- Awesome Music: The entire soundtrack is amazing mix of various styles and genres. Special props to having an option to switch the in-game soundtrack to Re Traux chiptune versions.
- Breather Level: Heaven areas in Cladun x2's Trigeon. While technically possible to stay there indefinitely, you're more likely to be there for only two or three floors in a row before getting sent down to Chaos, or worse, Transitory.
- Character Select Forcing: The first boss, Attack on Orochi, in Sengoku is an extremely egregious case of this; for whatever reason, it has insane resistance to physical attacks, which means anything you do with a melee weapon will only deal as much as scratch damage, and it spews fire at close range, preventing you from getting close anyway. The only way to beat it is to circle around and hack away at it for a few minutes until it keels over, or bring any Rod and turn it to mush in 30 seconds.
- Demonic Spider: Immortals in Cladun x2. Almost completely unkillable (and even if you have the means incredibly difficult), swarm the later areas in Trigeons, deal massive amounts of damage, some move incredibly quickly, can phase through walls and can see you from across the room. Being chased by 7+ Immortals is not a fun feeling to experience, especially with the eerie humming sound they make when they advance.
- The plot-based boss enemies also usually come back as random enemies in the Rangeons, making life much more difficult since while their attacks are powered down, they're still far more powerful than normal enemies.
- The Divine Excess Magic Circle in Cladun x2 is generally not suited for heavy-duty postgame work due to its no-healing-allowed attribute, but apart from that it's revered with the playerbase for allowing a characters' stats to grow exponentially higher than almost any other Magic Circle there is.
- Many Widened skills can become this. Kudos to Heaven Slash, which is an incredibly powerful sword skill in its own right but can be given an artifact that reduces its casting level to 10% of the normal, making it spammable.
- The little-known 10% Bless tactic. Almost all spells are affected by casting level, and presumably Bless is too, but since all it does is inflict a status on the caster (Bless) that heals for a flat 50% health over time, it's incredibly easy to slap an item that reduces the casting level to a fraction of the normal amount and suddenly trying to heal back up to full health is incredibly easy and losing health is suddenly unproblematic. Unless you're using Divine Excess or another Magic Circle you can't heal, in which case this trick does nothing.
- Widens and Growth Artifacts. With judicious use of Widens it's very possible to get your main character's Attack, Defense, and SP stats up to an innate 999, especially when helped along with the Ranger's Crazy Magic Circle in Cladun x2.
- High-level artifacts with amazing titles in general. The first Hiyoseal, *1k, *10k, or Infinite artifact you find will be game-changing.
- The infamous Title Cut 72 strategy, which involves pumping up your equipment with Fortune titles (increases drop rate) and Bliss titles (ends up making equipment only drop with better titles than the baseline titles) in order to make it so that your base drop rate is through the roof and all drops will either have no titles or incredibly good, beneficial ones.
- Sengoku introduces a new Title called Shinobi Step, which prevents Traps from activating as long as you're walking. This effectively cuts the game's difficulty in half, as you no longer have to worry about being killed by anything you accidentally step on, provided you stay away from the Run button.
- Goddamned Bats: Many players have a least favorite enemy that, while annoying and aggravating to fight against, are not terribly dangerous. The squid enemies and the wisps who can inflict status conditions that make you heal them are some popular candidates.
- Nightmare Fuel: In a jarring contrast to the lightheartedness of Cladun X2, If you step on the hidden "Doom Gate" in the Ran-geon, sirens blare and Evil Laugh greets you.
- The bad ending in x2note is actually fairly terrifying.
- Polished Port: Issues with full screen display aside (where in some PC it flickers, forcing the player to play in windowed, thankfully the window is resizable), Cladun X2 PC port is a superb port, with surprisingly low system requirements, highly customizable controls, and support to older Direct Input gamepads (where it display number buttons instead of XYAB that become X Input standard)
- Porting Disaster: The PC version of Sengoku came out horribly bugged, ranging from minor graphical glitches to game crashes. There's also the fact that keyboard prompts not displayed, opting to display X Input only. It has since been fixed though.
- Tear Jerker: Some of the bad endings are actually quite tragic. Examples include Souma choosing to abandon Pudding, dooming her to certain death by the Laughter Disease, Pudding losing everything she ever cared for to alien invaders, and Sunday, Sherbet, Coco and Asagi each getting a Fate Worse than Death.
- That One Attack: Parchmin's ridiculous dragonbreath attack strikes an absolutely massive radius, making it nearly impossible to dodge if you're in the general direction of where he's aiming it.
- That One Level: Lower-level Transitory floors are swarming with Immortals and also infested with nerfed versions of Treants and Golems - both of which have very long-range attacks that can be spammed if they initially see you walking by. In fact, it's not uncommon in later floors to be fleeing to Chaos from Transitory, even when Chaos is built to be one of the toughest areas in the game.
