Create Highground

To gain a tactical advantage, you raise the earth beneath you in a 20 foot radius centered on yourself. The ground rises by 3 feet vertically for every 5 feet laterally, reaching a maximum of 15 feet at its pinnacle. If you cast this spell over terrain that is already sloped or not made of natural dirt or earth, the spell fails. Any creature standing on this magically created hill that makes an attack gains a +2 to attack and damage rolls against any other creature that is on a lower elevation. If you maintain concentration for the full duration, the hill becomes permanent, but the bonus to attack and damage rolls fades.

At Higher Levels. When you cast this spell using certain higher-level spell slots, the bonus to attack and damage rolls increases: +3 with a 5th-level slot, +4 with an 7th-level slot, +5 with a 9th level slot.
