Stat:
Str 266

Bow Ul'dahn Longbow
Arrow Dated red coral arrow

Light shot damage range non-critical on Corroded Coblyn 670 ~ 790 (absolutely no hit above 800)

Stat:
Str 230
Dex 266
Attack power 480
Bow Ul'dahn Longbow
Arrow dated red coral arrow

Light shot damage range non-critical on Corroded Coblyn 710~805 (absolutely no hit below 700) [WS damage range also improves compared to 266 Str]

I tested many many times, would someone else please try and confirm this?
The test on level 1 enemy may has many flaws. However I do not understand why losing Str and Attack power would result in a decrease in attack range on level 1 enemy.

Thank you very much to whoever can explain this m(_ _)m
