Charge up

You tense up your body and an aura of your choice of color bursts out, this effect lasts until the end of your next turn, and upon casting another spell you can choose one of the following effects:

You may double the range/radius of your spell.

You may double the damage of your spell.

You may have advantage on casting the spell.

Or an enemy recipient of the spell has disadvantage on any saving throws the spell may prompt.

If casted at 3rd level, you may cast the charged up spell as a bonus action.
