When the 4 buffs are removed and the dragon enters the vulnerable state it is supposed to take increased damage, but damage numbers appear the same. This was mentioned by several content creators and still appears to be the case.
#Copper dragon / Resurgent dragon damage bugged?

Dear Traveler.
Can you please provide us with the video of this issue? So that we can check for you.
Thank you for your patience and understanding.

The season ended for me. But please play test this. That was my thought every fight - making the dragon vulnerable does nothing.
