We have a great many "shard" type items in the game, which are components or crafting mats for other objects, and we have a "shard collector's chest" from Wonderland. Very, very few items of this type actually go in that chest, which is a huge waste of potential space. Here is a list of just some of the items I have found which seem like they should be able to go into the Shard Collector's Chest:
Accessory, weapon, armor anchoring shards of any grade. We have so many of these cluttering up our chests.
Machine Anchoring Shards
Red Dragon Spinal Ridge Shards.
Chrome Sub Design Scraps
Ayanad Scroll Scraps
Vaultstone Shards
Jade Orb Shards
Wrathsmite Armor Shards
Superior Wrathsmite Axe Shards
Abyssal Shards (for Abyssal Crystals)
Abyssal Library and Heart of Ayanad Shards
Warden's Manashards
Wrapped, unwrapped, bound and unbound Serendipity Stone Shards (why are there so many variants of this item?)
Synthium Stone Shards of any grade (I still think these should go in the Equipment Enhancement Chest, but at least give us somewhere to put them)
Specialization Snowflake Shards
Nutcracker Costume Pieces and Statue Shards
Titan Event Shards (Ancient Staff, Ice Armor, Ice-Shards)
Cursed Armor Scraps
Acid Goblets
Possible additions that are maybe stretching it a little:
Fine Glow Lunarite
Shining Fragments
Tower Gate Key Shard
Maybe even Manastorm Crystals? Although that's maybe really pushing it lol.
Let's put this wasted storage space to good use.
