Arcane Grace

Summoning a mantle of glowing magical energy you force the Weave into allowing you to twist and bend the rules of magic. Whilst this spell is active you feel the following effects:

• Your spell attack rolls are made with advantage
• When you cast an area spell that affects multiple people, you may choose a number of those people equal to your Charisma modifier. These creatures make their saving throw at disadvantage.
• Whenever you roll a 1 on a damage dice for a spells damage, you may re-roll the die. You must take the second roll. 
• You gain a number of Temporary Sorcery Points for the duration of the spell equal to the level of the slot you cast it at. These points act in the same way that sorcery points normally do - except that after the spell has ended, any points remaining disappear.
