The Simulation Room is a location and gameplay mechanic in Goddess of Victory: Nikke.

Lore[]

A virtual environment simulator sequestered in the Ark. It's common for Nikke squads and commanders to be sent here before a mission to make sure their skills are up to the task. Newly-created Nikke may also be put here to learn the ropes of combat before undergoing a live-fire exercise.

The AI Einkk is the primary overseer of simulations, but the Elysion CEO Ingrid will also work here from time to time.

Gameplay[]

This is the primary method of acquiring the materials needed to upgrade a Nikke's Skills and Burst, aside from microtransactions.

The Simulation Room sports 5 different levels, with more levels being unlocked as the player progresses in the campaign. Each level is split into 3 sectors (A, B, C), each one with increasing recommended power levels, but also increasing rewards to match. Successfully clearing a block will retroactively clear all blocks in levels below the one just cleared, giving out the rewards of those lower levels and streamlining material farming. Simulation Room rewards and progress reset every day.

The Simulation Room itself plays as a sort of roguelite progression. Each "step" in a block will contains various encounters and decisions that must be made, eventually culminating in a final boss at the end of the block. Nikke HP status is carried over between battles, meaning if a Nikke is defeated, they cannot be revived unless an event is triggered that can revive Nikkes or the player exits the simulation.

Encounter Types[]

Battles[]

Buff Triangle R Buff Triangle SR Buff Triangle SSR Buff Triangle Epic
Buff Circle R Buff Circle SR Buff Circle SSR Buff Circle Epic
Buff Square R Buff Square SR Buff Square SSR Buff Square Epic
Buff Rhombus R Buff Rhombus SR Buff Rhombus SSR Buff Rhombus Epic

Fight against a group of Raptures to earn a special buff that carries through the rest of the run. The battle window will denote what kind of buff is earned on victory, either by Category (Attack, Survival, Technical) or by Chain Type (Triangle, Circle, Square, Diamond).

Basic Battle[]

Denoted by a grey border, these are battles with a power level at or below that of the block's recommendation. These can be automatically skipped if the team's power level is significantly higher than the recommended level.

Hard Battle[]

Denoted by a red border, these battles feature stronger enemies and are NOT skippable, regardless of any power disparity in the player's favor. There is no empirical correlation that undertaking harder levels means better buffs, so they're mostly there to make the run last longer, particularly upon reaching Sector C of a stage where a majority of the battles are hard battles.

Boss battles are also considered hard battles, and thus unskippable. The difference is that boss battles guarantee the choice of one of three Epic-level buffs (except the Sector C boss, as clearing that boss will also clear the entire stage)

Random[]

The player does not know what the event will be or its rewards/consequences until they go in.

ICU / Recovery Room[]

The player is given a choice between healing a percentage of all active Nikkes' HP or reviving a certain number of KO'ed Nikkes with a certain percentage of HP. The exact scope of the healing varies from instance to instance.

Buff Enhancement[]

The player's buffs can be altered, either in Shape (affects Buff Chain) or Rarity (affects buff scaling). This can either apply to one or all of the buffs the payer has. Note that the player can never gain or lose buffs from this event, meaning this event is pointless if no buffs are active.

Buffs[]

Buffs are special status boosts applied to eligible units during a run of Simulation Room. Some buffs are always active, some run on a percentage trigger chance, and some rely on fulfilling certain conditions. Buffs can either be universal, or can affect specific Nikkes based on a category (Class, Weapon, Manufacturer). While any buff can come in any icon type, some can be split based on their category

Buff Chain[]

The "Buff Chain" mechanic increases the overall scaling of buffs based on matching sets of buff icons. Buff Chain goes up to level 5. Buff Chain can and will fall if buffs are altered or erased.

Level Requirements
1 Baseline level. The default if no other Buff Chain conditions are fulfilled
2 At least three buffs in the chain share an icon
3 Two matching sets of three
4 At least six buffs in the chain share an icon
5 All buffs in the chain share an icon

Buff Legacy[]

Players who clear at least one Sector of a stage can choose to save one buff from their lineup should they abort the run. All non-Epic buffs are eligible to be saved. Buff Legacy will also trigger when Sector C is cleared.

While Buff Legacy originally reset daily, as of the Lion Heart update, it will only reset once every two weeks, at 5:00 every other Tuesday (UTC+9)

Overclock Mode[]

A limited-time high-difficulty version of Simulation Room, unlocked after clearing Sector 5-C. While gameplay is largely the same as standard Sim Room 5-C, and Buff Legacy is carried over, players have a choice of difficulty modifiers that can strengthen foes, weaken allies, or impose other restrictions to add challenge. Every modifier increases Core Ratio by a certain amount. Clearing an Overclock Run will award additional skill materials based on Core Ratio level. Overclock rewards will refresh every two weeks after Buff Legacy is reset. Overclock-specific rewards are NOT subject to Full Burst Day bonuses.

Clearing an Overclock Run will also retroactively clear Sector 5-C Normal and all other stages below it.

Modifiers[]

Each modifier is codified from Level 1 to Level 5, with higher level modifiers imposing greater challenges. While multiple modifiers can be selected from the same Core Level (column), they cannot be selected from the same category (row) or if the effects are mutually-exclusive. Modifiers will regularly be altered or swapped out between seasons of Overclock.

Example: Taking Rush Hour I, which cuts the time limit by 10%, locks out the option of taking Rush Hour II or III. If a player takes the Vacation Order I modifier, they cannot take Stopwatch Burst I.
