Pictured above is your standard "smash n' grab" mugging, wench style. In this instance, we lure the target to a secluded place, and convince him to remove his armour and weaponry - ripe for a robbing. In this case, i distract the target whilst tammy has moved round behind him, and gone for the purse.
A few ooc pointers about this - power emoting is a strict no no. At no point should you be *removes all of his armour and weapons leaving him defenseless*, or *hits him over the head and knocks him out cold*. These are terrible power emotes, and give the other person no room to roleplay, and its basically just not fun. Instead give the other person a chance - they can either go along with it, fight back, or try and make a run for it. In the latter two, attacking would then be acceptable, since theyve made the decision - not you.
This is just one example of how you might roleplay mugging someone, you dont have to follow this formula, but it can be a change. It gets a bit frustrating for people when there are endless bandits shouting "gimme your gold!" and then attacking straight away.
Be creative, and have fun with it!
