Spellblade Training

Through training, you have enhanced your ability to suffuse your martial attacks with arcane energy. While you have a sword in one hand, your other hand empty, and you are not wearing medium or heavy armor, you gain the following benefits:

• When you attack with your weapon, you can use your Intelligence modifier, instead of Strength or Dexterity, for the attack rolls (but not the damage rolls).
• When you attack with your weapon, you can expend one spell slot to gain a bonus to your attack roll equal to the spell slot level spent. Then, if this attack hits, deal force damage to the target, in addition to the weapon’s damage. The extra damage is 1d6 for a 1st-level spell slot, plus 1d6 for each spell level higher than 1st, to a maximum of 4d6.
