Here’s a metamagic I’ve been kicking around for a bit.
Enduring Spell
When you cast a spell, you can spend a number of sorcery points equal to the spell’s level to have that spell repeat itself on one target affected by the spell at the start of the target’s next turn. (1 sorcery point if the spell is a cantrip). The target is allowed all saved and checks to avoid the spell as the spell allows.
Thoughts?
