thank you! the new dungeon sounds interesting… but i need someone to create the scripts. i can add required things on C++ side, yet creating dungeon scripts is something completely different. i cannot even imagine how red_kangaroo managed to pull off that trick without any tools better than text editor.

but i like the idea, and maybe one day i'll try it.
the staff is easy to do, and we can give it to Izzy as unique weapon instead of boring plain enchanted staff.
as for belt of levitation… i simply don't feel it right. besides, the belt is relatively easy to obtain (there are at least 3 ways to get it). checking distance to the nearest land square is not hard, the code could be done in 5 minutes or so. the belt has hella lot of uses already. but… your reasoning looks legit too. if the player wants to fly all over the world… why not?
the devs wanted to make worldmap not as dull as it is now. maybe add some random encounters, in Fallout 1/2 style? not just fights, but some unique events, like those Knights with The Holy Grenade in Fallout.
as for the bomb… k8IVAN has "Hell's device", which was intended to be The Nuke that devastates whole cities. i planned to put it into Alien Vessel dungeon. no specific quests for it, but you can bring it to Attnam and blow it away just for fun of it.
