The Blood God

You have made a pact with the Primordial being Kashtul, who demands blood to be spilled in his name, and in return he bestows life to his devotees and their lands. Kashtul is not inherently evil, but due to his demand for blood, it is understandable why outsiders may view him as such. Your pact allows his power to flow through you, as well as his hunger. Kashtul feeds on the bloody sacrifices made in his honor and gives life, beauty, and strength in return.

Sacrificial Tool

Starting at 1st level, you may declare a single melee weapon that you are proficient with to be your sacrificial tool. Once per turn, when you deal damage with this weapon to an enemy with blood, you regain hit points equal to your Charisma modifier. Minimum of 0

If the player chooses the Pact of the Blade option at level 3, the pact weapon automatically counts as their sacrificial tool. This extends to ranged weapons if the player chooses the Improved pact weapon invocation. 

Kashtul's Gift

Starting at 1st level, Kashtul grants you the ability to empower your attacks. As a bonus action, the player may sacrifice some of their hit points to give a bonus to their next Sacrificial tool attack. For every 3 hit points sacrificed, the next melee attack gains +1 to its attack and damage rolls. For example; if the player sacrificed 15 hit points, the next melee attack would have +5 to both its attack and damage rolls. This damage increase may also be added to weapons that are already imbued with magic from another source. 

Kashtul's Gift also enables the player to use their spell casting modifier instead of strength or dexterity for their attack and damage rolls when using their Sacrificial tool.

Kashtul's Hunger

Starting at 6th level, you share your patron's hunger. As an action, you may touch any recently slain creature and absorb its blood to heal yourself. You regain hit points equal to twice your level and can feed in this way twice per short or long rest.

Pure Blood

Starting at 10th level. Kashtul blesses your blood and grants you immunity to poison and disease.

Kashtul's Favor

Starting at 14th level, when you fall below half of your maximum hit points, Kashtul restores all of your expended spell slots, so you may fight on in his name. Once this blessing has been used, it cannot be used again until after a long rest.

In addition to regaining your expended spell slots, the first healing spell used to heal you gives the maximum hit points possible.
