read title. i dont care how expensive i just want a goood character.

Hdin, Bvc Barb, Fire Sorcs are all pretty good pvpers. Your making a generic question so its hard to answer as every pvper has its own specialty. Make a FOH, they practically own in pvp 99% of the time.

do you know a specific godly build to a foher?

Look at guides here if we have any or on d2jsp.org

ghostsins(ww/trap) and v/t ( foh/smite) are very godly heroes

libby, mage, or hdin.
