History YMMV / DungeonsOfDredmor

* ScrappyMechanic: Critical hits are just as susceptible to being blocked or countered as any other sort of attack; they have no priority at all. While this is nice when it works in your favor, it's aggravating to have a dozen attacks in a row met with "Critical hit - but the monster counters it!" It makes critical chance feel like a meaningless stat.

** Fungal Arts adds chances to spawn mushrooms from dead enemies. Because each chance is rolled separately, its common to get at least one or two mushrooms when the skill is maxed. There is a mushroom for almost every ocassion: strength, damage resistance, mana, invisibility... and you can reroll for free stack of mushrooms you don't want. It also provides two powerful pets that cost nothing but cooldown, and summoning either also creates a large cloud of confusing spores to which both you and your pet are conveniently immune, thanks to the toxic resistance provided by the skill. All in all, it's a powerful skill that helps every build.

* CrowningMusicOfAwesome: Most of it, but special mention goes to [[https://www.youtube.com/watch?v=zquJ6AqvVNw Diggle Hell]].

* BossInMooksClothing: Each floor tends to have one particularly strong monster way above the rest, but none is worse than The Great Pumpkinn, who is invisible and thus hard to avoid, likes to roam a lot, summons nasty toxic clouds and hits you for some of the nastiest damage you can find in the first few levels. Speaking of first few levels, he's usually in level 4, give or take a few, so you can bet he'll eat up at least one of your characters.

** Necromancy is meant to have great effects balanced by debuffs and damage after casting... except the damage can be prevented by just a few points of necromancy resistance, and the last three levels of the skill GRANT necromancy resist and have disproportionately small costs for their effect. The fourth skill on a good tank build allows you to survive in melee combat indefinitely and costs next to nothing, and the last skill does huge damage over time to a huge area that'll take out most groups of monsters in one shot in exchange for a few dozen turns of marginally weaker magic.

** Eelys are these early game. They show up in bodies of water and almost alwatys a reasonable distance away from you when you enter their room. They spit powerful acid bolts which can end your run depressingly quick.

* GoddamnBats: Pumpkinns and Witchies can be annoying depending on your setup. Pumpkinns have a high attack and can summon an Area-of-Effect gas over you that, even if it doesn't hurt, it will still drain any buffs that have a hit counter by at least 2. Witchies can blind you if they choose and you don't have high magic resistance, as well as bring back the dead. That being said, neither are too deadly on their own even if you don't have a counter for them.

** According to the Gaslamp Games forums, the Egyptian Magic skill is this, to the point where it's been nerfed by a patch almost immediately after it came out. It still is incredibly powerful though. Thus, some people reported cleaning level 15 zoos with ease.

** Even worse are enemies and traps that can Corrupt your equipment, reducing their bonus to the point of being detrimental to your stats. Special mention should be given to Diggle Archmages, who can Corrupt your equipments at range (others Corrupt at melee range and can be kited around). Make sure to have 100% Magic Reflection when you face them.

* ObviousBeta: Upon release, Conquest of the Wizardlands had more bugs than the rest of the game put together.

* GameBreakingBug: Murderous Rutabagas and their sprite-swapped counterparts used to charge at you several times in succession and give you so many stacks of the Food Poisoning debuff your maximum HP would go low enough for you to die in one hit, which they'd gladly deliver. Fortunately, this was just a bug, which was later fixed.

* GoodBadBugs: [[http://community.gaslampgames.com/threads/the-current-bugs-thread.4118/#post-47893 "Features"]], as they're called, include the generation of items under a shrine square, loss of experience overflow while gaining a level, and spawning multiple zoos on a floor.
