I like to design weapons for people, but to do so I need to know something about them:

1: The one thing that person desired most in their life. Example: Power, beauty, intelligence, speed, wisdom, height...etc. For me it was power.

2: The one thing that basically embodies that desire. Example: My friend chose power and something else (can't remember). We focused on power and the one thing that resembles power to him the most was vampires.

3: The preferred fighting style of said person. Example: I prefer two-handed swords, but my friend preferred two sword fighting (short sword).

FYI: I prefer not to design modern weapons, due to the fact that I don't like guns all that much. I am like medieval and foreign weapons, such as maces, bastard swords, and katanas. I will update this journal when I decide on the price. Another thing is that if the weapon design if for your character, you have to think about how they would answer the three options.
