Infinity Arena

Infinity Arena

The Infinity Arena is an end-game challenge located in the Keepers' Tower. It is gated until the player reaches Keeper Seeker. The player faces increasingly difficult teams, ending after one loss.

Combat Mechanics[]

Team and Battle Structure[]

Infinity Arena pits the player against teams of random Monsters. These are 3v3 battles similar to a wild encounter. These Monsters can be any species, except for the Spectral Familiars.

At the start of each battle, the player is given the opportunity to choose 3 Monsters from their current team of 6. The player's Keeper Rank determines the level of the first opposing team. After each win, the level is increased depending on the number of stars achieved on the previous battle. Rewards are generated in the background. A new team of 3 random Monsters is generated at this level. The player is then given the opportunity to select 3 new friendly Monsters from their current party.

Stars	1	2	3	4	5	6
Level Increase	2	3	4	5	7	10

The current level of the run will also affect the stats and difficulty of the Monsters you're against:

Level 40 onwards, opposing Monster's Health scales less.
Level 70 onwards, one of the opposing Monsters will be shifted.
Level 100 onwards, opposing Monsters will start to use their Ultimate skills.
Level 130 onwards, two of the opposing Monsters will be shifted.
Level 160 onwards, all of the opposing Monsters will be shifted.
On lower levels, opposing Monsters are less resistant to Poison, but become more resistant to it as well as Burn and Congeal with higher levels.
- The scaling used is calculated as follows:
  ${Scale\ percent = min \left (\frac{Arena\ level}{200}, 1.0 \right )}$
- Poison damage is modified and decreases on higher levels, capped at 0.3.
  ${Poison\ damage\ multiplier = 1.0 + (1.0 - (1.0 - Scale\ Percent) * (1.0 - Scale\ Percent)) * (0.3 - 1.0)}$
- Burn damage is modified to 1.1 but decreases on higher levels, capped at 0.35.
  ${Burn\ damage\ multiplier = 1.1 + Scale\ percent * (0.35 - 1.1)}$
- Congeal damage is modified to 1.1 but decreases on higher levels, capped at 0.85.
  ${Congeal\ damage\ multiplier = 1.1 + Scale\ percent * (0.85 - 1.1)}$

Consumables[]

Consumables can be used and are refunded at the end of the run.

Revive Limit[]

The player is limited to using up to 5 revive actions per round. This includes using items (Phoenix Tear and Phoenix Serum), as well as using active skills (Revive and Gift of Life). Note that auto-revive passive skills (Phoenix Affinity and Charged Rebirth) do not count toward this revive limit.

Infinity[]

At the start of their turn, all Monsters (allies and opponents) receive one stack of Infinity, which increases damage dealt by 25%. If a Monster is revived after being knocked out, it will regain the current Infinity stack count.

Rewards[]

Rewards are given to the player after completing or dropping out of an arena run. Some rewards are unlocked once you reached a certain Keeper Rank. You can get up to 4 rare items and 4 common items per run (maximum of 8 unique rewards). Which item you get is totally random, and not based on the level your run ends. Any consumables that were used during the run are also refunded.

Arena Coupons and Reward Boxes are rare items that can be obtained from Infinity Arena. An Arena Coupon is rewarded every 12 levels, which can be used to buy items from the nearby merchant. A random Reward Box is rewarded every 6 levels, and after reaching 60 levels above the start level, it is rewarded every 4 levels. All other items are common items and can be obtained in high quantities.

Keeper Rank[]

The player's Keeper Rank determines the level of the first team the player fights against as well as unlocks rewards and higher level Reward Boxes.

Arena Coupon Trader[]

Unlike other merchants, the Arena Coupon Trader sells items in exchange for Arena Coupons. More items become available as the player increases their Keeper Rank. He sells all unique weapons and accessories, as well as Shift, Switch and Clear Stones. He also sells all 39 Relics if Relics of Chaos is active after the player reaches Keeper Master.
