Metamagic Feat: Bound Spells

Note that this feat is only useful for sorcerers.

You can combine two spells of 1st level or higher, and cast them at the same time, however, the following requirements must be met in order to cast them at the same time.

• The two spells must have a casting time of 1 action.
• Only one of the spells can be concentration.
• They cannot be the same spell. 

The number of sorcery points you need to spend in order to do this is 1+the combined level of the spells.
