Can you use the sorcerer's Metamagic option Extended Spell more than once on a single spell? In other words, can you pay more SP to extend the duration by one factor?
Say a given spell has a duration of 1 minute. If you spend 1 Sorcery Point, the duration changes to 10 minutes; spending 3 SP changes the duration to 1 hour; 4 SP makes it 8 Hours; 5 SP makes it 24 hours. Does this work?
