Lost Ark

Unlike the steam description suggests you need to upgrade the first five ships to level 10, being Estoque, White Wind, Sturmbrecher, Eurus and Brahms.

You will need a ton of coin selection chests and pirate coins, so I suggest exhausting every source possible, being one-time island quests, Una reputations that reward pirate coins, special events as well as the daily adventure islands.
Additionally stronghold merchants sometimes sell the necessary parts for another currency, which I strongly recommend buying.

The total cost for upgrade materials per ship is:

322500 Pirate coins or 162x Coin selection chests if you convert sun coins.

1500 Gienah's coins
2800 Sceptrum's coins
4250 Arcturus Coins
3200 Ancient Coins

=11750 total coins or 120x Coin selection chests.

1383 normal ship parts
117 uncommon ship parts
94 rare ship parts

You need to kill the golden peach 10 times. Per admission two of them spawn, meaning you have to visit the island a minimum of five times.

5 weeks of clearing P1-P3 Argos with no battle items unlock this achievement. You do not need to survive the encounter and are allowed to revive which makes this easier than it sounds, especially if you outgear the content.

Unlike the description says, this requires you to upgrade the manor to level 5, which you can do so at stronghold level 35

To unlock this achievement you need to 100% a single continent in the adventure tome. West Luterra and Yudia have the lowest rapport requirements so it is advised to complete one of those.

This description is misleading as riding a raft is only one of three criteria to unlock this achievement. You need to:

• Ride a raft in Changun (Anikka)
• Ride a monorail in Stern (Arthetine)
• Ride the magick gondola in Vern Castle (Vern)

This does not refer to guild vs guild matches but "Co-Op battles"
Co-op battles are timegated and you can apply on the 3rd page of the PvP matchmaking interface. You can queue solo without any guildmates to unlock this.

This refers to the hoverboard section in the storydungeon "Heart of Sceptrum" and not the mount. Simply revisit the dungeon and die to unlock the achievement.

To unlock you actually need to clear 20 guardians without anyone dying. You could solo them if you run into trouble getting this with random players.

A tad bit misleading: Yozmund is not added in our version but also not necessary to unlock the AV and "Phantom island" refers to "Fantasm Island"
