Spellswords are a Martial class that use Thaumaturgic magic to alter the properties and abilities of a physical weapon into a new form.
They use melee weapons that they can touch and use to channel their abilities. This class typically uses elemental types of magic such as fire and water that they channel through their weapon. Typical results of such channeling are Flaming, Frost, Acidic, Electric or Wind Blades.
They can also channel their mana from themselves into another. This energy is reflected in life force, and channeling too much mana can actually kill the spellsword.
They are capable of using any weapon on the battlefield. They have use of even the heaviest weaponry such as double-bladed battles axes and claymores. These warriors can use critical strike weapons. Note that spellswords attune themselves to one particular weapon as a channel for their mana, and use that specific item in preference to any others.
They can wear cloth, leather, chain or plate armor, but cannot wear the heavy plate allowed to pure warriors. This gives them D2 and magic resistance of M1 on the meter.
