Essence Mixer: You can shape your potion into small, non-harmful effects: reactive sparks, colored vapors, temporary crystallizations, and fluids that change state. Spend 1 Hope and describe how you apply your essence to a weapon or armor. When you do so, you gain one of the following benefits until your next long rest:

• 2 to the damage roll

• 1 to your evasion

Adverse Reaction: When the wearer of an armor infused with your potion is hit, the armor releases a burst of smoke. The attacker has Disadvantage on their next attack roll.

Alchemy knowledge: Your knowledge of alchemy infusions is perfect. Any benefits granted by your infusions are doubled and can stack up to two times on the same object.

Volatile touch: You can trasmute an non magic object into another one of the same size. The trasmutation continue until up to one hour after it leave your touch.

Emergency hardening: If an alley in very close range is hitten you can dash in his direction and touch his skin or his armor and spend 1 hope to have his evasion increased by 1d4 for that attack only.

Resilient Form: Choose up to 3 allies (including yourself) within close range. For the next round, the first time one of them takes damage, the level of damage taken is reduced by one step (from Severe Damage to Major Damage, or from Major Damage to Minor Damage). 

Beyond the Limit: You are able to perform a transmutation on your body or that of an ally, forcing the form into a temporarily perfect state. Spend 3 Hope to completely transform the body of yourself or an ally within very close range for the next five rounds (or until the target is knocked down). The target gains one of the following forms:

• Adamantine Form: The target's skin transforms into metal or stone armor. The target gains resistance to all nonmagical damage types. Additionally, its Defense action rolls gain advantage.
• Ethereal Form: The target's body transforms into vapor or a luminous substance. Its Evasion permanently increases by 2 for the duration. It can move through spaces occupied by opponents and difficult terrain, and the first 5 feet of each movement do not provoke attacks of opportunity..
