Spellblade (Charisma)

You've learnt how to infuse your own weapon with the residual mana leftovers from the spells you cast.

- Once you cast a spell you may decide to use the mana leftovers to infuse your weapon for 2 rounds, the damage bonus is 1d8 + half of your spell attack modifier (rounded down) this draws in mana debt equal to half of the original spell's mana debt.
