Normal

In September 2019, the Prey-Isys Normal dungeon was added as part of the Season 5: Act.05 patch. Just like Luke and Anton Normal, players can go through 5 different dungeons learning the mechanics of each boss they encounter with the 6th one being the final boss. Due to the amount of bosses that were introduced, the dungeons will randomly change every day at 9:00 UTC.

Raid

Upon completion of Tightening Clutches of Sin, players gain access to Prey-Isys Raid, considered the toughest content in the game as of the end of 2019. It is meant to be cleared with 3 parties of 4, or 12 players in total. The Raid is split up into two areas which serve as phases—the Outskirts and the Depths.

A single player can create a Raid Group by speaking to Niu while in the Raid Channel. The Raid leader is able to organize their raid's parties and are responsible for coordinating their parties' objectives. The Raid can then be initiated by speaking to Arthur when all Raid members fulfill the entrance requirements.

Entrance Requirement

Completion of Tightening Clutches of Sin (one-time)
1 Lupsong's Relic, which is contained in Lupsong's Relic Box purchased from Niu for 50,000 Gold and 3 Refined Terraniums.
Must be Thursday, Saturday, or Sunday (9:00 UTC)
5,383 Exorcism or higher.

Party Composition

Prey-Isys Raid typically utilizes 3 parties of 4 members each -- the red party, yellow party, and green party. There is no specific in-game designation for who belongs in which party, but player convention is to make the red party the strongest, followed by yellow party and then green party. Due to the difficulty of Prey-Isys Raid, it is recommended that every party contains:

1 Saint, Seraph, or Hekate
At least 1 pure DPS
At least 1 synergy DPS

The 3 parties typically have different expected responsibilities, but no party is locked out of any particular dungeon so this is up to the raid leader's discretion.

Battlefield

For the entire raid, instead of having a "town" area like Zelva or Noblesky as a "home base", the raid's base area is on Slenikon's back, much like the in-dungeon environment of Tayberrs - Fallen Paradise. Slenikon's back is split into 3 sections -- the middle section is a "safe" area, where nothing happens, whereas the two side areas (head and tail) are for descending into dungeons. Slenikon flies around the Outskirts (Phase 1) and the Depths (Phase 2) passing by each dungeon every cycle. During Phase 1, players move to Slenikon's head (right side) to enter the next-encountered Interception (Slenikon Defense) dungeon, or move to Slenikon's back to enter the next-encountered non-Interception dungeon (Magic Tower, Garden, or Sanctum). In Phase 2, players move to Slenikon's head to enter the Sky Nest, or move to his tail to enter any other dungeon (Battleground, Observatory, or Grand Garden). Players should be careful to move to Slenikon's head/tail only when the next dungeon Slenikon is passing is the one they wish to enter.

The raid leader is able to use a tool on the map to designate certain dungeons as the next target for each party (red, yellow, green). Players should pay attention to these map markers, particularly if they are not using a third-party voice chat program as it can be difficult for the raid leader to type to communicate while trying to clear dungeons.

Phase 1: Outskirts

At the beginning of Phase 1, various dungeons spawn in a circle around the Outskirts. Each dungeon run has a limit of two Life Tokens throughout the party, and if failed cannot be attempted again until Slenikon flies past the dungeon again. Two parties cannot be in the same exact dungeon at the same time, though it does not matter if they are in different dungeons of the same type. On the top, bottom, left, and right of the map -- maps 1, 5, 9, and 13 -- are the four Sanctums, which must be cleared to clear Phase 1. There will also be, in random locations, two Interceptions which cannot be flown past without clearing them or else Slenikon will take damage; two spots on a countdown spawning new Interception dungeons; two Magic Towers (Aries Kelly and Villainous Greta), and two Gardens (Omega Guardian and Cumulonimbus).

The goal of Phase 1 is to clear the 4 Sanctums. With each cleared Sanctum in Phase 1, Explorer Ruhos will appear on the middle part of Slenikon's back for about 25 seconds, allowing players to repair and buy in-raid recovery items from him. However, Slenikon starts at 10000 HP, and during Phase 1, Slenikon's HP decreases at a constant rate of 2 HP/second. In addition, when passing Intercept stages, if players do not enter the dungeon or defeat the intercepts, Slenikon suffers an additional 1300 damage to his HP. If his HP reaches 0, the raid will fail. The Magic Towers, if they are not entered, will spawn intercept dungeons whenever Slenikon passes them. Clearing one disables the Tower for 360 seconds/6 minutes, during which time any Intercepts that are spawning from that Tower will also be disabled.

The Gardens are one-time clearable dungeons that individually provides a damage boost of 25% across the entire raid, for a total of 50%. Clearing both will also boost damage done in Sanctums by another 30%, for a total of 80%. (UNDER CONSTRUCTION)
