Arcane Arrow

You create a magical arrow made of either Lightning, Fire, Cold, Acid, or Poison damage. The arrow must be fired within the same turn or it disappears. Each element type has a different effect upon hitting a target. Once the arrow hits an object the magic is dispelled and the arrow disappears, otherwise, if the arrow is not fired then it disappears after 6 seconds. This spells damage increases by 1d4 at 5th level, again at 10th level, again at 15th level, and again at 20th level.

Lightning: 1d4 lightning damage, creature can’t take reactions until the end of its next turn. 

Fire: 1d4 fire damage, creature takes half the damage rounded down at the start of its next turn. 

Cold: 1d4 cold damage, creatures movement speed is reduced by 10ft until the end of its next turn.

Acid: 1d4 acid damage, whenever this arrow hits an object or creature all creatures within 5 feet of it must make a dexterity saving throw. Upon a success they take no damage, upon a failure they take 1d4 acid damage. The creature hit with this arrow is unaffected. 

Poison: 1d4 poison damage, creature is poisoned for 10 minutes.
