Battle system

The battle system in OMORI is similar to combat in the traditional turn-based JRPGs the game takes inspiration from, with additional mechanics that change the flow of combat, such as emotions and follow-ups.

Stats

Most stats in the game mirror typical RPG stats, save for some small differences, as seen below:

• Heart: Heart is the amount of "HP" party members and enemies have. If fully depleted, the character becomes "Toast" and will be unable to fight.
• Juice: Juice is the amount of "MP" party members and enemies have. Most Skills costs Juice to use, and party members are unable to use Skills that require more Juice than what they currently have. Enemies do not use Juice for Skills, and instead use it for damage reduction when they are inflicted with Sadness.
• Attack: Attack decides the amount of damage most attacks do, with a few exceptions.
• Defense: Defense works as predicted, decreasing damage taken by attacks. Note that there are Skills that can bypass defense.
• Speed: Speed works like an "agility" value, affecting the turn order and the chance to run from a battle. During speed ties, the party leader will move first, followed by the order of Omori - Aubrey - Kel - Hero, then finally, the foes.
• Luck: Luck controls the critical hit rate. Each Luck point equals +1% critical hit rate. Luck does not increase when leveling up.
• Hit rate: Hit rate determines whether an attack hits or misses. The default hit rate for all party members is 0%, with most weapons granting +100% hit rate. This can be changed with status effects.

Equipment

Weapons

Weapons are the characters' main method 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, except Omori. Each character uses 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.
• Basil uses Garden Shears to attack.

Charms

Charms are equipable items 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 the battle, there is a set of actions the player can take at the beginning of the turn, these are:

Attack

The default attack option, shared with all party members, doing an attack allows the use of follow-ups when pressing the movement keys in direction of a living party member.
The basic attack always has the same formula of doing double the character's attack minus the target's defense. All basic attacks have the default 20% damage variation and can hit right in the heart, basic attacks from real-world party members can't hit right in the heart.

Skills

Each character has access to a variety of skills that they can use, however only four skills can be equipped at the same time, including the ability to guard attacks. Below is an abstract for each character's skills, a more complete list can be seen at the character page. Keep in mind that every skill that applies emotions and buffs can be applied again to increase the tier. Like attack, all skills, with very few exceptions, have the default 20% damage variation and can hit right in the heart, skills which this does not apply will have it written on the list below. Unless specified, all enemy skills cost 0 .

Snacks

Snacks can restore the Heart or Juice of one or all party members. Certain snacks can also revive party members who are toasted or apply 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.
Something important to note is that this value is static. One can not speed their team up or slow their enemies down to increase the odds of escape.

Battle mechanics

Energy

Energy is a resource gained whenever one of the party members is hit by any attack, the party starts with 3 energy with a maximum of 10 energy, consuming 3 energy when using 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 has 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 work similar to what is expected in other JRPG, the conventional buffs/debuffs, speed, attack, and defense stack up to three times and last for six turn, or till the end of battle or till the user becomes toast on console versions. Non-conventional buffs and debuffs, like Sno-Cone and the release energy buff, do not stack and last till the end of the battle or till the user becomes toast. 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 or debuff is already at max tier it will instead do nothing and not refresh its duration.
Lastly, keep in mind that both the debuff and the buff can exist at the same time, so, for example, a character can have both the defense up buff of any tier and a defense down debuff of any tier.

Below is a list of all major buffs and debuffs. There are more buffs, which are used exclusively by enemies, like increasing hit rate and such, these are covered when needed on their articles.

Emotions

Hero's emotion guide.

Emotions are 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 emotional states, with three tiers for each emotion. It follows the following rules:

• Normal enemies and most bosses can only have tier 1 emotion.
• Party characters can only have up to tier 2 emotion, and can only have the first tier of afraid.
• Only Omori and some bosses can have tier 3 emotions. Omori is also immune to afraid.
• Sunny can only be afraid, stressed out, angry and sad, other real-world friends follow the same rules as their dream world counterparts.

While under the effect of emotions, the character does more damage to one emotion and takes less damage from another, following the pattern that can be seen in Hero's Emotion chart at the side, which is:

• Angry is strong against sad.
• Sad is strong against happy.
• Happy is strong against angry.

The emotion resistance and weakness values are as follows:

* Emotion Resistance: Takes 20% / 35% / 50% less damage from the weaker emotion.
* Emotion Weakness: Deals 50% / 100% / 150% more damage to the weaker emotion.

This value varies depending only on the defender's emotion tier. So, for example, if the attacker is ecstatic and the defender is angry, the attack will only deal 50% more damage, while if the attacker is angry but the defender is ecstatic, the attack will deal 35% less damage.

Boss specific emotions

Bosses that have advanced tiers of emotion, these being Sweetheart, captain Space Ex-Boyfriend and the Unbread Twins, use different emotion trees compared to the player once they become emotion locked, it follows slightly different rules, as seen below:

Sweetheart

HAPPY	EFFECT	ECSTATIC	EFFECT	MANIC	EFFECT

Increase defense by 50%, decrease speed by 50%, 100% of all damage taken is done to instead, emotion resistance/weakness remains the same as sad.

Plot Armor

After triggering Plot Armor.

When taking an actual killing blow.

Plot Armor is the internal name of the mechanism that prevents Omori from taking mortal damage once per battle. When triggered, Omori's color scheme will temporarily invert, and the game will announce that Omori "did not succumb." Once triggered, plot armor's invulnerability will not be removed until the end of the turn: Even if Omori sustains more damage after not succumbing, he will stay at one . After the next turn begins, however, any attack that reduces Omori's to zero will kill him normally, resulting in a Game Over.

Prior to patch 1.0.8, the game used to check heart value at the end of the turn to determine if Omori should or should not disable his plot armor. This meant that, if Omori's plot armor was triggered, and he ended the turn with more than 5% (possible by either having a healing item used on him before the end of the turn, or reducing his max through accessories to the point where he effectively always has more than 5% of his ), he would retain his plot armor hit, and would be able to survive another killing blow. It was possible to keep the immortal state indefinitely, as long as Omori never ended a turn with less than 5% .

Stat Calculation

Simply put, the buffs and debuffs affecting a stat all interact multiplicatively.

• Final Stat = base stat * (emotion effect) * (in-battle buff) * (in-battle debuff) * (release energy bonus) * (sno-cone bonus).

The calculated stat is then rounded to the nearest whole number and will not exceed 9999.

The bonus from release energy and sno-cone are only applicable to players.

Damage Calculation

In calculating damage, keep in mind that the game uses the calculated stats that has been rounded to the nearest whole number. The calculated damage formula is then multiplied by damage multipliers, if any.

• Final Damage = {[(damage formula) * (emotion multiplier) * (critical multiplier) * (damage variance)] + additional critical damage} * (flex multiplier).

Critical damage has a multiplier of 1.5 and an additional damage of +2 which is added after all multipliers have been calculated except for flex.

As mentioned earlier, the majority of attacks have a randomness factor of 20%, this means it will have its final damage deal anywhere between 80% and 120% of its calculated value (a damage variance of 0.8 to 1.2). Some attacks have no randomness factor (such as Release Energy), while some others have a different randomness factor (such as 30% for Ricochet).

• When introducing the party to a Sad Lost Sprout Mole, Hero will incorrectly claim that Sad enemies "won't do as much damage as normal." While Sad enemies generally are more likely to waste their turn, Sad does not affect Attack power whatsoever.
• From version 1.0.7 and onward, most of Hero's heart-healing skills are affected by emotion: Hero will heal characters weak to his current emotion more, and he will likewise heal characters strong against his current emotion less. The only exceptions are Tea Time, Share Food, and Fast Food, which are unaffected by emotional advantages. This is likely an oversight.
• Hero's cook skill is the only healing skill that has any variance to the % of max HP healed. This is also likely an oversight.
• Omori and Hero's sprites while Angry only have two frames of animation, as opposed to three. This also applies to Omori's 'injured' graphic as it is based off of his Angry sprite. This is likely an oversight.
• An unused emotion called "panic" exist within the files, but it does nothing other than sealing the use of skills, theoretically, it would be the second tier of afraid, with stressed out being the third.
