Disturb Earth

This spell allows the caster to loosen a small section of frock or earth to loosen a ceiling, wall or floor. It affects a 10' radius. Caster only has to look at the target and utter the word to cast it, with an optional casting ability at 14th level.

If the spell is cast on a ceiling, pieces of rock will begin to fall on an enemy. All creatures within a 10 radius must make a dexterity saving throw at DC14 to avoid the pieces. Every creature that fails takes 1d4 damage per every 2 levels of the caster. If the creature is casting a spell, they will have to make a concentration saving throw, DC18 with disadvantage, to maintain their concentration. 

If the spell is cast on the floor, the creature must make a dexterity saving throw, DC10 with advantage, in order to maintain their footing. A fail causes it to fall prone, or if running to fall face first on the ground, taking 1d4 damage and ending its turn. 

When the caster achieves 14th level, they gain the ability to use their finger to point and concentrate the spell on a specific area, like joints. This effect will loosen the mortar holding blocks together, cutting in to it like a knife. 

Cast on the ceiling, this will loosen up to a 10' square block causing it to fall on all enemies within the dimension of the block below it. A dexterity saving throw must be made to avoid it, as indicated above. If the save fails, any creature below will take 8d12 damage. No additional damage die are added after this level. Any creature avoiding the block, with an intelligence less than 10, will automatically rage as the same level barbarian for 1 turn.

A small, or tiny, creature receiving 50% more hit points beyond their maximum is considered to be crushed. Death is automatic and they cannot be resurrected by any means. A medium sized creature receiving twice their total hit points will also be crushed, only if their are fewer than 6 creatures who were hit. Another dexterity saving throw can be made to determine if the creature was only partially under the block. If successful, then normal rules applying to unconsciousness and death apply. 

Cast on the floor by a 14th level character, the creature must make a dexterity saving throw, DC14 with disadvantage and negating any advantage they normally have. If it fails, they sink in to the floor 18" and their movement is reduced by 3/4. Rotating 90 degrees takes up their entire turn and they cannot attack. 

If the spell is cast in to a wall, it will provide ammunition for a sling up to 10th level caster. At 10th level, through 13th level, it will produce rocks big enough to throw and cause 1d6 damage upon hitting. At 14th level, the caster can slice the mortar around a block, allowing it to either be pushed or pulled out, if there is sufficient strength to do so. If the caster is closer than 5', they can cut a small hole all the way through a block, allowing a person to see through it, if there is an empty space on the other side. 

This spell may only be used once per day and has no effect on living creatures.  It may, however, be used as an attack against creatures made of stone, i.e. Stone Golem. Damage to stone enemies is 1d4 per level of caster. A critical hit by 14th level, or above caster, using the option to concentrate the spell, will cut the creature in half causing instant death, fi the attack occurs within 10'.

 * I would submit, a 17th level Monk with the Quivering Palm ability would also be able to perform a similar action, although they would have to be in contact with it. They would only be able to loosen blocks, not chip away or put holes through them. I leave this to the discretion of the rules makers and DM's.
