Ring of spell storing says:
Any creature can cast a spell of 1st through 5th level into the ring by touching the ring as the spell is cast. The spell has no effect, other than to be stored in the ring.
Twinned spell says:
When you cast a spell that targets only one creature and doesn’t have a range of self, you can spend a number of sorcery points equal to the spell’s level to target a second creature in range with the same spell.
Can I use metamagic to cast a twinned spell into the ring, (meaning anyone can cast that spell twinned out of the ring) and if so are there any additional restrictions?
