I wonder if by tabletop rules Sorcerer can use Metamagic to any spell they are casting, or if they need to use their own.
For example ... if i cast Ray of Sickness using Staff of Crones ... can i improve it by Twinned Spell?
Can't find a link but read somewhere that Jeremy Crawford, lead rule designer at WotC, allowed it a couple of years ago. But might have just been false rumors.
Niara, no one here knows the ruleset better then you. Any idea?
