ToME: the Tales of Maj'Eyal

After adding new egos/unique items/vaults/unique monsters, is there a way to quickly see how the contents appear in the game?
Guess this can be at least partially achieved by debug mode, but don't know exactly how to use it.

Unique items can be spawned on command via the lua console. So can specific uniques. I'm not sure if specific egos can be or not. I think the relevant page on the wiki about debugging lists the lua commands you'd need, but I could be wrong, I seldom use the wiki.

Developer mode is meant JUST for that. Turn it on - but remember to turn it off when you want to load 'regular'savefiles or they will be ruined - and then call up the debug menu(CTRL+A by default I think).
