I can make and control conversed vampires.
I must touch blood or it's analog of living beings and induce conversion into vampire variation that depend on my capabilities.
I can make free vampires without any sire bond or dependent on my existence.
I can't transform alpha or higher but I can collect Information from all vampires and learn.
If I convert normal human it became just vampire with blood dependency and enhanced human physiology (2 times stronger than average human with faster regeneration and longevity, always in optimal condition, no need of oxygen ) but if I find strong animals , mystical beings I can use their body properties to make better vampires. If I find dragon ,gorilla analog , some sort of horses or cheetahs i will have capabilities to create superhuman level vampires with less dependency and maybe esoteric power.
