if u can upgrade it then much better ^^ snipers benefits alot on this low cost bow
i think u can already farm ferzen for some iron armor
or farm some chainmail in cockatrice then do the damascan armor quest in rokoko that should give u a decent amount of hp
seahorse bangle of if u managed to earn a few million spina buy ring of tide ---this will give u aton of hp since ur going the warrior branch route
on ur stat u can add a bit of vit maybe 30-50 points to boost ur survival abit
---i dont think u mentioned what type of sniper ur going for though
agi dex crt (thimble/archer glove user) special bow autoattack sniper
agi dex str crt (adamantite arrow user) special bow autoattack sniper
dex crt str (adamantite/thimble/archer glove) arrow rain -> area rain/crossfire sniper
this are the pure dmg builds ---add vit if ur feeling like ur dying at every hit
and the most common advice is to gather elemental bows and elemental xtals(for weapon and add gear)
