Brief bug summary: Teleporting in and out of Kritias will not work in GMS, but it works in every other version (KMS, JMS, CMS, TMS, and MapleSEA).
More details:
When using a Hyper Teleport Rock to teleport to Kritias (except the Town Hall, which will work fine), you will be given a message stating "Unable to approach due to the force of the ground). If trying to teleport around while currently in Kritias, it will not allow you to do so either, whether you use a Hyper Teleport Rock or the Maple Guide. The only form of teleportation that works is skill based (for example, Cygnus Knight's Imperial Recall skill.) Again, the reason why this is a bug is because GMS is the only version that has this issue.
I have recorded a video for reference:
Steps to reproduce:
Outside of Kritias
1. When outside of Kritias, use a Hyper Teleport Rock and attempt to teleport to a map in Kritias (except Town Hall). Note that you will get a popup message as mentioned above.
Inside Kritias
1. Head to any map within Kritias, except the Town Hall.
2. Use a Hyper Teleport Rock and attempt to teleport out of Kritias; you will receive the popup message.
3. Use the Maple Guide and attempt to teleport out of Kritias, with the same result.

Black mage badge being an argument is wrong. It's not even bis.
Tell that to Nexon Korea, who created it as a drop from the Black Mage in the first place. You would think that they would make a badge dropped by the strongest boss in the game better than it currently is.
Pottable badges were restricted due to orders from KMS not wanting us to have better badges than the KMS meta. Why go for the Black Mage badge when we have Ghost Ship Exorcist, and all that. I agree that it was a poorly thought out decision, but honestly the only way I see them returning is if KMS makes them the new meta.
On a separate note in regards to the new Familiar System, I would love it if the drop rate tables could be included. They were a great resource to have when editing the wiki, and not having them is demotivating when it comes to adding drops for monsters.
