I've been 'skilling' alchemy for quite the time now, felt like submitting a simple idea for a purely RP item as they seem to be lacking. (Maybe?)
Anyway.
Fingers crossed that this hasn't already been made. e_e
Hot Water Bottles, starting with the ingredients/recipe.
Base: Aqua Vitae - Despite this being an RP item, Aqua Vitae would be suitable as actual reagents will be used rather than flowers for tea.
Though, I was thinking of simply using water as this is purely an RP item.
1. Flametongue Root - A Fire symbol (Heat), would be a good start as (obviously) hot water bottles provide the user with heat. (And Flametongue lowers the boiling point in whatever it's being used in.)
2. Blissfoil - A Water symbol (Calmness), would keep the bottle emitting a comfortable/calm amount of thermal energy, rather than overheating.
2.5. Alternately, Serpent Stalk could be used... possibly?
3. Swamp's Blossom - An Air symbol (Quickness), this could be utilized in the making of the bottle via quickening the reaction.
More ingredients could be added, though my thoughts are to keep these at a minimum.
Uses
An RP method of warming up during winter months rather than sitting at the fire.
Re-usable - it does nothing but provide with RP, maybe give it a quick shake to re-use?
A possible addition to medical roleplay?
Possible Drawbacks
Bottle breaking as a result of overuse.
The reaction no longer working because of low skill alchemy or overuse.
Thanks for reading through this submission, please leave feedback, especially if I'm missing something or part is wrong, I'd be willing to read it.
I think this would make a subtle yet interesting addition to the skill, alongside providing with a small amount of RP to play around with.
