Game: Play Monsters' Den Chronicles, a free online game on Kongregate

AI always skips

126x Exp After Battle
F0 ?? D2 ?? ?? 61 F7 25
F0 ?? D2 24 7e 61 f7 25

Change all 6 results; whatever you change the bolded 7E to is what your experience will be multiplied by after the fight. Don't go higher than 7E though, or the game freezes.

NOTE: After your first fight, you'll be way above the level of the monsters in that dungeon, and will therefore get 0 exp for fighting them. This is solved by going back up the steps to outside, and then restarting the dungeon. The mobs will be generated at your level, and will therefore give a ton of exp again.

20 Pieces of Loot After Battle
F0 ?? D2 24 ?? 61 D6 25
F0 ?? D2 24 14 61 D6 25

Again, 6 results; change the bold number to anything, but since the loot all displays on one line, it's probably best not to go above around 18, or else it'll go off the screen.

Item Hacks (must be entered BEFORE the game loads; let it load once, then reload it again and pause it before the load bar finishes to enter these in)

NOTE: for most of these, keep the number changes to 7E or below.

Give "socketed" items xx more slots

Stat potions give a ton more stats

61 eb 09 f0 ?? ?? d3 66 83 01 24 7E

Edit Equipment Suffixes (NOTE: for most of these, the end stats are tied to the tier of the item. For example, the "of intellect" suffix gives 1 int, but it's actually 1*(item tier). Meaning that if you change the 1 to 126, the end stat of any item with that suffix will actually give 126*(item tier), which is nice. Some of the stats (like starting action) aren't tied to tier though. For most of these, you can change the end hex number to anything up to 7E, but the underlined ones work on percentages, so don't go above 5A just to be safe.
