I’ve been playing a fair amount of Void Knight lately, and I’ve noticed some disappointing interactions between temporary buffs and echoed skills. Some of the most blatant are interactions between Void Cleave, Abyssal Echoes, and Erasing Strike.
Void Cleave’s “Obliterator” guaranteed critical strike does not apply to echoes of Erasing Strike, and Abyssal Echoes “Void Supremecy” damage bonus to Void Cleave and Erasing Strike do not apply to echoes. I think that this interaction is both intuitive and very disappointing. This devalues echoes as a whole, and makes building for echoes (the main gimmick of the mastery) much less appealing in these instances.
