When equipped with the Rune Ring, these universal weapon rune attacks will just randomly sometimes not apply the +20% damage from the Rune Ring. Tested by repeatedly using these rune attacks against both enemies in the world and the dummy in Sacrament; with nothing else equipped and no other modifiers present, my Throw Axe will randomly swap between doing 140 damage and 168 damage, sometimes back and forth, sometimes one or the other for 20 hits in a row before swapping back to the other.
Hm, there are some problems with them, like this: Throw Axe does 0 damage after Breach Refined update - #7 by stokesbook
I’ll escalate this YourSponsor!
