Im not exactly for this idea, but i might as well help it grow since it is a good idea in the first place. The bodyguard should be customizeable like so:
Level: 45 (Your level)
Dueling level: 47 (your dueling level)
Wep: Sharp machete $108 (should be 1/10th of sale price Rounded)
Stats 1/4, 1/2, 3/4, Full (1/4 is free, 1/2 is $50, 3/4 is $100, Full is $200)
Assign Attributes and Skills: Shows skill select screen with the amount of Skill/attribute points of the person of your level. AKA 136 skill 45 attrib for full.
Confirm price: $308 for 4 hours
I can do a table for all the weps prices if you like this.
