Arcane Assault

You are a specialist in combat magic. You gain the following benefits:

Whenever you cast a spell or rune of 1st-level or higher that requires an attack roll and you miss the attack, you deal half damage for that spell, instead of no damage.

Whenever you attack with a multi-hit spell, every hit raises the damage of the next hit by 1. This bonus stacks until the end of your turn.

When you cast a cantrip that requires an attack roll, that require you to roll multiple dice for the damage roll, instead of making only one spell attack, you can split the dice, making one spell attack for each die. For example, a 5th level spellcaster casting a fire bolt could fire two bolts, instead of one, dealing 1d10 damage with each bolt.
