So let’s try that with DEX. I’m assuming you are using 400 STR with just the basic per point value of 2 atk. So let’s use 400 DEX with per point value of 5c.atk.
DEX
(2000atk x 1.5) + (400 x 5c.atk)
3000 + 2000
5000 c.atk
STR
(2000atk + (400 x 2atk)) x 1.5
2800 x 1.5
4200
So placing them side by side
400STR: …~0.515white
400DEX: …~0.437white
dps = non-crit% x white + crit% x yellow
So what crit rate will make these equal
Now let’s try double gear atk 4000
DEX
A normal would be
4000
~0.605
(4000atk x 1.5) + (400 x 5c.atk)
6000 + 2000
8000 c.atk
STR
4000atk + (400 x 2atk)
4800
~0.654
(4000atk + (400 x 2atk)) x 1.5
4800 x 1.5
7200 c.atk
400STR: …~0.654white
400DEX: …~0.605white
Interesting.
