Unfortunately, there still is in Tibia people using unofficial softwares to play. One of the only ways to counter it is by luring monster or the cheater to a trap where a stronger monsters or a huge mob of monsters can kill him.
However, is that legal? Is that right to lure monsters against other players and do traps? Because at the same time, I know very well that some people are blocking spawns/quest areas with elaborate traps that will kill you instantly, ruining the gaming experience of several honest players... Sometimes these lured traps are similar to exploiting a game weakness/poor design.
What is the recommendation to players that want to lure monsters against others? Lurers are free to do everything they want or not? What is the interpretation that we can get from Tibia rules and determinations by Cipsoft so far? Is it the same rule according to server types (retro open pvp, open pvp, optional pvp, etc)?
