Blink? Teleport? Stealth? Cheat? Please check this out

Hello guys, I'm here to ask/report about "something" new for me (maybe for you too)

Here's the thing, my friend suddenly became so lousy at our Linkshell about someone being invisible or something, I think he's just on his first time seeing crafter stealth mode (or whatever it is), and eventually my huntlog was at his map, so I asked him where he is, and I see "this" guy farming Banemite with that "style"..
that guy is a monk, and.. i don't think he's using Shoulder Tackle, because he also disappeared suddenly and already far ahead of us.
You can check on the vid.

Suspect : Tatsuma Jr
World : Masamune
Map : Fallgourd Float

Dunno if I lack of knowledge or maybe it's really a 3rd party or some cheat engine..

That's a bot...

Normal players cannot teleport from one enemy to another...

I've seen teleporting bots too.

omg that's so fast :O shoulder tackle can't be that far >.> nah already report him as cheating ? I'll help report after maintenance then :)

Yes, it's a bot. Report in-game. This thread will probably just be deleted.

Greetings Folks,

We appreciate you taking the time to report this concern you are having to us. However, as stated by the other users, this sounds like an issue with a player hacking rather than a bug report. We welcome you to file a GM ticket in order to seek a resolution.

Good luck and have fun!
