Blood assassins are martial hunters who turn pain into precision. They use blood rites to empower blades, misdirect enemies with brief-lived doubles, and vanish through shadow to strike from impossible angles. Their niche is mobile single-target damage with short bursts of defensive misdirection; their strongest techniques cost hit points, so reckless power has a price.

Dexterity
ConstitutionYou gain proficiency with simple weapons, martial weapons, light armor, thieves' tools, and one type of artisan's tools or a gaming set.
Once on each of your turns when you hit a creature with a finesse or ranged weapon, you can deal an extra 1d6 damage if you have advantage on the attack roll or an ally is within 5 feet of the target and isn't incapacitated. The attack must use a finesse or ranged weapon. This damage increases as shown in the class table: 2d6 at 3rd level, 3d6 at 5th, 4d6 at 7th, 5d6 at 9th, 6d6 at 11th, 7d6 at 13th, 8d6 at 15th, 9d6 at 17th, and 10d6 at 19th.
You learn blood rites powered by your own vitality. You have a pool of Blood Dice, each a d6; you have a number equal to your proficiency bonus and regain all expended dice when you finish a short or long rest. When a feature calls for a Blood Die, you can spend one and lose hit points equal to the number rolled; this loss can't be reduced in any way, and you can't spend a die if doing so would reduce you to 0 hit points.
As a bonus action, spend a Blood Die and coat one weapon you are holding in your blood for 1 minute. Once on each of your turns when you hit with that weapon, deal extra damage equal to the Blood Die roll; choose necrotic or the weapon's normal damage type when you activate the rite. The rite ends early if you are incapacitated or coat another weapon.
Choose an Assassin Archetype that shapes your methods: the Blood Double, the Dusk Stalker, or the Red Reaper.
When you use Crimson Edge, you can coat two weapons you are holding with the same Blood Die. The extra damage applies only once per turn, regardless of how many attacks hit.

Your Hemorrhage damage becomes 3d6. Also, when you roll initiative and have no Blood Dice remaining, you regain one.
As a bonus action, spend a Blood Die to cast the shadow-step rite. Make a melee weapon attack with a dagger against a creature you can see within 20 feet; on a hit, you teleport to an unoccupied space within 5 feet of it, behind it if such a space is available. This movement does not provoke opportunity attacks, and the die is spent whether the attack hits or misses.
You gain one additional skill proficiency from the class skill list, and your Hemorrhage damage becomes 4d6.

Blood assassins are martial hunters who turn pain into precision.
They use blood rites to empower blades, misdirect enemies with brief-lived doubles, and vanish through shadow to strike from impossible angles. Their niche is mobile single-target damage with short bursts of defensive misdirection; their strongest techniques cost hit points, so reckless power has a price.
You are a mobile striker who creates advantage through positioning, then commits to a high-impact hit.
Use Hemorrhage when its trigger is available, and save Blood Dice for moments where a rite can turn a dangerous fight: every die costs hit points as well as a limited resource. Shadow Step is a close-range repositioning tool, not a substitute for planning; coordinate with allies so you can reach isolated targets without being stranded.
Most candidates begin as scouts, cutpurses, soldiers, or survivors of violence.
A mentor teaches them to make a controlled cut, focus through pain, and shape a small blood rite without losing themselves to it; apprentices graduate only after proving they can refuse a profitable but unjust kill.
Ordinary people may admire a Blood Assassin who protects them, but their blood rites inspire unease even among allies.
In places where assassins are feared or outlawed, a visible crimson weapon can end a conversation—or start a hunt.
