Steelcaster
Steelcaster is a class option for the Warrior archetype. It is one of the first Hybrid classes, introduced in The Chains that Rust. It hybridizes with any class belonging to the Mage archetype.
As a hybrid class, it gets a limited number of skills itself, and cannot gain the high-end skills of the class it hybridizes with. For example, were it to hybridize with the Runemaster class, the Steelcaster would be able to purchase any class card of the Runemaster class (as well as any class card of the Steelcaster class itself) except Break the Rune or Quick Casting, since either of those would cost 3 experience points.
The Steelcasters starting equipment is determined by the Mage class it hybridizes with. Like other hybrid classes, it only receives four skills on it's own, the rest of it's skills dependent on the class it hybridizes with.
