[Feature] Ghetto Recipe: Smoke

[Rain2025]

Adds a new "Semi-secret" Ghetto Chemical Reaction to produce a smoke effect. I won't reveal the components because of the desire to make this a secret chem but suffice to say you can make this concoction using just everyday materials you don't need chem/botany access to get. Requires 100C Heating of Said Chemicals in order to produce effect. (Code Name: "Anime Smoke"/PR Name: Ghetto Smoke)
