In Short: (and simple)
Limbus is a zone that is a mixture between Dynamis and a BCNM. Each path inside Limbus plays differently so it’s a little hard to put into words. For example one path requires you to kill hordes of beastmen, another path has you kill common monsters like slimes, birds, etc. There is an even a path where you face some of most fierce HNM’s in the game. The object is simple, you need to collect special Beastmen Coins that is later upgraded for Af+1 (lvl 74 armor). It’s an uncapped event, limited to 18 players, and you are allowed to enter once every 3 days. It’s the perfect mixture of difficulty and enjoyably. Out of 5 runs, I have collected enough treasure to just about upgrade to my Af+1 gloves. I just need 3 more coins, and 1 rare/ex item.
Oh Yea I forgot lol.
In addition to Af+1 if you can't use Kirin Body you can grab the best armor for your job. Stats are below. Getting this isn't really that hard, the Mega Boss that drops this always drops 2-3 parts.
