Chromatic Smite

Channeling the chaotic power of Tiamat, your weapon strikes with devastating elemental energy, dealing extra damage and inflicting a secondary effect based on the chosen element.

As you strike, the wrath of Tiamat channels through your weapon, infusing it with chaotic chromatic energy. Choose one damage type from acid, cold, fire, lightning, or poison. Your attack deals an extra 2d8 damage of the chosen type.

In addition, the smite may trigger a secondary effect, depending on the damage type chosen. The target must make a saving throw to avoid the effect:

• Acid: The target's armor begins to corrode. On a failed Dexterity saving throw, their AC is reduced by 1 until repaired (maximum reduction equal to your proficiency bonus).
• Cold: The target's speed is reduced by half until the end of your next turn on a failed Constitution saving throw.
• Fire: The target ignites, taking 1d6 fire damage at the start of each of its turns for the next 3 rounds unless it uses an action to extinguish the flames.
• Lightning: On a failed Strength saving throw, the target is pushed 10 feet away from you and knocked prone.
• Poison: The target becomes poisoned for 1 minute on a failed Constitution saving throw. It can repeat the saving throw at the end of each of its turns, ending the condition on a success.

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