My Unbalanced (for now) OC Subclass

This is my first time posting one of my creations onto this platform. I created an idea for my OC in dnd, and this warlock patron is what I came up with. I’ll post the actual character later (may or may not draw it; I suck at drawing), but I proudly present my Bloodweaver Patron warlock. The spells in the spell list are all homebrew, and are detailed below the subclass itself. I would love any balancing or flavor feedback you all have. I tried to balance it right out of the gate but I am relatively new to this (I have made one paladin subclass that is ready for play). Thanks in advance!

P.S: VGtMM stands for Volatyle’s Guide to Marvelous Magic, which is the imaginary book I use for all of my homebrew whenever the name is the same of real dnd stuff.

Bloodweaver Patron

"Your patron has mastered death by extorting the very thing that all creatures use to survive; blood. It drives the function of civilization itself. When you learn to master it through your patron, great power to change the world, for better or for worse, falls into your hands. Use it wisely.”

Bloodweavers are masters of life and death and do so by manipulating the life-blood of creatures in the multiverse. Typically hungering beings that seek to grow in strength and power, they grant their most devoted followers the ability to manipulate blood and death to grow stronger with the tides of war.

Level 3: Bloodweaver Patron Spells

The magic of your patron ensures you always have certian spells ready; when you reach a Warlock level secified in the Bloodweaver Spells table, you thereafter always have the listed spells prepared. 

Bloodweaver Spells 

Warlock Level	Spells
3	Asphyxiation, Vampiric Might, Reap
5	Leech, Aura of Desecration
7	Serve the Balance, Mortal Coil
9	Bloodweave, Hemoturgy, Hands from the Dead

Level 3: Pull of Demise 

You have mastered the ability to pull creatures towards their doom. On your turn as a magic action, you can choose a bloodied creature within a number of feet of you eqaul to five times your proficiency bonus. The creature must succeed on a Constitution saving throw. On a failed save, the creature takes necrotic damage equal to your Warlock level and Charisma Modifier, and you restore hit points equal to half the damage dealt. On a successful save, the creature takes half damage and you restore no hit points. Regardless of the save, if the creature dies, you can expend a Bonus Action to restore a total number of hit points equal to the damage dealt to a number of creatures within 30 feet of you equal to your Charisma Modifier (minimum of one; this can include yourself). You can use this feature a number of times per Short or Long rest equal to your proficiency bonus. 

Level 6: Vampiric Blood 

You can take life force from the dead as well as the living. On your turn as a magic action, you can choose a number of corpses (including Undead, according to DM descretion) within 20 feet of you equal to your proficiency bonus. Each corpse dissolves into dust, taking necrotic damage equal to your proficiency bonus if it is an Undead. For each corspe or undead affected in this way, you gain a number of temporary hit points equal to your proficiency bonus. These temporary hit points expire after one minute or at the end of combat. Once you use this feature, you cannot do so again until you finish a Long Rest, but you can restore your use of it by expending a Pact Magic spell slot. 

Level 10: Hungering Being 

Your seeking of greater might has led you to feed on the deaths of others. Whenever a creature within 15 feet of you dies, you gain temporary hit points equal to your Warlock level. These temporary hit points stack with your Vampiric Blood feature. You can use this feature a number of times per short or long rest equal to your proficiency bonus. 

Level 14: Bloodweave 

You can now weave blood like fabric. Temporary hit points gained from your Bloodweaver Patron features or your Bloodweaver Patron Spells stack. In addition, whenever you use any other Bloodweaver features or cast a spell you always have prepared from the Bloodweaver Patron Spells, you can deal necrotic damage to a creature equal to the amount of Temporary Hit Points you have. You can use this feature a number of times per long rest equal to your proficiency bonus.
