Schism Shard Crafting

You can craft Schism Shards acquired from the raid Killing Time with certain epic-level weapons to receive an upgraded or altered legendary weapon. Schism Shards are, and the crafted weapons are.

Crafting NPC

Base Weapons
Unlike most crafting systems, the base weapons capable of being upgraded exist across three entirely different quests from separate adventure packs:


 * White Plume Mountain
 * Legendary Echo of Blackrazor - Great Sword
 * Legendary Echo of Wave - Quarterstaff
 * Legendary Echo of Whelm - War Hammer


 * Desire in the Dark
 * Legendary Wave of Despair - Bastard Sword
 * Legendary Wave of Sorrow - Great Sword


 * The Temple of Elemental Evil
 * Epic Leopard's Chill - Scimitar

Sentient Jewels
Each of the recipes to upgrade or alter the White Plume Mountain weapons also requires that weapon's respective sentient jewel.


 * Sentient Jewel of Blackrazor
 * Sentient Jewel of Wave
 * Sentient Jewel of Whelm

Upgrading Weapons

 * Base weapons must not have sentient jewels slotted into them. In order to use such a base weapon, the jewel must first be removed or destroyed.
 * Additionally, sentient jewels used as ingredients for upgrading must have 0 Sentience XP.
 * Note that with the White Plume Mountain weapons, each has an option of either a direct upgrade to the weapon, or an upgrade to a secondary weapon type. Be careful when making your selection!

WARNING: Any Mythic or Reaper bonuses the base weapon has will be lost on upgrade.
 * As of Update 41, players will be able to spend a new raid ingredient,, to add Mythic +2 or Mythic +4 bonuses to the upgraded versions of these weapons. (Source: )
