Exarion's Raise/Move Mountain

Casting this spell is an extremely taxing process. The caster gains two levels of exhaustion immediately as the spell takes effect. In order for the spell to work, there must be a solid layer of stone at most 2,000 ft. below the targeted surface. If this condition is not met, the spell does not take effect, the caster still gains points of exhaustion, and the spell slot is wasted.

Raise Mountain. As you cast this spell, choose a point within range. A mountain up to 15,000 ft. high, or up to three mountains up to 5,000 ft. high, rise from the ground.

Move Mountain. If you cast the spell while targeting a mountain, you can move that mountain up to 1,500 ft. in any direction, including upwards and downwards.
