RDM only needs to get Immanence and Occult Accumen from SCH for things to be fine. SCHs wouldn't care since they don't use them anyways. I swear people don't ask for Immanence because they don't even know what it is, since it's not used.

Regen would be nice, but honestly RDM doesn't need it. Proper use of Stone skin will save you from anything that Regen could have been useful for. I would take Regen III or IV, but it's not something I can live without. It's party applicable for extended events, but not anything like VW.
