Battle system

The battle system in OMORI is similar to the combat of the traditional turn-based JRPGs which the game takes inspiration from, with the use of plugins to create additional mechanics to control the flow of the battle, like emotions and follow-ups.

Stats

Most stats remains unchanged compared to the expected behaviour, save from some renames and small differences, as seen below:

• Heart: It's the normal "HP" or "health points" value we see in other JRPGs, it's the amount of health the character have, the character becomes "toast" (the game equivalent of an "unconscious" state) if it reaches 0, except Omori, who if ever reaches 0 heart it will bring up the "game over" screen.
• Juice: It's the normal "MP" or "mana points" value we see in other JRPGs, it's the amount of mana the character have, most skills costs juice to use, the character is unable to use skills that uses more mana than it have. Only the party members use juice for their skills, enemies uses their juice solely as shields when sad, more on that later.
• Attack: Attack works as predicted, it decides the amount of damage most attacks does, with very few exceptions, like Kel's "run'n gun" or Aubrey's "last resort".
• Defense: Defense works as predicted, decreasing damage taken by attacks and skills, note that there are skills that bypass defense.
• Speed: Speed substitute the usual "agility" value we have in other games, however in OMORI it only affects three things: who will act first, some skills formulas and the chances of running away from battle.
• Luck: Luck controls the critical hit rate, each point in luck is 1% critical rate, however, luck does not increase when levelling up.
• Hit rate: Hit rate dictates how often a attack hits or miss, with the exception of Sunny with 75% hit rate, the default hit rate for the party characters' 0%, enemies mostly have 95% hit rate.
• Critical hit: The chance to "hit right in the heart" as the game puts, as stated before, it's a % chance based on flat luck, each point in luck increase critical hit rate by 1%. Hitting right in the heart increase the base damage dealt by the attack by a value between 50% and 100%, if the base damage's lower than 0, hitting right in the heart will always deal two damage instead.

Equipment

Weapons

Weapons are the characters is main form of attacking, granting the hit rate needed so the characters can hit something, the player is only able to change the weapon of the dream world cast, excluding Omori. Each characters use different types of weapons, as seen below:

• Omori uses knives to attack, while Sunny uses the Steak Knife, his own hands or the Violin.
• Aubrey, while in Headspace, uses a variety of blunt-force weapons, such as hammers, bats, and pillows. In the real world, she wields her Nail Bat.
• Kel, while in Headspace, uses various types of balls as weapons. In the real world, he uses his Basketball.
• Hero, while in Headspace, uses cooking and serving utensils, like pans and spatulas. In the real world, he uses his fist.

Charms

Charms are equippable itens shared between all characters, each character can carry one charm, which will grant a variety of different effects, like increasing stats, granting emotions or immunity to it, changing battle rewards, etc.

Battle actions

During battle, there is a set of actions the player can take at the beggining of the turn, these are:

Attack

The default attack option shared with all party members, doing an attack allow the use of follow-ups when pressing the movement keys in direction of a living party member. Attack always have the same formula of doing double the character's attack minus the target's defense.

Skills

Each character have access to a variety of skills that they can use, however only four skills can be used at the same time, including the ability to guard attacks. A complete list of each characters' skills can be seen on their character page.

Snacks

Snacks can restore the Heart or Juice of one or all party members. Certain snacks can also revive party members who are Toast, or applying some buffs.

Toys

Toys are one-use items, typically causing a debuff or emotion. They can be used on enemies, and sometimes on party members.

Run away

As the name suggests, this action is for running away from combat. the chance to escape is based on this formula: [0.65 * $gameParty.agility() / $gameTroop.agility()], in other words, the speed value of all the party members combined, multiplied by 0.65, divided by the speed of the enemy troop. Whenever a failed attempt's made, an additional 10% chance is added.

Battle mechanics

Energy

Energy is a resource gained whenever one of the party members are hit by any attack, the party starts with 4 energy with an maximum of 10 energy, and consume 3 energy to use follow-ups and 10 energy for using the ultimate "release energy" follow-up.

Follow-ups

As stated before, follow-ups can be used after an attack's made and each party member have a different set of follow-ups, it changes as the player advances throughout the game, ranging from level one to three:

Buffs & debuffs

Buffs and debuffs works similar to what is expected in other JRPG, the most common buffs/debuffs, speed, attack and defense lasts for six turns and stacks up to three times, while the uncommon ones, like sno-cone and the release energy buff, does not stack and last till the end of the battle. In order to keep track of all that, the game makes use of several states, one for each tier of the buffs, when a state already applied is applied again, it removes the current tier and gives another advanced tier, for example, using "Gator aid" will give everyone a "defense up 1", buffing again will remove "defense up 1" and apply "defense up 2", and so on, if a buff is already at max tier it will instead just reapply itself.

Below is a list of all major buffs and debuffs.

There are more buffs used by bosses, these are a lot and may be added later on.

Buff	Tier one	Tier two	Tier three
Attack up	Increase attack by 10%.	Increase attack by 25%.	Increase attack by 50%.

Emotions

Hero's emotion guide.

Emotions is a type of state that gives the character some buffs and debuffs, they also give an "element" to their attack that makes it stronger or weaker to other emotions states, with three tiers for each emotion. It follows the following rules:

• Party characters can only have up to tier 2 emotion.
• Normal enemies and most bosses can only have tier 1 emotion.
• Only Omori and some bosses can have tier 3 emotions.

While under the effect of an emotion, the character does more damage to one emotion and take more damage from another, following the pattern that can be seen in Hero's Emotion chart at the side, being angry stronger than sad, which is stronger than happy which is stronger than angry.

* Emotion Resistance: Takes 20% / 35% / 50% less damage.
* Emotion Weakness: Deals 50% / 100% / 150% more damage.

For example, an attack done to a ecstatic foe from a angry source will deal 65% damage, while an attack done to the angry foe from an ecstatic source will deal 200% damage instead of 100%.
