Then, after testing their theory, they discovered another point. The "Sharpening Doctrine" had no time limit.
As long as the other party members who were bound to Holy Kara joined the party, even if the "hitman" happened to be able to kill the final Boss when they venture to a dungeon, they all could enjoy the exp after killing the Boss and received the treasure chest for "clearing" the instance dungeon.
Or, they could enter the dungeon midway and meet up with the "goons" who had entered earlier.
Of course.
The rewards had already been divided equally.
Those who came later would not be able to "reap what they sow". They could only receive the rewards from the next instance dungeon.
Other than that, there were many other details and questions. Everyone also conducted detailed tests to ensure that this mythical-level team's exclusive equipment would not "cheat" them.
