Chaos Dart

You channel chaotic energies into a dart and throw it at a target. Make a ranged touch attack at disadvantage against any target within range. On a hit, roll a d4 to determine the damage type and the damage dice to determine the amount. Any targets hit have disadvantage on all attack rolls until the end of its next turn. On a critical hit, triple the damage dice. On a Natural 1, you take the damage instead.

Random Damage Types:
1. Poison
2. Fire
3. Lightning
4. Healing (Does not affect constructs or undead)

You may throw an additional darts when casting this at higher levels.  At 5th level, you may throw an additional dart. You may throw two additional darts at 11th level, and three additional darts at 17th level.
