Isle of Bios

An old man in the cave keeps rambling about Morocc coming back. Two travellers from Prontera, the chatty Vrid and the quiet Zeith, touched a strange seed and found themselves on an island in the sky, the Isle of Bios, a place conjured in the mind of a Grim Reaper who plans to feed them to Morocc.

Going in sets the quest Memorial Dungeon: Isle of Bios, which ends at the next 04:00 server time, and a short one that lasts 5 minutes. For those 5 minutes you can walk back in if you did not finish. After that, until 04:00, the seed says the dungeon "cannot be accessed for 23 hours after your last visit". The 23 hours in that line is not what the game uses: the wait ends at 04:00.

You arrive at (17, 93). At (67, 97) the party meets Vrid and Zeith, and the Grim Reaper (Ankou in the dialogue) appears briefly, sneers that they walked into his trap and vanishes. The two chase him and are gone. After about a minute a system line says to kill every enemy on the island and use the exit "at 3 o'clock".

The island holds 74 monsters, one at each of 74 set spots: 28

Corrupt Orc Baby, 23

Corrupt Baby Desert Wol and 23

Corrupt Familiar. The map counts down at 10, 5 and 1 monsters left. When the last one falls the exit at (291, 102) opens and sends you to island 2 at (17, 93).

Same as island 1, with stronger versions. Step in and the system line asks again for all enemies to be killed: 28

Corrupt Orc Warrior, 23

Corrupt Desert Wolf and 23

Corrupt Phen, 74 in all. Again the exit is at (291, 102), now leading to the last island at (45, 68).

Walk up to Vrid and Zeith at (64, 74). They say the monsters seem to grow with time, like children. The Reaper shows up again and calls his undead soldiers, then freezes everyone within 30 cells of the middle (69, 67) for about 17 seconds ("On the Isle of Bios, each day is a lifetime...") before the fight starts.

After about 80 seconds three waves of 27 monsters each, in a grid at x 62 to 78, y 80 to 92, come one after another. A new wave starts a moment after the last one is dead:

All have 12,390 base and 16,104 job EXP. All 229 monsters before the boss are worth about 2.84 million base and 3.69 million job EXP.

Then the Reaper steps out again and the boss fight begins at (70, 67). Grim Reaper Ankou (Reaper Yanku on the monster page): level 159, Undead, Undead, 50,000,000 HP, MVP, 300,000 base and 330,000 job EXP. Skills: Comet and Dragon Fear around himself, Cross of Darkness on his target. He mutters "Feel the fear of death!" and "Lord Morocc will return soon."

When he dies he says his goal has been reached and Morocc will come back, and Vrid and Zeith get free of the hold. About 23 seconds later talk to Vrid: he gives a Heroic Token and warps you out to the Flame Cave at (45, 63). The Token is given on every completion.

Every ordinary monster of the isle drops the same list:

The Grim Reaper:

As the MVP he also gives two separate 20 % rolls: Yggdrasil Berry and Yggdrasil Seed.
