There is an Amazon multi-shot stat damage effect error.
Multi-shot weapon damage is not applied, so normal hits and damage are displayed similarly.
It’s not only a visual error, adding up the synergy bonus from guided arrow from -75% weapon damage on the tooltip.
It also does not add the synergy bonus from guided arrow to the damage itself; a fully sinergyzed multishot arrow simply loses +240%ED.
I hope they will correct both bugs (the second is more impactful) in the next patch.
AFAIK the synergy works but because the 75% damage penalty is applied at the end, it’s not boosting by a lot. A fully synergized Multishot will do a little less than a normal attack instead of ~25% less.
The only bug I see is the fact that it’s showing a modified Weapon Damage which add the synergy bonus directly on top of the 75% weapon damage, there’s no way the synergy completely remove the damage penalty and goes way beyond that up to 315%, there’s no way, it’s a display bug.
