Since we recently have gotten The Harbringer, why not a dagger as well?
An idea for the dagger:
You need blood essence from valkor for it.

Name: Soul Slasher
Damage: honestly don't know what's good but not OP for an epic dagger
Attack Type: Pierce
+Dexterity
+Strenght
+One Hand Pierce (leaving numbers out same reason as damage)
Range: Melee
Delay: 20
Skill: One Hand Pierce
5% Chance
Attacks Only(or maybe spells as well? since it is useable like any other dagger by magic classes): Ethereal Damage, Maximum Damage
Usable By: ELAR, CRSB, BLDM, RNGR, CONJ, SORC, WIZ, SHMN, SPRT, SCT, MAGE, WAR
(maybe add berserker as well? ;D this is wishfull thinking from me though haha)
Attuning
Equip Slot: Right Palm
Requirements: -Current Adventure level minimum 95
-One Hand Pierce Greater Than 950
Bulk: 8

What are your thoughts? I think something like this would fit with daggers though, maybe tweak the effect a bit but.
