Ingredients for Potion of Transformation
-1 dose purest midnight tears
-1 dose venom from a wyvern killed within the last 60 days
-1 quart unicorn blood
-1 quart blood from a vampire lord or vampiric thrall (should be noted that the former increases the chance of the ritual's success, but I'll make do with what I must in a pinch at my own peril)
-The heart and 1 quart of blood of a humanoid killed within the last 24 hours (can be same as sacrifice)

INSCRIPTIONS UPON THE PHYLACTERY ARE AS FOLLOWS
[A bunch of weird-looking mystical runes, along with a drop of what looks like dried blood]

[several obscure-ish and hard to grok looking notes here on how to properly attune one's soul to what's called a "phylactery", including inscribing runes on there in your own blood and something known as the "magic jar" spell]

-The other methods Azoch mentioned to me are guaranteed successes, but cannot be considered. If an innocent's life is what is needed to erase the risk of failure, then I'm willing to gamble my soul.

May the gods forgive me.
