
1. A new spellschool, like Pyromancy and the like.
2. New books with supplementing spells.
3. New spells.
The spells would work like this:
1. Combat transformation
You take the form of a creature capable of combat (orc, spider, elemental, and so forth). Ideally you should get some new skills with it, but for now I simply want to mute the caster, so that it's melee focused. You also get boosted stats.
2. As a minor thing, I thought it could be fun to transform into a normal animal, like a cat or a dog, and gain the trait Pet Pal. This is nice to have rather than must have, though.
I'm thinking there should be 1-2 shapes per spell level, with an approximate amount of 12 shapes. These would range from undead to elementals to dragons. They should be a strenght or dex based alternative to mages, but should not get bonuses from weapons and the like. Instead they use their claws/natural weapons and innate abilities, and therefore the stats should be fixed (with a possible increase from high int).
I am really in love with this idea, and I played this role a lot in Neverwinter Nights, where I know that many others also loved it. I hope I can create something like this, and I hope you guys can help me get there somehow, so we can all have a shapeshiftin' good time
