The Treasure of Crystal Cove, aka Euphonia's Challenge, is a recurring special event that runs 1-3 times per year and lasts a few weeks. During this event, players can access a pirate island, kill pirates, collect doubloons, gems, and dragonshards and exchange them for special loot.

You can reach this public instance area via the NPC Sailor Calatin, found on the docks in the north end of the Harbor, directly in front of the entrance to Arachnophobia. Note however that Sailor Calatin is only there as long as the event is up.

Overview [ edit ]

This event is loosely called "Crystal Cove" (although, technically, that is the name of the challenge itself), and basically consists of three parts. For full details, see below, but this is the basic layout:

1) Run the wilderness part to collect two items: Treasure Map pieces, which are what need to be turned in by any/all players to open the challenge (see below), and compasses, which are what your character needs to enter the challenge part. During this part you will also collect doubloons (gold, silver and copper), which can be used to buy/upgrade basic items, which include hats that make coin-farming faster, and can be upgraded to help in the challenge (see #2, below). Doubloons can also be bartered for other rewards, including compasses (if you have too many coins and no time to farm more compasses).

During this part, most spawns will scale to your level. However, rare red-named spawns will always be highest-level.

be highest-level. You will also, occasionally, be rewarded with maps to lost treasure hoards. Optionally, click these (one at a time) and follow the arrow on your map for a level-appropriate chest.

2) Run the challenge itself. The challenge gives "Stolen Gems" as rewards. Be aware that gems come in tiers that are level-based, depending what level the challenge is run, so only high-level characters will get the highest level Stolen Gems. Gems can be traded down, but cannot be traded up, so high-level characters are needed for higher-level gems, which are needed for higher-level items (see rewards list).

3) Trade Stolen Gems for named items. This is the "reward" part. It may require you to trade in higher-tier Stolen Gems for lower-tier ones. Most items are bound-to-account, but some are bound-to-character.

Smuggler's Rest wilderness [ edit ]

This island is now populated by many types of respawning pirates, according to the level of players in the area when they spawn (for a list, see here). Dealing damage to any pirate (regardless of CR) provides a chance for an item drop upon its death. Each pirate killed has a chance to drop:

When a named treasure map is dropped, each member of the group will get an identical copy. Using the map will bestow a quest that reveals a chest on the map. Each named map is a specific quest with a specific location. If you already have a specific quest active, don't read another map of the same name until you collect the current chest. If you have several maps of the same name, you can go to that chest, collect it, read the next of copy of that one, collect again, and repeat for any other copies of that same map. Opening a named chest will draw aggro from some of the monsters in the area.

As soon as 500 treasure map pieces are collected and turned in at Euphonia's Barter Box, the Crystal Cove will be open for access for 40 minutes. A World Event message will go out to all instances of Smuggler's Rest (the message is not viewable anywhere else, including in the Rook's Gambit tavern).

The challenge [ edit ]

Usually, players complete 2 runs of the timed 20-minute Crystal Cove challenge while the door is open for 40 minutes. Alternatively, players may make many "gem-only" runs by entering the Crystal Cove, killing monsters for stolen gems, and recalling when the monsters are killed (ignoring the Kobolds and Green Dragonshards). Within the 40-minute window, you can complete 2 full Green Dragonshard completions and 19 minutes of "gem-only" runs before/between the completions.

If you have a friend that doesn't need to run the event (or an alt on another computer), you can complete 3 full runs of the Crystal Cove within the 40-minute window:

00min: Door opens, 40-minute timer starts. Party A starts a run of the Crystal Cove. 18min: Player B starts another instance of the Crystal Cove. Party A has 2 minutes left on their Crystal Cove. There are 22 minutes left on the door. 20min: Party A completes their original run of the Crystal Cove. They drop group and join Player B's party and enter his Crystal Cove instance 2 minutes late. After they enter, Player B recalls and drops group to make room for the rest of Party A. 38min: Party A completes Player B's run of the Crystal Cove. They have 2 minutes to start a 3rd run of the Crystal Cove before the door closes.

Each player will require a Treasure Compass to enter the Crystal Cove challenge. As of U17, the compass will be consumed when you open the Quest dialog box. Once you do so, you get a buff in your buff bar of 6 min where you can enter the challenge. If you haven't collected at least one Treasure Compass from killing monsters, you can buy one on the DDO Store or trade for one in Euphonia's Barter Box (note that a few Stolen Emeralds or Diamonds will trade for enough Doubloons to buy a Compass).

There are difficulties going all the way up to 30. Max allowed people per instance is a regular 6 man group. Higher level instances will reward more shards (up to +50% Green Dragonshard bonus for playing 5 levels above the highest player), while entering an instance below player level will result in a penalty to both shards and XP (even if just one level higher, unlike dungeons). If the character is 5 levels or more above the instance level, no shards, XP or gems will be rewarded at all. Even if in a group the higher level player left the instance, the penalty on this instance will be kept.

If you run with people 5 levels higher than you, you won't get any shards (unlike the xp report says), the kobold union will tell you after you finish the run. Power-leveling experience penalties apply to Crystal Cove, so any players 4 levels lower than the highest-level party member will receive -50% XP.

For example: You could run the Crystal Cove at instance level 25 with a party of 5 level 20 characters and a level 16 character and everyone would get maximum Dragonshard bonus (+50%). If the level 16 was replaced with a level 15, that character would get gems and XP but no Green Dragonshards.

Collectables [ edit ]

The following items can be collected while wandering through Smuggler's Rest or in the Crystal Cove challenge. You can then exchange them for Treasure of Crystal Cove loot.

Named Treasure Map (BtC): When used, bestows a quest that marks a point on the map with a chest that drops random loot, only for the player that used the map.

Treasure Compass (BtC): Needed to get access into the Crystal Cove

All of the gems/doubloons/map pieces Bind to Account. The Named Treasure Maps and Treasure Compasses Bind to Character.

The crafting/upgrading uses the same Barter interface used in the Mabar Endless Night Festival and Cauldron of Sora Katra crafting, by placing the requested amount of Collectables (and base item to upgrade) into the Barter interface, picking the desired recipe from the list, and choosing 'trade'.

Alternate Map & Doubloon Sources [ edit ]

Use a Pirate's Grog and go do a Harbor quest with a lot of humanoid creatures, such as Durk's Got A Secret, Kobold Assault, etc. Note that compasses will NOT drop outside of Smuggler's Rest.

The Butcher's Path is a good choice for both casters and 2h melees, with ~100 kobolds in groups of 4-8, and can be run in less than 5 minutes (just take a slow walk with Death Aura active), earning about 30-50 map pieces per run; averages out to ~350 map pieces per Grog. Doing the chest ambush is recommended; the hidden passage ambush is not

Kobold Assault works well also, after the first 100 kobolds the spawn rate seems to drop steeply. 60-75 map pieces a run. ~15 minutes per run. 350-400 per Grog.

The Tear of Dhakaan 217 kills, 17 minutes, 60-100 map pieces. too wide spread, and the village seems to have a spawn rate around 1 creature per second after you clean it.

Kobold Island Challenges: kill the Kobolds on the island which gets the parts needed for the challenge and the items for the Crystal Cove.

In the Belly of the Beast: talk to Feryl Cay'Vorym, don't drop onto the pit and keep killing respawing drow army on the stand. 800 or more map pieces per hour. (YouTube)

Difficulty doesn't matter so run them on Casual for the quests, and for the challenges just run those at the lowest level allowed.

Pirate's Grog can be bought in Euphonia's Barter Box or the DDO Store, and be freely traded so probably the Auction House too.

The fastest way to get doubloons is to kill high-level monsters in the Crystal Cove and turn in the gems for doubloons. The Pirate's Grog, which gives you a fairly high chance for doubloons for killing any humanoid monsters in the game, works in the Cove as well. If you fail the challenge (don't collect at least 100 shards), you don't lose your compass; a good team ignoring the kobolds should be able to do 5+ gem-only runs, if they clear the undead and then recall out; even solo, 3-4 runs is easily doable.

The following items are available from Euphonia's Barter Box, Euphonia's Hat Box, or Dusty Old Treasure of Crystal Cove crafting devices. You also use Conversions of Crystal Cove to convert legacy versions to new stats.
