You are a seasoned herbalist and brewer of remedies. You gain the following benefits:

• Increase your Dexterity or Intelligence score by 1, to a maximum of 20.
• You gain proficiency with a herbalism kit, and you add double your proficiency bonus to checks you make with it. In addition, you are no longer required to be a spellcaster in order to create healing potions (but must still have the required minimum level, as per 'Crafting a Magic Item' in the Dungeon Master's Guide).
• Each potion of healing you craft restores an additional 1 hit point per d4 you would normally roll for it. (+2 to standard potions of healing, +4 to potions of greater healing, and so on.)
• In addition to a creature drinking them, all beneficial potions (and antitoxins) you craft have their effects gained on contact, including when they hit a creature when thrown as part of a ranged weapon attack. Friendly creatures within 20 feet of yourself can use their reaction to automatically be hit and affected (as long as neither yourself or the friendly creature are blinded).
