Door Jam
Potion, uncommon
This little jar contains 1d6 + 1 servings of jam. If you smear a single serving on a door, it jams shut and requires a DC 20 Strength check to open. If you break an empty jar on a locked door, the door pops open and becomes ajar. It can be found in various flavors.
Potion of Clarity
Potion, uncommon
After you drink this potion, during the next hour, you can reroll one ability check with advantage. You choose to do so after the roll is made but before the DM declares whether it succeeded or failed. This cyan liquid is always cool and refreshing, and tastes like fresh water.
Smarmalade
Potion, uncommon
Each jar contains 1d4 + 4 spoonfuls. When consumed, one spoonful grants proficiency on Charisma (Persuasion) and Charisma (Deception) checks for one minute. If you are already proficient in the skill, you instead gain double your proficiency bonus.
Vial Of The Enduring Self
Potion, uncommon
You are protected from diseases and magical effects that alter the body for four hours after drinking this potion. For example, you cannot contract diseases like Lily Spots even after being exposed, or be altered by a polymorph spell, change sex spell, or a magical item that would alter your physical form, even if you do not attempt to resist the effects.
Physical and magical wounds can still be inflicted on you, because they are causing damage to the body, and not merely altering it.
In addition, nothing can be taken from your body. Cut hair, shed sweat, drawn blood, or any other bodily fluid or substance will vanish after parting with your body.
