Draconic Infusion

You focus the elemental magic pf dragons into a weapon you are holding. You choose from Acid, Cold, Fire, Lighting, or Poison damage and make an attack with the weapon attack against one creature within it's range. If it is a ranged weapon that uses ammunition the spell creates ammunition reminiscent of the element of your choice. One a hit the target takes the weapon's damage plus 1d4 damage of the damage type you chose, and another effect based on the damage type you chose:

Acid - Each creature within 5 feet of the target must make a Dexterity saving throw or take half the acid damage dealt to the initial creature as the acid splashes out around the target.

Cold - The target must make a Constitution saving throw or it's speed is reduced by 10 feet until the start of it's next turn as ice sets in on the creature.

Fire - The target must make a Dexterity saving throw or at the start of it's next turn it's take half the fire damage it took from the initial attack as it catches fire.

Lightning - The target must make a Constitution saving throw or it can't take reactions until the start of it's next turn as the lighting shocks it senses.

Poison - The target must make a Constitution saving throw or it subtracts 1d4 first roll it makes until the end of it's next turn as the poison sickens it.
