OSRS Crystal Shard Calculator

How the crystal shard calculator works

Pick what you want to make, from a single crystal helm to every item a singing bowl can make, and the calculator adds up the crystal shards, seeds, coins and levels it takes. It starts on a full set of crystal armour with a corrupted Bow of Faerdhinen, the set most players work towards. Tell it what you already own and it works out what is left, what that costs at Grand Exchange prices, and how many hours each way of getting shards and seeds takes.

The level is the same in Crafting and Smithing, both can be boosted, and you get the experience in each. Below the level, Conwenna or Reese in Prifddinas sing it for you for extra shards and you get no experience. The crystal saw and crystal chime need no shards or levels: a crystal saw seed from The Eyes of Glouphrie, or a chime seed from The Path of Glouphrie, sung at any singing bowl.

Crystal armour and the Bow of Faerdhinen

The crystal helm, legs and body each raise the accuracy and damage of a Bow of Faerdhinen or crystal bow: the helm by 5% and 2.5%, the legs by 10% and 5%, the body by 15% and 7.5%, and all three by 30% and 15%. The set effect table runs every mix through the same engine as the DPS calculator, against the target, prayer and potion you pick, so you can see what each piece is worth before you sing it. A Slayer helmet on task stacks with the body and legs, and the table shows that too. To compare crystal with every other ranged setup at your budget, the gear calculator picks the best set it can find.

Corrupting the Bow of Faerdhinen

Corrupting the bow costs 2,000 shards, and the blade 1,000. The charges in it count towards that at one shard for every 100 charges, so a new bow with 10,000 charges needs 1,900 and a full one 1,800. Using the bow counts too: every 100 shots add a shard's worth of progress, so the bow corrupts itself in the end. Conwenna and Reese will do it for 1,000 more shards on the bow and 500 more on the blade. A corrupted weapon never uses charges again, and the table shows the hours of use after which the shards you would have spent on recharging have paid for it.

Where crystal shards come from

Armour seeds and enhanced weapon seeds come only from the Gauntlet. The calculator walks every run exactly, so the hours it gives are the average time until both your seeds and your shards are in, with the run counts by which half and nine in ten players get there. The CG loot simulator opens the same chest one run at a time. For shards alone, pickpocketing elves in full rogue equipment is the fastest way: each steal can give a shard and, rarely, an enhanced crystal teleport seed that Amrod trades for 150 shards. Zalcano is the only source of crystal tool seeds. The dry calculator works out how unlucky a long wait for a seed has been.

Shards also come from crystal implings, the Prifddinas guards and Iorwerth warriors, the Slayer monsters of the Iorwerth Dungeon, chopping and mining in Prifddinas, the crystal extractor on your ship, port reward bags, crystal trees and the Elven Crystal Chest. An enhanced crystal key gives back fewer shards than it takes to make, so the chest loses shards on average. Seeds you do not need can be traded to Amrod for shards, or a crystal weapon, armour or tool seed to Pennant for a crystal acorn.

Ironmen and other game modes

An ironman cannot buy seeds or materials, so the cost becomes the coins paid to the elves and the shops, and every seed and shard is earned. Pick your account type and the cost table says which parts you must get yourself. A hardcore ironman who dies in the Gauntlet loses hardcore status, and an ultimate ironman who dies there loses the items in an instanced bank.

Deadman World 345 and Hardcore Worlds

On the permanent Deadman world the Gauntlet's armour, weapon and enhanced seeds drop twice as often, three times with a charged trinket of fortuity, and singing gives ten times the experience with protected skills or five times without. Zalcano's tool seed and the elves' drops are unchanged. If another player kills you, crystal armour and the Bow of Faerdhinen drop as their seed and every shard in them is lost. Hardcore Worlds keep the main game's drop rates. Both have a Grand Exchange of their own, so their prices are marked with a ~.

Reverting and recolouring

Crystal armour, tools and the crystal bow, halberd and shield can be turned back into their seed, losing the shards in them. Turning a Bow of Faerdhinen or Blade of Saeldor back into an enhanced crystal weapon seed costs 250 shards at the bowl, or 375 with an elf. Lliann's Wares in Prifddinas sells a crystal for each elven clan at 500,000 coins, and each one recolours one piece of crystal armour or a corrupted bow or blade.
