Bloodforge Artisan

As a bonus action, you pour blood or spend 1 Blood Point to temper a held weapon for 1 minute. The weapon deals an extra 1d6 necrotic damage and gains a faint ripple like fresh blood. If the weapon already has a rune, the rune's potency increases (see runes).

When you hit with an attack from a tempered weapon you may convert part of the damage to life: deal an extra 1d6 necrotic; you regain HP equal to half the necrotic damage dealt. This attack also slightly repairs your armor: restore 1 HP to a single piece of your congealed armor (if any).

When you are hit by an attack, you can use your reaction and expend 1 Blood Point to reduce the damage by 1d10 + your Constitution modifier. If the attack hits, the attacker takes necrotic damage equal to your proficiency bonus.

A precise strike that opens arteries. On a hit, in addition to weapon damage, the target begins to bleed: it takes 1d6 necrotic damage at the start of each of its turns for 3 rounds. The target can expend its action to make a Medicine check (DC = 8 + your proficiency bonus + your Con mod) to stop the bleeding.

You make a heavy called strike with a tempered weapon that rends both equipment and flesh. Target suffers weapon damage plus 2d6 slashing and 1d6 necrotic. If the target is wearing armor, the armor takes 1 point of 'wear' (DM tracks); reducing armor effectiveness may be repaired by Hemalurgic Transfer.

You make a sweeping cleave that triggers a minor rune on your weapon upon each hit. Each creature hit must make a Dexterity save (DC = 8 + prof. bonus + highest of Str/Con mod) or suffer the rune's minor effect (bleed, knockback 5 ft, or faint force).

As a bonus action, you surge forward leaving a waking trail of congealed gore in a 10-foot line. Creatures that enter or end their turn in the line take 1d6 necrotic damage and have their movement reduced by 10 feet until they leave the trail.

You unleash a pulse that siphons vitality from creatures in a 15-foot radius. Each creature must make a Constitution save (DC = 8 + proficiency bonus + your Con or Strength modifier) or take 3d6 necrotic damage and you regain HP equal to half the total necrotic damage dealt. On a success they take half damage and you regain half as much. Costs 2 Blood Points.

You can form a piece of gore-armor or a blood-shield in combat. As an action and spending 2 Blood Points you create a one-use gore-shield that provides +2 AC for one creature for one minute or a helmet that grants advantage on one saving throw. The created object collapses after use.

A tempered blade vibrates with stolen life. Once per turn when you hit with a tempered weapon you may cause it to pulse; the target and all creatures within 5 feet take necrotic damage equal to your proficiency bonus. You can expend 1 Blood Point to increase the pulse to 10 feet and add 1d6 necrotic damage.

You may cause a rune to echo after activation, triggering a smaller effect on a second target within 30 feet of the original for no additional BP cost. The echo deals half the original rune effect. You may echo a rune a number of times per long rest equal to your Constitution modifier.

You reach into a creature's life and pull. Make a ranged attack (30 feet) with a tempered weapon effect; on hit the target is pulled up to 15 feet toward you and is restrained until the end of your next turn as blood binds it. The target can attempt a Strength save to break free (DC as usual). Costs 2 Blood Points.

During a short rest you may spend 4 Blood Points to reforge all equipment you created (weapons/armor) and grant each a temporary major rune: choose one — vampiric edge (heals 50% of necrotic damage dealt), warding sigil (+2 AC for wearer), or rending rune (+2d6 damage vs constructs/armored foes). Lasts 24 hours.

When you drop to 0 HP but are not killed outright, you automatically spend 3 Blood Points (if any) to burst in a spray of congealed gore: creatures within 10 feet take 4d6 necrotic and are splashed with runic blood causing disadvantage on attacks until the end of their next turn. You then stabilize with 1 HP. This effect can occur once per long rest.

You can finely tune a tempering to counter a creature's resistances. As an action, you study a creature and choose to pierce resistance to one damage type (e.g., necrotic, fire) for your next three successful hits against it. Requires 1 Blood Point and a short concentration (1 round).
