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.
At 3rd level, you gain the following spells. They do not count against your spells known, and count as warlock spells for you. You only gain the spells when you have spell slots for them. The spells are listed by their spell level.
1st Level: Shield, Wrathful Smite
2nd Level: Blur, Branding Smite
3rd Level: Blink, Elemental Weapon
4th Level: Phantasmal Killer, Staggering Smite
5th Level: Banishing Smite, Cone of Cold
Starting at 1st level, you gain the ability to place a baleful curse on someone. As a bonus action, choose one creature you can see within 30 feet of you. The target is cursed for 1 minute. The curse ends early if the target dies, you die, or you are incapacitated. Until the curse ends, you gain the following benefits:
You gain a bonus to damage rolls against the cursed target. The bonus equals your proficiency bonus.
Any attack roll you make against the cursed target is a critical hit on a roll of 19 or 20 on the d20.
If the cursed target dies, you regain hit points equal to your warlock level + your Charisma modifier (minimum of 1 hit point).
You can't use this feature again until you finish a short or long rest, or use your magical cunning feature.
At 1st level, you acquire the training necessary to effectively arm yourself for battle. You gain proficiency with medium armor, shields, and martial weapons.
Starting at 6th level, you can curse the soul of a person you slay, temporarily binding it in your service. When you slay a humanoid, you can cause its spirit to rise from its corpse as a specter. When the specter appears, it gains temporary hit points equal to half your warlock level. Roll initiative for the specter, which has its own turns. It obeys your verbal commands, and it gains a special bonus to its attack rolls equal to your Charisma modifier (minimum of +0).
The specter remains in your service until the end of your next long rest, at which point it vanishes to the afterlife.
Once you bind a specter with this feature, you can't use the feature again until you finish a long rest.
Starting at 10th 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.
At 14th level, your hex grows more powerful. If the target cursed by your Hexblade’s Curse hits you with an attack roll, you can use your reaction to roll a d6. On a 4 or higher, the attack instead misses you, regardless of its roll.
