Bleeding Frenzy

When casting this spell you enter a bleeding frenzy.
For the duration of this spell, you get the following benefits:

• Your unarmed strike begins dealing 1d8 + [Your spellcasting stat] slashing damage.
• When dealing slashing of piercing damage you deal an additional 1d6 of that type to targets you've hit before.
• When dealing slashing or piercing damage, you can use your reaction and bonus action to attack as if you had another attack action. (This allows you to get multiple extra attacks if your class gives you those.)

Once the effect ends you need to roll a con save against your own dc or take 2d6 necrotic damage that can't be reduced by nonmagical means.
