You can prepare and deliver deadly acids, granting you the following benefits:

• When you make a damage roll that deals acid damage, it ignores resistance to acid damage.
• You can apply acid to a weapon or piece of ammunition as a bonus action, instead of an action.
• You gain proficiency with alchemist's supplies if you don’t already have it. With one hour of work using a alchemist's supplies and expending 50 gp worth of materials, you can create a number of doses of potent acid equal to your proficiency bonus. Once applied to a weapon or piece of ammunition, the acid retains its potency for 1 minute or until you hit with the weapon or ammunition. When a creature takes damage from the coated weapon or ammunition, that creature takes 1d6 acid damage in addition to the normal weapon damage.
• On a critical hit with a weapon or piece of ammunition with acid applied, you may roll one additional acid damage die and add that to the total damage for the critical hit.
