I got a bit cheeky in the Missing Caravan quest.
I bought a stack of Blue potions beforehand. When the alarm gets tripped, I parked mysellf just out of the Orkind guards' LOS.
Then threw rocks at one of them until it started the crawling animation. Eventually, the other two raped the poor bastard to death.
Took a long time and a wad of stamina potions but this was fun.
justforlustdoll, Trade Points are just for trading in the current area. They're not physical coins.
So if you leave, they're all gone even if you return to that area. They don't just drop over time.
Otherwise, surviving by slutting would be so so easy.
