I've been watching some of the MM6 videos on YouTube and came across an unlimited food glitch. The difficulty is getting to the dungeon unless you have the Fly spell or Jump spell. I believe gamers called this the NWC Dungeon? Since this works will the unlimited gold and experience glitch for the Hall of the Fire Lord quest work? I don't feel guilty using these to my advantage because I did almost beat the game a few years ago.

You can get to the NWC dungeon even without spells. Just come closer to the Buccaneer's Lair and use PageUp key to aim to its roof, and push Space.

Not only food, but maximum 10000 money and several good items can be found there. Money can be saved if you hire a Town Gate Master.

Yeah, I have found two royal chain mails from the so called dungeon that give me 36 armor for my characters. The best part is that when it replenishes next time, I can sell it. Currently trying to do the Hall of the Fire Lord quest but it's somewhat difficult. I would have been farther f not for another corrupted saved file. That's twice in less than three days the game has gotten corrupted.

I never access the NWC site when I played the MM6 but just watched the video. Is that the same room you access in MM7 from the ocean floor? It's been a while since I played both games to completion but I seem to remember a similar type of area that you get to while completing the game. (Don't what to add a spoiler here for MM7)

It isn't glitch, it is just secret dungeon, which doesn't have anything that special. You get legit way of getting practically unlimited food when you learn "Create Food" spell and get high enough skill level in Light Magic.

What concerns Hall of the Fire Lord, that was indeed bug, but it was fixed in later patches (included in GOG version) together with other good bad bugs (like training all skills on all classes., e.g. getting Plate skill for Sorcerers), unintended experience caps and general instability of the game when your characters have high stats.

Oh there was bug with original version, where you could get as much as 2 billions gold by repeatedly opening Obelisks' chest. Now, that was the bug :) Being another good bad bug, probably these are not bugs and they were in game for a purpose like secret features to get enormous amounts of EXP and Gold, MM 7 had nothing like this, but MM 7 has Well of Wishes, which gives gold, exp and skill points in unlimited amounts.
