There are two versions of these dungeons. Weak Ruina Station and Ruina Station, Obviously from the name, we are the same dungeon but Weak Ruina Station has adjusted hitpoins, damage, defense and monster drop list for lower level players. So you can experience the dungeon at a lower level and be ready to go into the dungeon when you reach level 75. Weak Ruina Station has been added along with 2 other dungeons (Weak Lake in Dusk and Weak Frozen Tower of Undead) when the old DT Cards (Dungeon Training cards) were removed from the game.

This is the second dungeon you will be able to enter as you progress through the game. If I say you can get good EXP in LID then you will get great EXP in Ruina Station. But you need to be able to go to Invader Mechbuffalos + and unleash your skills on them. I recommend having some nice skills with large damage areas so you can hit many of them at once. If you have some damage and some defense and you’re still around level 80, you can get 1-2 levels per run (30 minutes, LID has 60 minutes). So I recommend you bring someone to the party, get to Mechbuffallos as fast as you can, and stay there until the time in the dungeon runs out. Even if it means not completing the dungeon. As far as I remember with Ruina Station, it is very easy to reach level 100. After level 100, it is better to get EXP in EOD, because EXP from dungeons will be lower as you level up and also the amount of EXP needed to get to the next level is increasing. If you scroll down a bit you will find a video tutorial: how to farm exp on Mechbuffalos+.
Exping
When you level up to Ruina Station here, you may find some inspiration. Use your spear to kill 2 statues at once. Killing more statues will not spawn another Mechbuffalos + (if each monster spawns 2 Mechbuffalos then the maximum is 32 Mechbuffalos + at once). If you kill a statue that spawns 2 Mechbuffalos+ and exactly those Mechbuffalos+ spawned by that tower are still alive, then the tower will not spawn another Mechbuffalos+. You then need to wait 60 seconds before the statue reappears, and only once you’ve killed those + Mechbuffalos will the tower spawn new + Mechbuffalos.
So, before killing the statues, make sure you haven’t left Mechbuffalos + with half Hitpoints, but have most of them killed so you can get new statues.
