Energy blast

A beam of portal energy swirls around your hand, which has 2 outstretched fingers. It can be blasted forward, or built up. You fire it at a creature within range, which takes 1d8 + Your spellcasting ability modifier. Alternatively, build up power, so if you attack with this spell next move, it does an extra 1d6 + double your spellcasting ability modifier. This can stack up to 3 times.
