Did some quick and stupid testing of this; was always known that defense got a damage bonus in raids and actually this was pretty easy to nail down on beta with everyone’s having Natalya up haha.
Test: comparison of attacking Natalya vs defending Natalya damage
Control: same attack stat on troops for both teams (as they affect her damage)
TLDR: appears to be a 20% damage increase, which is a nice round number as expected.
Pics or it didn’t happen time!
My setup:
Opponent setup:
Defender Natalya damage against two different heroes:
Attacker Natayla damage against two different heroes (sorry the Perseus shot isn’t great, the damage does match identically to the other hit)
238/198 = 20% when rounded, QED.
