I particularly like to run Maze of Lamth by myself with Hirge since level 8 until I unlock Sunkel Citadel, I know I can't reach deep at level 8, but I usually go until I have used all rest buttons and there's no possibility to go further, then, I use scroll of return after that, I usually earn about 4~6k in one run at level 8 to 9 and 10 to 12 I can basically earn even 10k, I avoid using cure potions or mana potions for Hirge, if needed, I tend to use the less potions as possible, rest buttons are usually enough to earn a good amount of gold, when I need more potions, I go back to the best place to buy them from what I can see so far which is in Freetown in the Grey Library, they offer a good discount, I also tend to sue 2x scroll of experince 7% to increase experience earned for each run, so, gold is not really a problem for me in this game, not even from level 8 to 15 which is the level which I think most players will face it hard to play as many don't know that Maze of Lamth is so good even from lvl 8 to level 16 (which is normally the level I unlock Sunken Citadel) or until I complete sharps of fate quest
