I just stole 5 treasure boxes and ran away from angry gremlin crowd.
Since you don't need worry about profit - you can just pass those unprofitable+heatless depths before basil don't waste your time.
Thats not the only thing that you can do with it, but main one.
Mist really helps in crafting/UV hunt.
You can rejoin party till you find one in basil or further.
And after all - it's like TF2 premium - once you became P2P - you get no limits.
Seperate mist pool (which you get then you bought something) means that you don't need to share mist if you have brother. Or you can just use extra mist for extra UV hunt!
For those who think that you need to play ALOT (24/7 lol) - you can just play more then you have more free time (weekends; evening). Really profitable thingy which erases main game limits.
With new Explorer's pack you get 2 weeks of lift pass and extra stuff for really cheap.
So I recomend to try it for everyone. You will feel real joy of the game.
I did something similar in the Decon zone.
I unequipped all my swords and just used a weak gun. I ran through the Decon zone as fast as I could and avoided all the gremlins, I got all the keys and boxes without getting hit too much.
I have to say it was really entertaining instead of killing everything which just became a lame routine.
