Metamagic is in the game, it's a Sorcerer class feature. You use Sorcery points to fuel Metamagic.
1. Heighten Spell: Gives the target disadvantage on the saving throw of a spell you cast.
2. Distant Spell: Increase the range of a spell.
3. Careful Spell: Makes allies automatically succeed on the saving throw of a spell you cast.
4. Empowered Spell (Not in the game yet): You can re-roll damage dice equal to your Charisma modifier.
5. Transmute Spell (Not in the game, added in an expansion book, may never be in the game): Alters energy type, but you can't choose force.
The game also has Quicken spell,Twinned Spell, and at least one other Metamagic, I can't remember at the moment.
