Chroma Quaternion is a Role-Playing Game for smartphones published by Kemco and developed by the EXE Create Inc. team, released in 2020. It has you explore four kingdoms with each one corresponding to a season based on the Quadeity that's in it.
This game provides examples of:
- Anti-Grinding: The EXP and Gold you gain from enemies weaker than the team decreases gradually, with the decrease going as low as -50%.
- Bad Liar: Whenever Eara tries to tell lies, they come across so obvious that it can be seen on her face and Ark winces at them.
- Big Friendly Dog: Foure's a dog who's easily Ark's size, but his interactions with him are always genial, and he gets along with other party members too.
- Boss in Mook Clothing: The boss enemies, who look like normal ones but have a red color scheme and are slightly bigger, plus they have much more HP and higher attack.
- Bribing Your Way to Victory: The game has Downloadable Content in the form of multipliers for EXP and RP, as well as one that doubles damage dealt but not taken, each of which can be de- and reactivated in the game's settings once installed.
- Butt-Monkey: Ark gets his fair share of misfortune, like getting tied up and forgotten or hit by a monster just as he arrives in Sama.
- Character Class System: Each character can have up to three roles at once. Every role gives different skills and stat increases. Once a role reaches level 20, it can be refined up to four times to increase its max level up to 100 and provide passive stat increases or new skills regardless of role.
- Crystal Ball: Sharika uses a crystal ball to see visions, like how Otam is going to be destroyed or to see that Eara is the princess of Spree.
- Digging Yourself Deeper: After Eara tries to say she's no one significant, Evaile calls her a princess. Ark has to clear things up.
- Dissonant Serenity: Ark is annoyed with the village mayor not being concerned with the earthquake situation because no one was injured.
- Encounter Repellent: You can use Guardian Stones to halve or nullify encounter rates in dungeons.
- Encounter Bait: You can use Guardian Stones to multiply the encounter rate up to 3x. Or just wear the One-Step Shoes that also provide 100 defense.
- Experience Booster: The EXP treasure multiplies EXP earned after battle. You can have to up to 3 of it for a 4x multiplier.
- Family of Choice: Since people are born from the Quadeity Spring, there are no parents and children. Therefore, springizens who look for such a relationship swear to the Quadeities they'll hold each other dear.
- Foregone Victory: You can turn on the battle shortcut option to win encounters instantly if your level is high enough.
- Fight Woosh: When a fight starts, there's a spiral effect, then you have to sit through a few-second load screen.
- The Four Gods: The Quadeities, with each one corresponding to a season.
- Goldfish Poop Gang: In the Kites Cave, the team runs into the Loosestrife Gang, a trio of bandits who had everything stolen by the Singrette.
- Good Morning, Crono: The game starts with Ark being woken up by Foure.
- Hair of Gold, Heart of Gold: Eara is the blonde princess and she's willing to pay to help dogs to an almost naive extent.
- Health/Damage Asymmetry: Party members deal about ten times as much damage to enemies as they do to them.
- Item Crafting: You can put weapons and armor in a pot to turn them into rings that give its passive ability but not the ATK/DEF boost.
- Jump Scare: In-Universe, Salfad's sudden appearance makes Ark jump.
- Killer Gorilla: Gorillas on surfboards appear as enemies.
- Last of His Kind: At first glance, the world of the game is inhabited by humans; but in fact they are springizens who are born from magical springs. Previously, the world was populated by humans; however, because of the cataclysm caused by divine strife, humans have died out, and to replace them, local deities created springizens. Salfard is the last human in the world.
- Leitmotif: Extermi and Elimi have a distinct theme with a bombastic entrance and a cheerful rhythm.
- Limit Break: The Divine Gauge fills up slowly each turn. Once it's full, a character can summon a Divine Beast to deal giant amounts of damage to the enemies.
- The Lost Woods: The Cocoon Forest is said to be impossible to navigate without the Mentor Sphere. It leaves flowers in the correct direction, as wrong paths either loop or lead to dead ends.
- Magic Music: Extermi and Elimi's role makes their music help others do things, like when Ark tries to fish but his efforts are fruitless, their singing helps him fish it up.4
- Metal Slime: There are some evasive enemies with low HP who tend to run away and drop stuff, with one of them literally called "Metal Slime".
- Mobile Shrubbery: Foure's second role is a disguise as a barrel. He uses it to get into the Coast Storehouse, as Singrette members think he's a barrel they forgot to take.
- Money for Nothing: Enemies drop craptons of money, but they also drop items and weapons, so you often don't need to buy new ones. This results in money only needing to be spent on refining jobs, which doesn't cost much.
- Monster Arena: The arena has three cups with three levels of difficulty each. You have to win three battles with monsters in a row to win Guild Coins.
- Monster Compendium: The Enemy Guide lists the enemies' stats and drops.
- Ninja Maid: Evaile is Eara's maid who has a ninja-like Shadow Figure role.
- Non-Indicative Difficulty: Silver Cup Hard isn't as hard as Silver Cup Normal, as enemies having buffed status makes the fight much more difficult than the inability to use skills, it's really just slower.
- Noob Cave: Twin Hills, the first dungeon you visit as part of the final lesson for the departing children. In an unusual case, you visit it twice not long after the first time, o take Exttermi and Elemi.
- NPC Roadblock: There's a merchant blocking the way early on. He gets stuck between rocks later.
- Play Every Day: You can try your luck at the lottery three times each day.
- Premium Currency: Season Stones that can be spent on exclusive items and weapons. You can earn them as occasionally from battling monsters (though you don't earn them if you use the Battle Shortcut option), completing daily missions, winning them at the lottery, or buying them for real money.
- Pumpkin Person: Some enemies in Otam have pumpkin heads.
- Randomly Generated Quests: The guild gives three quests involving suppression of monsters in a selected area each day.
- Rare Candy: Monsters sometimes drop seeds that increase stats by 1. The exception is HP, which is raised by 10, 30, or 100 depending on the seed type, and Ability seeds that boost all four stats by 4. Later on you gain Flowers that increase stats even further.
- Retraux Flashback: All the in-game flashbacks use a slightly intense sepia tone.
- Sibling Yin-Yang: Salfard's daughters. Extermi is really energetic, while Elemi is more phlegmatic.
- Sympathy for the Devil: Eara sympathizes with the Loosestrife Gang after hearing their story and the fact that they were sharing one cup of soup between the three of them, but Ark is against that.
- Taking You with Me: The attack used by Aim for the Master (the first enemy in the arena's Bronze Cup), Art Is Explosive!, kills it and deals damage to you.
- Undesirable Prize: The two worst prizes at the lottery are a Golden Ore S, with the only purpose for it being the ability to sell it for a measly 1500 G, and a single Guild coin that can be easily earned by beating the Bronze Cup Easy level.
- What's Up, King Dude?: Ark initially apologizes to Eara for talking to her like to a village, but she doesn't mind.
