mmm, I have seen the cnr crafting for wands and scrolls, and it does look marvelous.
As for back on topic, alchemist fire. I have always thought that for a better effect there one would use oil or something, ie, soaking ones enemies in oil before igniting them to do 2/3 x more fire damage. I use it in table top a great deal, but not sure how feasible or easily such might be implemented. Maybe more alchemical contraptions from the happy gnomes which are about in barovia, a stronger alchemists fire, which does a bit more than 1-6 dmg on the aoe.
