Tri-Ele Shot

You brandish the weapon used in the spell’s casting and make a ranged attack against one creature within your weapon's range. Choose one of few damage types: Cold, Fire, Lightning. On a hit, the target suffers the weapon attack's normal effects but deals damage in the element you have chosen. In addition, the target would gain a secondary effect depending on the element you used.

Cold: At the start of the target's turn, they take an additional 1d8 cold damage, then have their movement reduced by half until the end of their next turn.
Fire: At the start of the target's turn, they taken an addition 1d8 fire damage, then they would have their AC reduced by an amount equal to half of your proficiency bonus until the end of their next turn.
Lightning: At the start of the target's turn, they take an additional 1d8 lightning damage, then are unable to use reactions until the end of their next turn.

The spell's damage increases when you reach certain levels. At 5th level, the ranged attack deals an extra 1d8 elemental damage to the target on a hit, and the secondary damage effect increases by 1d8. Both damage rolls increase by 1d8 at 11th level (2d8 and 3d8) and 17th level (3d8 and 4d8).
