I'd like to propose the following alchemical recipes for possible quality of life improvements:
1. Liquid fire: Can be used on a flammable source to light it on fire. (essentially a replacement for firebrands)
2. T(h)ermite: Sprinkle on a log and light it on fire to destroy the log. Considered vandalism for the sake of crimes.
And potentially the following, although these can probably be abused one way or another:
3. Debilitating poison: This + any arrow(?) -> debilitating arrow , which slows any non-player entity by x% (for a time? until it despawns?) when dealt damage (has to pierce armour)
4. Aggravating poison: This + any arrow(?) -> Aggravating arrow, which speeds up any non-player entity by x% (for a time? until it despawns?) when dealt damage (has to pierce armour)
