Symphony of Mercy feedback

[Tinderox]

I notice that Symphony of Mercy do not correctly snapshots power strength in the moment of the ability cast. Making the idea of a rotating, self sustaining buff inconsistent.

For example- a 100% strength jade use grimoire alt fire to proc vome invocation, increasing power strength by 60%. Now whit a 160% power strength jade cast Symphony of Mercy. The buff correctly depicts a 160% increase weapon damage from Deathbringer. when cycling through the buff all seem normal until vome invocations power strength buff expires. The next time you rotate to any other Symphony of Mercy buff, the power strength of the ability restart.

I noticed this feels bad not working which makes it kinda useless
