Main Hall
Attempting to Adventure Here Before Gaining the Slimeform Disguise:
When trying to adventure here: You make your way toward the large double-doors leading into the main section of the building, but find your path blocked by several large dark-colored slimes, each of which has the word SECURITY painted on its front. From the way they're angrily shaking their pseudopods at you, it seems that they're not willing to start a big fight here, but they're certainly not going to let you through those doors either. You carefully back away before they get any of that stuff on you.
After Gaining Slimeform Disguise:
(Buff is Removed)
Subsequent adventures are combats with security slime. Attempting to adventure again in Slimeform does not result in removal of the buff.
After fighting Lumpy, the Sinister Sauceblob without the legendary epic weapon equipped: A niggling voice in the back of your head (that's me) reminds you that you're heading toward what is likely to be the Final Battle against your Nemesis, and therefore you should probably equip that Legendary Epic Weapon of yours first. Just sayin'.
