Pot consumption.

I get it. Hes boycotting NLC and there is nothing wrong with that.

Anyways your pot costs maybe high but thats not a reason why you cant train alone. Maybe if you learned how to distance yourself from monsters just enough so you dont get hit by physical attacks, you can reduce the overall damage done to you. Also, max jump can help you jump over monsters when you are assaulted by mobs on both sides. Also take advantage of ladders and ledges to help dodge damage.
