Eagle Eyes +8 > Helenid +8 > EIB or IB +8 > Helenid +7 or Eagle Eyes +7 > Horn Cross Bow +9 > Chitin or Enion at +7 > Iron bow +7.

Prices are higher on uniques bows, so for a decent price you can get hxb+9, which has 122 ap and can be used whit wes.

Is useless to go pk whit armor below +7, +6 wont give you enough ac or dex.

This thing u didnt put and i think is really important, Make a +7 str paper set, this will help you carry styxs and pots while pk.

When you see a party of mages use magic shield first, then atack them, if they nova like crazy u will get knight noah chances to survive this way, otherwise u pretty much death.

And finally...the jewerly...

Well of course rol is always an option, but it is simply too expensive ill put a list of jewerly that are gg for archers xD

Rings

Elf rings +1/+2 ( ubber dex, magic resistance, cheaper than most earrings)
Kek rings +2/+3 ( decent dex, great resistances)
Rol +0/+1 ( expensive like hell, great bonus, low dex for an archer tought)
Legionary Band +0/+1( Rol price, rol like bonus, but better resistances)
Rom +0 ( good to combine whit elf or kek to boost a lil ure ac and hp, cheaper than rol or roc)

Pendants

Ammy of dex +0/+1/+2 Great dex, cheap price.
PP +1/+2 5 less dex than ammy of dex, far better bonus, lil more expensive ( the best choice for an archer)
BDK +1/+2 A cheap choice, cheaper than the other two..but worst too.
WP +0/+1 More expensive, less dex but higher chance of survival.

Belts

Youre an archer...you just need elf belt xD

Earrings

Silver earrings are the best unique option, EMEs are expensive and got low dex, dex +9 earrings are a good way to start.
