See title.
I know the buffbar displays two buffs, but I've learned to not trust the tooltip in the event they are (usually) wrong. So I decided to check if the melee/ranged bonuses stack more than twice and don't list it, or something even more funky happens.
__________
Melee (had 17 STR + 100 fixed damage weapon in the picture)
First hit is with no gear on, gives the correct expected damage.
100*0.55*1.0425 = 57.3375
If I insert Fured Kino, I correctly get the boost of 1x melee damage perk (when accounting for the Power boost).
100*0.55*1.0425*1.03*1.03326 =60.96282398.
If I then insert the Heels of Fury, I correctly get the boost of 2x melee damage perks (when accounting for the Power boost).
100*0.55*1.0425*1.03*1.03*1.07655=65.48584078
If I then insert the Ebonized Assault Ring, the base damage is unchanged and still remains at 65.48584078.
Lastly, when I insert the Ebonzied Ward Ring with the above, the base damage is unchanged and remains at 65.48584078.
The same holds true for the ranged versions.
Ranged (21 INT + 1000 fixed damage weapon.)
First hit is with no gear on, give the correct expected damage.
1000*0.25*1.0525=263.125
I then put on the Hag's Rags, gives the correct boost of 1x ranged damage perk (when accounting for the Power boost).
1000*0.25*1.0525*1.03*1.03629=280.8400204
I then put on the Eyestalk Wrappers, I get the correct boost of 2x ranged damage perks.
1000*0.25*1.0525*1.03*1.03*1.06855=298.285
I then put on the Ebonized Raid Ring, the base damage is unchanged at 298.285.
Lastly, I put on an additional Ebonized Raid Ring and still have a base damage of 298.285.
