Imbuing Ritual (5e Spell)
From D&D Wiki
|5th-level Necromancy (ritual)|
|Casting time:||Must be done out of combat|
|Components:||1000 gold, Blood, Bone, and Flesh of creature you use|
The ritual is fairly simple, you sacrifice some parts from a creature (ex:Dragon). Then, you discuss what qualities you want from that creature with your DM.
