Went to world 66 because I decided to try law running. I get to the altar, and see people going "law me!" and "open *insert number here*" and "open *number here* no ess back". What does everything mean there? First time trying and it was torture!

first dont say open only noobs say open. next usually look for a high lvl player such as lvl 80+. they should all be standing in the middle area before the rock. dont trade with the people that give no ess back. when you trade someone that says open you offer 27 pure ess and in return you will receive 27 laws and 27 noted ess. leave, bank, repeat
