They're skills. Ainz, Shalltear, and Narberal all use one or more as does Evileye.

We're never told exactly what the effects are. I'd assume some kind of price must be paid to tack on a skill. As for what that is, hard to really say... There are a few Pen-and-paper RPG examples that come to mind as well as a few MMO ones.
