Base Class: Warlock
You have made your pact with a mysterious entity from the Shadowfell — a force that manifests in sentient magic weapons carved from the stuff of shadow. The mighty sword Blackrazor is the most notable of these weapons, which have been spread across the multiverse over the ages. The shadowy force behind these weapons can offer power to warlocks who form pacts with it. Many hexblade warlocks create weapons that emulate those formed in the Shadowfell. Others forgo such arms, content to weave the dark magic of that plane into their spellcasting.
Because the Raven Queen is known to have forged the first of these weapons, many sages speculate that she and the force are one and that the weapons, along with hexblade warlocks, are tools she uses to manipulate events on the Material Plane to her inscrutable ends.
Hex Warrior
At 1st level, you acquire the training necessary to effectively arm yourself for battle. You gain proficiency with medium armor, shields, and martial weapons.
The influence of your patron also allows you to mystically channel your will through a particular weapon. Whenever you finish a long rest, you can touch one weapon that you are proficient with and that lacks the two-handed property. When you attack with that weapon, you can use your Charisma modifier, instead of Strength or Dexterity, for the attack and damage rolls. This benefit lasts until you finish a long rest. If you later gain the Pact of the Blade feature, this benefit extends to every pact weapon you conjure with that feature, no matter the weapon’s type.
Master of Hexes
Starting at 14th level, you can spread your Hexblade’s Curse from a slain creature to another creature. When the creature cursed by your Hexblade’s Curse dies, you can apply the curse to a different creature you can see within 30 feet of you, provided you aren’t incapacitated. When you apply the curse in this way, you don’t regain hit points from the death of the previously cursed creature.
