Duskblade

Duskblade
Faced with defeat after defeat at the hand of holy paladins, it is said that the first duskblades can be traced back to an experiment by an Overlord of Ramdrant in days gone by. Founded as a dark mirror of the warriors of chivalry, these heavily armored warriors wrought untold havoc on the battlefield, smiting countless foes with their eldritch might. While the secrets of these arcane knights' rigorous training were kept a carefully guarded secret for centuries, in recent years their techniques have begun to filter into the broader populace, and the title of duskblade may go to any sorcerer with the mettle to claim it.

Twilight Infusion
While many claim that Ramdrant holds few resources worth seizing, the truth is that the twilight kingdom thrives upon the eldritch energies that suffuse the land. Even a simple smith might strength steel with simple arcana - and a trained duskblade can do much more. Beginning at 8th level, you gain proficiency in medium and heavy armor, shields, and a single martial weapon of your choice. Additionally, you can weave potent energies into your arms and armor, infusing them with elemental power. When you cast a damaging spell, you can infuse either your weapon or shield for one minute. If the infused item is a weapon, that weapon deals Xd4 additional damage of the same type dealt by the spell, where X is the number of dice of damage dealt by your cantrips. If the infused item is a shield, you gain resistance to the damage type dealt by the spell. Any new infusion in a given item overwrites an existing one, but you can have multiple infused items at once. Finally, whenever you land a critical hit with your infused weapon, you regain 1 sorcery point. This increases to 2 sorcery points at level 13, and 3 sorcery points at level 18.

Twilight Conduit
The creed of the duskblade holds that spell and sword are one and the same, and that the chaos of battle should be embraced and channeled for further devastation. Beginning at 13th level, if you have hit with a weapon attack on your current turn, you can use the Quickened Spell metamagic for a cost of only 1 sorcery point. Additionally, if this condition is filled, you can use Quickened Spell in conjunction with other metamagic effects.

Twilight Onslaught
Few have faced the mightiest of duskblades in battle. Fewer still have survived. But those few have shared the same revelation - that against such overwhelming power, there is truly no defense. Beginning at 18th level, whenever you damage a creature with a weapon attack, that creature gains Vulnerability to the next damaging spell you cast before the end of the current turn, and loses any resistance or immunity to that spell's damage.
