Due to changes to hunger mechanics by terrafirmacraft, the degradation of vampire blood reserves from Vampirism - Become a vampire does not work, resulting in the amount of blood not decreasing.
This mod adds a script that starts tracking the thirst parameter from tfc (which works almost like vanilla hunger) if the player's vampire level is equal to or greater than 1, and in the case of decreasing the thirst parameter below 99/100 (can be changed in the configs) reduces the amount of blood, and instantly restores the thirst parameter to the maximum.
My Java skills are pretty mediocre, so I used AI to help me write the code.
Obviously you need vampirism and terrafirmacraft mods:

Future plans: add trees from vampirism to tfc forest generation, and create an area around them during generation, overwriting the biome with a vampire forest, thereby allowing unique mobs of this biome to appear in the tfc world.
