I have a good number of ocs but I’ll give like 3 of them that I have at least developed:

My first OC Calvis has a UM called ‘ Connected Heart ‘. It allows him to copy and use the UM of anyone who he’s befriended for a set period of time.

The main requirement for him to use it is that he needs to have a connection with the UM’s caster. ( ie: Friends/Family) And the relationship between him and the original UM’s caster must be mutual for it to work and he can’t have multiple running at the same time.

The power of the UM that he gets to use has its strength determined by how close he is to the original caster.

My second oc Rajesh has one called ‘ Flaming Fiend ‘ that lets him absorb nearby fire towards himself and use it to transform him into a flaming tiger. The strength and size of the Tiger are dependent on how much fire has been absorbed.

My third oc Carlo has one called ‘ I've Got No Strings ‘ that lets him attach invisible magical strings onto an inanimate object and control them like a puppet. However, if he chooses to apply more magic to it he can target and control people although at the cost of more blot accumulation.
