Boon of Evanescent Blood

Through your training with Bella, uncovering the source of your magic and digging deep within your soul to truly find yourself, you have finally achieved what you've been looking for. Blessed by the goddess of souls, and with your own sheer determination you have learnt to use your blood beyond the rudimentary methods you used previously, harnessing your connection to the weave and very soul to fuel you blood art, and allowing you to see the souls of those around you. After rigorous training you have gained the ability to combust your own blood, empowering it with the energy of your own soul to create a flame capable of burning your enemies far worse than any ordinary flame. You can turn any weapon into your blood weapon, and the blood traces from this weapon now stacks as you fuel the fire with your own life essence, increasing its intensity by every stack gained until the blood evaporates under the intense heat. For each stack on a creature you gain the following benefits. Whenever you mark a creature for the first time with your blood, you create a tiny blood trinket as a display of your bond to that creature.

1 stack - You deal an additional amount of damage equal to a roll of your hit die, plus an additional die for every 2 stacks.
2 stacks - You blood weapon gains a bonus to hit equal to the amount of stacks you have.
4 stacks - You gain a bonus to saves forced from a creature with your blood markings equal to the amount of stacks you have.
6 stacks - Whenever you regain hit points, the amount is doubled.
8 stacks - Once per turn when the cursed creature takes damage, you may use one of your Hemomancy abilities on them.
10+ stacks - When you hit with an attack, you may choose to expend all stacks, dealing an additional 2d10 necrotic or fire damage per stack.
