Morphling

Just as Morphling exists on two planes at once--both terrene and astral--the blade of tears is a weapon of extreme versatility, both ethereal and not. Only the tears of the slain are real.

This item comes with custom particle effects and a custom ability icon for Adaptive Strike. It was based on the in-game item Ethereal Blade. 
Originally can be found in chest #71 - Lockless Luckvase and #75 - Imbued Lockless Luckvessel.
Editions of this item unboxed from 75 - Imbued Lockless Luckvessel come in Genuine quality.
