Adventure ​

Adventure content is available to players as a first step in developing their avatars. For a detailed description of Adventure content, see the official documentation.

World ​

The adventures of the Nine Chronicles begin in Yggdrasil, and there are new worlds after that, in the following order: Alfheim, Svartalfheim, Asgard, and so on. This data comes from the WorldSheet.

You can use the 9c-board service[1] to view the WorldSheet.

Yggdrasil, where you begin your adventure, is open when you create your avatar. Subsequent worlds are unlocked by meeting certain conditions. More information can be found in the WorldUnlockSheet.

Like WorldSheet, you can check it out in 9c-board.

Stage Challenges and Rewards ​

Each world contains multiple stages, each with different rewards for completing them. Stage information can be found in the StageSheet.

Stage Challenge Cost ​

When you look at the StageSheet, there is a field called CostAP. This field represents the number of action points required to progress through the stage. Players can spend their avatar’s action points to progress through the adventure.

Stage Waves ​

A stage consists of several waves, each of which must be cleared before moving on to the next wave. Wave information can be found in the StageWaveSheet.

Nine Chronicles currently has all stages set to three waves. The number of waves your avatar completes determines the number of stars you earn in the stage. The number of stars also determines the rewards, as shown below.

  • 1 star: EXP
  • 2 stars: EXP, items
  • 3 stars: EXP, items, unlock next stage

Stage Buff ​

Stage buffs are buffs that the player can receive when progressing through a particular stage. These buffs can be found in the CrystalRandomBuffSheet and CrystalStageBuffGachaSheet.

Item Slots ​

There are item slots available to you as you progress through your adventure. You can equip different items in these slots to give you an advantage in combat.
Items that can be used in an adventure include equipment, costumes, and food.

Rune Slots ​

As you progress through your adventure, you can equip runes to gain various effects.

Repeat Battle ​

Adventures can be repeated, and AP potions can be used to do so.

Battle(StageSimulator) ​

Battle is turn-based, and players can use various items with their avatars to defeat enemies. Adventures utilize the StageSimulator class to run battle. This class manages the flow of battle and handles the events that occur on each turn.

When a battle begins, it creates a player avatar.

Wave ​

When a battle starts, the first wave begins. If you don’t clear the wave, the battle ends, if you do, you move on to the next wave, and if you clear the last wave, the battle ends.

Turn ​

When a wave starts, a formula is used to give the highest priority character a turn, which is determined by the character’s SPD(Speed) stat.

  1. Wave starts.
  2. The player avatar has a priority of 100[2] / avatar’s SPD stat.
  3. All enemies in the wave have a priority of 100 / enemy’s SPD stat.
  4. Give the turn to the character with the highest priority, i.e., the smallest 100 / SPD stat.
  5. The character granted a turn in (4) takes the turn.
  6. Increase the priority of characters that were not granted a turn in (4).
    • Multiply by 0.9 if the character is a player and used a non-Basic Attack skill in the previous turn.
    • Otherwise, multiply by 0.6.
  7. Characters granted a turn in (4) again have a priority of 100 / character SPD stat.
  8. Repeat steps (2) through (7) until the player avatar dies or the wave is cleared.
  9. Wave ends. Repeat from (1) for the next wave if one exists.

Skill Activation ​

All characters, including avatars and enemies, can activate skills. Skills include a variety of offensive and buff skills, including Normal Attack. Which skill is activated is determined by the activation chance of each skill.

Skill Types

Normal Attack Hits ​

Normal Attack is also treated as skills in Nine Chronicles, and whether or not they hit is largely determined by the attacker’s and defender’s levels and HIT stats, with a few other formulas.

Nekoyume.Battle.HitHelper.IsHit

  1. Get a value A between -5 ~ 50 with (attacker's level - defender's level).
  2. Use (Attacker's HIT stat * 10000 - Defender's HIT stat * 10000 / 3) / Defender's HIT stat / 100 to get a value B between 0 ~ 50.
    • If the attacker’s and defender’s HIT stats are less than or equal to 0, then it is scaled by 1.
  3. Use A + B to get a value C between 10 ~ 90.
  4. Find a random number D between 0 ~ 99.
  5. finally, if C is greater than or equal to D, treat it as a hit.

Combo ​

Avatar’s attacks can have combo effects.

  • The maximum number of combos depends on the avatar’s level. For example, at level 1, you can get up to 2 combos, and at level 250, you can get up to 5 combos.
  • If you fulfill the combo increase condition after getting the maximum combo, you will start with 1 combo.

Increase Combo

  • Successfully executes a normal attack.
  • Successfully executes a skill with the SkillSheet.Combo field set to true.

Reset Combo

  • Normal attack fails.
