Prerequisites: 12+ dex AND 12+ chr (higher str needed to wear heavier armors)

This sub-class gives proficiency with all armors (less shields) while casting arcane spells.
While wearing armor, use stealth disadvantages.
Also, all somatic components are hand gestures OR weapon gestures. It is assumed that the caster can cast with either with equal ability.

Along with the stealth disadvantage, you receive a 25% chance to cast another known spell. If the caster isn't wearing armor at all, there is no adverse affect.
On a roll of 1-3 on D12:
1 - 1 lvl lower random known spell
2 - 2 lvl lower random known spell
3 - 3 lvl lower random known spell
4+ - cast the spell as expected.
When affected, it burns the spell level of the spell expected to cast.
If a lvl 1 spell or cantrip is cast, the spell simply fails.
