Max DMG trials will end with an un-augmented
Gandiva or
Harrier (DMG:89 or DMG:84).
Occ.Atk.X trials will end with some aug'd variant of the
Condor. I'm not sure if anyone's obtained the double-damage one to know how that works, but I'd guess it works similar to relics (i.e. low proc rate, works on Barrage but not WSs; someone correct me if I am wrong)...
DMG:37+35 Delay:540+60 Occ.Atk.Twice
DMG:37 Delay:540+60 Occ.Atk.2~3Times
DMG:37+44 Delay:540 Occasionally Deals Double Damage
(I'm not 100% sure if the last one's +DMG is correct, but it's close)
Elemental Trials will end with an aug'd variant of the
Bateleur. You can gather the end result by comparing the trials from other weapons reported on wiki. The only ones most rangers would bother to look at are...
DMG:80 Delay:540 STR+6 R.Atk+16
DMG:80 Delay:540 AGI+6 R.Acc+16
Weaponskill Trials will end with an aug'd variant of the
Sparrowhawk.
DMG:60+21 Empyreal Arrow DMG+10%
DMG:60+18 Store TP+8
