Draw Poison

Draw and refine your own poison with a POISONER'S KIT from creatures that deal Poison Damage. Over a long rest you can extract or refine a number of ounces equal to your proficiency bonus + your DEX or WIS modifier. Your poison now deals 2d6 PSYCHIC DAMAGE, half on a failed Saving Throw. DC = 8 + proficiency bonus + DEX or WIS modifier. A failed save will also cause loss of concentration for 2 rounds.
