Nature of Elixir

After all those years of searching, inspecting, working, and creating poisons and potions, all the godly energy you are exposed to, consumed... What it should be destroying anyone normally, but 2 minds, 2 souls, 2 will... You adapt and conquer the power, and you put everything into your research. You know the nature, the nature of gasses as a result of using inhaled poisons, the nature of liquids from potions, how they interact with solid objects, with living things, and with each other. You are now the Goddesses of Elixir.

Prestige 2 (Works everywhere):

1. Philosopher's Stone Secrets: As an action, you can touch a liquid or solid substance and transmute it into another substance of equal volume. This could include but not limited to turning water into a potent potion or poison or transforming a mundane metal into a rare alchemical reagent. (This includes creating a potion/poison or any crafting material but can only be used once per irl day this way). Being able to use the materials efficiently, you have an advantage for the rolls for crafting or using such things and you need 1 less crafting material for each different type of material for crafting (except unique crafting materials).

2. We Are One, As We Are Not: Yao and Chao have individual action economies. As an action (separately), Yao and Chao can enter soul form and inhabit willing creatures. While inhabiting another creature, they can not be targeted or affected, but are limited to poisons, potions, and soul-contended actions. If the host becomes unconscious, the soul can take over using its own stats until the host is no longer unconscious. Both Yao and Chao can act on other creatures' turns and try to possess unwilling creatures (WIS save, fail = 1-minute possession, and the soul must use action each round to keep posses. The Creature can roll save again at the end of the minute). Souls can reunite (pulling either soul) within 30ft or completely at will, ignoring obstacles, barriers, planes and such.

Prestige 4 (Works in native realm and realms with roots):

1. Role Change: As an action, you can create an elixir (counts as both potion and poison and can be in any form) that reverses healing and damage effects. Registered creatures take damage when healed and heal when damaged for 1 turn. You can only have a number of this elixir equal to your proficiency bonus at a time, lasting 24 hours.
   
   

2. The Bonds We Made:
   Just like Chao and Yao's souls are connected, you can connect other souls. While connected this way, Chao and Yao know the true intentions of the creature since souls do not lie, can read thoughts, see memories, and understand if the memories are altered without any harm. This ability bypasses immunities against mind-read effects such as "mind blank" spells. Creatures of Chao/Yao's choice can use another connected creature's senses, know their exact location and can communicate telepathically as long as they are in the same plane of existence with Chao and Yao.

Prestige 6 (Works in parts of the native realm):

1. Twin Waves:

   As a bonus action (separate for both souls) a soul wave formed from Yao and Chao, up to 1000ft from each.

   • Chao's Wave: Allies' weapons are coated with poison; enemies hit by the wave must make a constitution save or inflicted by Chao's selected poison and be poisoned.
   • Yao's Wave: Allies receive the effects of a chosen potion; enemies failing a CON save against your medicine check become unwilling to fight and seek peace or flee. If neither of these options are impossible to choose, they have disadvantages on their attack rolls, saves, and checks for 1 minute.

2. Chemical World:

   • Chao: All poisonous plants and damaging effects of your choice are double their efficiencies. Non-magical plant life dies around you or if it's magically strong, their effects are suppressed. The creatures of your choice are under poisoned condition. The structures and constructs begin to abrade, making them break or otherwise not work properly (for constructs, taking away either their actions, bonus actions, reactions, or legendary actions, they are unable to use that feature per turn). The clouds gather as they rain acid, corrupting anything they touch.
   • Yao: All herbs, chemicals, and healing effects of your choice are double their efficiency. Plant life can grow better around you, and curses and diseases or such things can be cured with your will. The creatures of your choice are counted under Aura of Life spell effects. The structures/buildings and constructs begin to mend, making their abraded parts fixed. (for constructs, they take less damage equal to your Charisma modifier per instance of damage). The natural conditions of places such as storms, wind, snow, or similar, their effects on others' are suppressed, and they are removed as much as possible from the affected area.

Prestige 8 (Works in a domain or with explicit DM approval):

1. Experimental Elixir: As an action, attempt to create a potion/poison with any known or new effects. For unknown effects, roll a percentile die (33% failure chance). If it fails, you can not attempt to create that same elixir until you take a short or long rest. DM may decide outcomes regardless of the roll.

2. Determination: Your souls become one with the nature of elixirs, and no longer count as being in a planar realm as they are no longer affected by effects or such. Each time a soul would die, you gain a charge of Determination and the soul gets into an essence state for an undetermined time as long as they want to. While in this state, from the point of the dead soul to 100ft, the surrounding environment changes according to the nature of that soul, changing the material structure and such, as well as healing the allies for 10d10 or damaging enemies for 10d10 poison damage (correspondingly with the soul) for each turn the soul stays dead. If both Chao and Yao dies, each can revive separately by using 2 of the Determination charges for half of their original max hp, increasing the max hp to this amount if was lower.
