Basic Offensive Magic

A blast of blue-white energy emanates from your arcane focus towards a creature within range.  Make a ranged spell attack against the target.  On a hit, the target takes 1d8 Force damage.

When you hit a creature with the attack made as part of this spell, you can choose to expend a spell slot to deal additional force damage to the target, in addition to the spell's normal damage.  The extra damage is 1d8 for a 1st-level spell slot, plus 1d8 for each spell level higher than 1st, to a maximum of 5d8.

This spell's base damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
