Donut's new utility spell — punches a temporary hole through a chosen surface, more useful the higher its level.
Hole is the spell Princess-Donut finds waiting in the saferoom mailbox on the fourth floor — and, notably, she asks Mordecai's opinion before reading it rather than reflexively selling it. It makes a temporary hole on a surface of the caster's choosing; a level-1 hole isn't thick enough to breach most doors, so it needs leveling, but Mordecai and Carl both immediately see its creative tactical potential. Donut had hoped instead for something with 'kick,' like Fireball.
A versatile utility spell with strong creative-tactics potential for the party.
