Dart Shooter

Thanks to persistent experimentation and resilience, you have modified your forearm and gain the following benefits:

• You can load 3 darts into your wrist shooter as an action.
• As a bonus action, you can fire a loaded dart. When you attack with a dart in this way you ignore the range penalty.
• A number of times equal to your proficiency bonus per short rest, you can fire a modified dart as an action. You choose the effect when it fires: poison, sleep, charm or fear. If the attack hits, the target suffers normal weapon damage, and must save on a DC 12 constitution saving throw or suffer the additional effect.
