In preparation of an upcoming Update to the Equipment of CT and the high amount needed Items of said Tower, I would like to make an special suggestion today:

First of all, with this suggestion I also ask that both Endless Tower and Endless Cellar are being taken out, cause from an Lore Standpoint, both got taken over by Beteleuse and should not be available anymore.

Suggestion:
Every 5 Level an MVP will spawn, which is random and can be any current available MVP (No Instance MVPs of course) // So no more MiniBosses anymore

2. Suggestion:
After Level 25 you can choose to end the Tower and Fight Naght Sieger, if you want to, you can continue the Tower to Level 50 and then Fight Betelouse // AFAIK you can fight both Mvps only when u reached Level 50 and thus taking out the reasons to fight Naght SIeger cause he doesnt give as much Rewards as Betelouse does. (For CT Gear and Enchantment you only need Betelouse Items, so no reason to fight Naght Sieger)

3. Suggestion:
Once you killed Betelouse on Level 50 you can go to the Throne and talk to an NPC to continue your Journey and climb the Tower 100 more Levels! (Not only 50). Each Level spawns random Mobs and each 5 Level spawns random MVP like suggested above // Like an Endless Tower scenario
At the 151ths Level you can fight against an Betelouse HARD which got 2x the Stats he does on his normal max enchanted status. If you win, you will get 15 Random Treasure Boxes (On lvl 50 you now get 10 on max stats)

4. Suggestion:
Once you killed Betelouse on Level 151 you can now go another 50 Level higher (with random mobs and mvp once again) and on the last Floor 201 you will fight Betelouse ULTRA which got 3x the Stats he does on his normal max Status. He also learns Gantanbain to counter LP. When you defeat him you get 15 Random Boxes like before but you will also get 5x of each Meteorite Fragments (Agile, Power, etc).

5. Suggestion:

Change the Cool Down Time to 12 Hours (Is lower now)
