Ok, this will only work for Anbu and Anbu Captains (the ranks)
You go to the forest at level __ and there is an option:
Anbu hunt.
If you click on it, you are asked whether you want to go on the mission or not. The mission is:
You have encountered _______ who lunges at you with _____!
The blanks, refer to a person that is evil, and was currently in the forest at the time of the mission. This will be totally random. You fight another person, limit levels 3 above and three below, and limit 2 DKs above and below yourself as long as they are in the forest at the time and are evil.
This only works for Anbu and Anbu Captains, and you can only do it once per Dragon Kill. Think of it as a random PvP..
Only easier
;;;
I doubt you could find someone like that though.. I guess it could work if the number of online people in ShinobiLegends is at the max: 130
