Necron's Blade Scrolls

Necron's Blade Scrolls are a series of scrolls that can be applied onto a Necron's Blade and its upgrades Hyperion, Scylla, Astraea, and Valkyrie to give them abilities.

Obtaining
Necron's Blade Scrolls are rare rewards from Dungeon Reward Chest in The Catacombs - Floor VII. They cost to open.

Usage
Necron's Blade Scrolls can be applied to Necron's Blade and its upgrades Hyperion, Scylla, Astraea, and Valkyrie in an anvil to give them their respective abilities. They do not cost XP levels to apply.

There are 3 scrolls: Implosion, Wither Shield, and Shadow Warp. Applying two of the three scrolls to the same weapon grants both abilities to the weapon. Applying all three of these scrolls to the same weapon combines the abilities into Wither Impact.

Implosion
This scroll can be applied to a Necron's Blade granting the ability Deals damage to nearby enemies. Cooldown:

When the ability is used, an implosion is created 6 blocks in radius and centered on the user. All enemies in range take 10,000 base ability damage. The ability costs 300 Mana and has a cooldown of 10s.

Wither Shield
This scroll can be applied to a Necron's Blade granting the ability Reduces damage taken by for  seconds. Also grants an absorption shield that gives of your Critical Damage as health, after  seconds  of the shield is converted into healing. Cooldown:

When the ability is used, it reduces the damage taken by 10% for 5s. In addition, it grants 1.5x its user's as a 5-second absorption shield. When the 5s is up, 50% of the remaining shield is converted into healing and applied to the user. The ability costs 150 Mana and has a cooldown of 10s.

Shadow Warp
This scroll can be applied to a Necron's Blade granting the ability Creates a spacial[sic] distortion blocks ahead of you that sucks all enemies around it. Using this ability again within  seconds to detonate the warp and deal damage to enemies near it. Cooldown:

When the ability is used, a spatial distortion of white particles is created 10 blocks in front of the user. All enemies within 3 blocks of the distortion are sucked in. If the ability is used again within 5s, the distortion detonates, dealing damage to all enemies within it. The ability costs 300 Mana and has a cooldown of 10s.

Wither Impact
Teleports ahead of you. Then implode dealing damage to nearby enemies. Also applies the wither shield scroll ability reducing damage taken and granting an shield for  seconds. Cooldown: 0.15s

When the ability is used, it arrests its user's momentum and teleports them 10 blocks in the direction they are looking. This teleport cannot pass through walls, including iron bars, but can pass through 1-block holes in iron bar walls. At the teleport destination, a 6-block radius implosion is created, dealing 10,000 base ability damage to all enemies within range. In addition, the Wither Shield effect is applied. The of the Wither Shield and Wither Impact abilities don't stack; the next Wither Shield will only apply once the existing Wither Shield expires. The ability costs 300 Mana and can only be activated every 0.15s.

Trivia

 * During the Necron Boss Fight (or other situations where mobility tricks don't work), Wither Impact can still be used. All aspects of the ability will work except its teleporting.
 * The teleport aspect of the acts much like the  ability of the Aspect of the End.
 * An Ultimate Wither Scroll, which applies Wither Impact to a Necron's Blade directly, exists as an unobtainable, admin-only item. Several of them have been given to 56ms.
