Ah I see what you mean, it seems to be the entrance of the Dungeon ;) But there is a hidden door right next to it in the Vines

Hello! You beat Seldarine without the Air Balloon? I would like to know how you achieved this! Also The Hot Air Balloon is obtained by completing The Blighted Grounds and defeating the Blight Queen, as well as helping the Innkeeper in the Pale Fort at the Rust Bucket Inn, he gives you a key to the storehouse which is locked otherwise and you bring the materials from the Blight Queen and the storehouse to the man inside Cryptopia and he should build the Hot Air Balloon Transportation for you to access the final extra area.
I did test that Blight Queen fight and theres actually a error where the Blight Queen's battle picture literally does not go away after the fight so I will need to put out a hotfix for this and maybe add a keybind that can delete all pop ups like that in the future if theres anyone that has it stuck on the screen.
