Sirene Primer+Standard Actions+Sphere_Spells+Tradition+Somatic Casting x2

You must gesture to cast spells—a process that requires you to have at least 1 hand unoccupied. When using magic, you cannot wear armor heavier than light without incurring a chance of arcane spell failure.

You may select this drawback twice. If taken a second time, you cannot wear any armor or use a shield without incurring a chance of arcane spell failure.

Note: With GM permission, it is possible to modify this drawback so that, when taken once, the caster may wear either light or medium armor but cannot use a shield without incurring a chance of arcane spell failure, mimicking the core bloodrager.
