I haven't actually made Riskbreaker as a usable class yet (I'm new to custom content, but I'm looking for a guide on how to do that). This is more of a concept, I guess. The Riskbreaker will be an arcane caster base class based on the abilities of Ashley Riot from Vagrant Story.

Riskbreakers gain Automatic Still Spell III at first level, allowing them to cast arcane spells in armor with a shield.
Riskbreakers get as many spells per day as Sorcerers, and can cast without preparation. They can also learn spells from scrolls, like Wizards. However, Riskbreakers never learn spells by leveling up and can only learn spells from scrolls (including divine scrolls, if that's even possible).
Riskbreaker weapon proficiency includes dagger, shortsword, kukri, longsword, bastard sword, greatsword, dwarven waraxe, kama, katana, battleaxe, greataxe, halberd, rapier, scimitar, light crossbow, spear, trident, club, and mace. This proficiency group is based on the weapons usable in Vagrant Story.
