Venomous Shot

You fling an arm out from your waist and spring forth a purple blob at a target. If the target fails a CON saving throw, they will be inflicted with the Poisoned condition after three turns if they are not immune or have a way to neutralize the poison. This poison deals a d4 of damage for three turns once the Poisoned condition has taken effect.
