Mew and the Battle of 1999. Guest starring Mentat
"Charcoal, saltpeter, sulfur. These are the base ingredients for gunpowder in a low-yield form. There are other aspects, compositions, portions...things like that which can change your bullet from 'will not fire' to 'detonates your firearm in the chamber.' Early in your career, you will use magic a lot just to take off. Use it to learn today, so when you are deprived of magic tomorrow, you will have options that aren't 'cast a spell at it' or 'ask magical know-everything familiar.'" Mentat looked over the table for anything he could craft into metal, and smirked at noticing just what he could actually make.
"The casing itself will be important as well, as it needs to keep its shape when the bullet fires so it doesn't damage the weapon...and that's assuming it even holds the material inside, bullet and all. Making a bullet is complex, but not impossible. We need to create the materials for it."
He pulled a vial of mercury from the table, and grinned. "Let's get vulgar, regardless of the warning signs of my newfound weapon, because I don't want to take the time to slow teach you this sort of thing. Mercury is an element of the Mind, which combined with the proper glyphs..." Mentat removes a candlestick from the wall, and blows it out. "Be careful when doing this, by the way: mercury boils away at a low temperature, and this stuff is not curable easily if it gets in you..."
He uses his knife to carve a deep circular groove into the table, and begins etching symbols with the mercury, and some of them are those of the Zodiac. The circle keeps the mercury in one place as he carefully manipulates it. "...but if we do this correctly, we can transmute ignorance into knowledge. Now, pull out one unused bullet, and set it down...away from the fire and the mercury. We aren't ready yet, but when we are, we will toss the bullet into our new improvised quicksilver pool and it will give us a compound which, when mixed with brass or gold, should create an Amalgam that will remember and create bullets of the same calibur you tossed in. They will even have the advantage of being poisonous to whatever is hit by them, so don't use them to hunt, or you will die or make yourself stupid for until a zygote experience."
