Crystal Dash

A ring of crystal gemstones appear around your feet as you’re magically propelled in a direction, you choose which gemstones appear when you cast this spell. You move up to 30 ft. in a straight line in any direction, this movement does not provoke Opportunity Attacks, ignores Difficult Terrain, and can carry you across liquids provided you do not end the movement on them.

A creature within 5 ft. of you directly to your side when you move must make a Dexterity saving throw. On a failed save, a creature is pushed up to 10 ft. directly away from you and takes 1d8 damage depending on the gemstone chosen. On a successful save, a creature takes half as much damage only. If a creature intersects the line you move in, you stop early when you reach the creature’s space, and that creature takes the spell’s effect but only reduces the spell’s damage on a success.

List of gemstones.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, increase the gemstone damage by 1d8 for each slot level above 2nd.
