Excellent dex advice. I would like to add that your vit should always be twice your level for efficient soloing.Stats
Str: 155 - if ur dex build, leave it for now
Dex: 300 - leave it its enough for now and u dont even wear golden ow quiver which adds 75 dex
Foc: 10 - higher it when needed
Vit: 140 - higher it now
Skills:
Sharp Shot: 25/25 - good
Steady Aim: 29/25 (grand ring) - good
Bolas: 25/25 (fabled ring) - as for soloeing and not bossing, higher it only to the lvl u need it to be
Conceal: 25/25 (grand ring) - useless .... waste of pts
Light Heal: 29/25 (grand ring) - good
Rapid Shot: 8/25 - lower it to 1
Everything else: 1/25
if u got somehow extra pts as i see (if u will lower rapid shot to 1 and wont use coneal) u could max defensive spikes for extra dmg, good with dex build, awesome for ow bosses (cuz they're fast attackers)
all what i recommended is for dex build since i guess my ranger is around ur lvl (90) and even with almost no armour (dmg armour, lesser solstice, golden helm, royal wyrmfang and grand talon bracelets, heroic gloves, boots, ammy, ice quiver and skills rings) and hes doing fine soloeing
if ur not dex builded, then dont listen to a word i said, and get frozen (except gloves and maybe boots) when u can
I hope your kidding. Although to add a little summat... take say 55 off strength (keep at least 100 str) and put it all on vit. You need it there more than str.
