As a RPG games fan, one shouldn't be unfamiliar with the term 'grind spot', a typical location for the players to, as its names imply, grind for levels.
You know, like the Metal something area from the game where a certain famous hero defeats the demon lord. (T/N - It was actually a censored word 'Me*l', so I am assuming Mc is referring to the metal slimes area from Dragon quest.)
Like other games, <Dungeon Activity> was of course not without its own level farming spot. The name of the said location was <The Tower of Trials>, an allow-for-all Extra Dungeon—from total LV0 newbies to LV90 veterans, there's no restriction in who could enter this Extra Dungeon.
But don't be mistaken though, just because it was allow-for-all doesn't mean it was free-to-enter, one of the reasons why newcomers couldn't take advantage of it in the early game period.
Also, there was only this <Training Hall (Dojo)> which didn't have any restriction on who could enter. I mean, even <Beginner Dungeon> had <LV5> requirement to enter, that's why it was an outlier. Well,having not a single unrestricted grind spot in a RPG game would have been like a treasure hunter without a map. (T/N - Going to use training hall instead of Dojo)
With this, we didn't need to be stuck with the repeated tiresome journey from the beginning so that the new character could become as strong as the main team members.
Naturally, a significant place like this wasn't without its restrictions. In this case, it was an exorbitant amount of QP required. It's not a hyperbole to say players were practically cashing out their QP to Lv.
The setting in <Training Hall> was also significantly different, like a shortcut teleportation circle was available from the get go.
There were a total of 18 shortcut teleportation circles, dividing into multiple ranks of <Rank 1> to <Rank 18>, with the difficulty level of opponents going up with each passing rank—along with the QP amount to pay.
As an example, <Rank 1> opponent ranges from LV0~LV10.
Also, the restriction states that your character's level cannot increase beyond it. (Note that having companions is allowed.)
<Rank 2> ranges from LV10LV20.
<Rank 3> ranges from LV20LV30.
And so on, each being the room for raising the level of respective strength, with the teleportation circle there being to instantly teleport them to their respective rank room. You defeat monsters in those rooms that generously provide experience points, which in turn raises your level.
It goes without saying as well, but both the monsters encountered and the experience points awarded differ depending on the chosen <Rank>.
Following that, the limit for basic job holders was <Rank 8>, with the opponents ranging from LV70~LV75.
From <Rank 9> onwards, the monster level reset again to LV0~LV10, but this time for advanced job holders.
The last of the rank, <Rank 18>, had opponents ranging from LV90~LV100 for advanced job holders. LV100 was the level cap for it.
As for how much they cost, the price is as follow;
