(you're halfway through creating the element yourself! you've specified the properties needed to show it, now to make it react with things?)
En anglais:
Name = ALCO Description = alcohol, burns, and evaporates at 100° C. Color = clear green (liquid) State = liquid Flammable = 220 (the flammable property?)
I can't really see a point other than if another property was added: FIGH will walk around instead of attacking STKM once in contact with ALCO for a while, depending on the amount of it.
