It's not bad. Knowing you've never played FF makes me somewhat forgiving on this, but it sounds a lot like materia as introduced in FF7. I personally find nothing wrong with the name magicite, though (didn't play FF3). The good/evil stuff seems a little illogical (to me, substances are a media and have no innate good or bad, it is how they are used that determines their worth), but I'll wait for you to flesh that out before judging. Good write up.
The Brute - He will more than get the job done, but don't expect a clean kill. Not a masochist like the Mutilator, this one just happens to prefer killing by blunt force trauma more than anything else.
The Black Widow - Part seductress, part killer. She lures in her prey with her sexuality before killing them.
The Politico - She'll only take jobs that match her political leanings - or, at the least, don't oppose them. Her victims are usually found with some revolutionary pamphlet explaining the murder. These tend to be high profile contracts as well.
The Sniper - His victims never see it coming. An expert at all projectiles - bows, crossbows, darts, javelins, basically anything that can be used from a distance. He is rarely caught due to his distance from the target, but he won't dare take a shot unless he's 100% sure it'll hit, making some jobs more difficult than others.
The Decoy - Not so much a skilled assassin as an average man on the street who knows which end of the knife is pointy. If a large, prominent organization - a government, for example - wants a job done but needs to distance itself from the target for political reasons, a decoy can be hired to do the hit and take blame.
The Shadow - In and out before anyone can see her, this assassin is the definition of stealth. She can leave a mess since she leaves before any clean up can be done, but she is rarely caught. This also makes her very pricey.
The Bomber - An alchemist and sapper, this assassin specializes in explosives. A bomb can be rigged just about anywhere for the right price. He tends to move from town to town, as his explosive calling card is too distinct to stay under cover too long.
The Trapper - A wizard and woodsman, this assassin prefers to set up elaborate traps to eliminate targets. Because of the specialized nature of her work, she tends to only be useful in jobs involving castles or out-of-the-way public places, not house calls.
The Infiltrator - It doesn't matter where the target is hiding, this assassin will get in and make the hit. Particularly useful when a lord or other paranoid locks himself away in a keep or mansion. Some infiltrators have a short life expectancy: they can get in easily enough, but getting out alive is sometimes tougher. Go to Comment
A small band of squirrels seems to be fighting high up in a tree over a shiny nut-sized object. Can you retrieve the prize without scaring the squirrels into running off with it? If they do, can you manage to chase them down?
