Some of the achievements in LoT2 seem really a bit too much.
>Someone in the group reaches Lv 1,000
>Play time breaks 256 hours
>Win 10,000 battles
>The number of "infinite jewels" handed over to Akyuu exceeded 100
>Perform status improvement in the magic library 100,000 times
There is also stuff like getting every sub equipments or getting the data on every single enemy.
