I'm a bit confused here on how all the stats work in favor of Arch damage. Not know the mod limits of arch and only that dex and pie increase it's damage I went ahead and maxed my dex as much as it will let me and put the rest on pie. With all Dex gear on I have 178 dex at lvl 35. I was starting to wonder about the cap so I asked a lvl50 arch if he knew what it was and he said he did not but before 1.20 it was 174. Well that made me think that maybe I've overdone it on dex and before I add any more I better test out to see if it has any effect. So....I set out and did a little experiment and these are my results.

(Only swapped out DEX gear, leaving everything else the same)

DEX 175, Mob lvl30

High: 146
Low: 129

DEX 155, Mob lvl30

High: 145
Low: 124

That's with 30 Mobs each.

Next test.

DEX 175, Mob lvl35

High: 118
Low: 102

DEX 155, Mob lvl35

High: 118
Low: 101

Again doing 30 each.

Finally just too see if maybe it effects weaponskill damage only I did 10 Heavy shots with 175 and 155 Dex and got...

DEX: 178

High: 262
Low: 226

DEX 158

High: 257
Low: 226

I do understand that this is not a thorough experiment but the numbers looked so close I didn't even bother increasing the sample size. So I'm left wondering what the cap on dex is % wise and what would increase my damage more substantially, Pie or Attack Power?
