level progress: *1-20 ranger: feats: weapon focus(rapier),improved critical(rapier),knockdown, improved knockdown,weapon finesse, blind fight,((skill focus discipline or improved initiative, I went for ii though))
*21: ranger:feat (bane of enemies)
*22-26: paladin: feat( on lvl24): armor skin
*27-30: rogue:feat epic weapon focus(rapier) max out tumble here(which would be 30)
*31-36 paladin: feats(on 32 and 36) epic prowess and great dexternity1.
*37 rogue: max out tumble and other skills you want.
note: I just wrote down the feats I took, but they can be taken in any order you want if possible.
fully buffed with paladin spells(divine favour/GMW/bless/aid/prayer) this guy has a decent ab of 61 without counting favoured enemies or bane.So that would normally be 61 + 7(on favoured enemies)=68ab.If you max your charisma you can add +5 to that in a smite making the smite ab 73 vs favoured enemies. with +6 items and haste I ended up with 61ab(68 vs fav. enemies) and 74 ac.
Forgive me for not showing all the details but I made this build a week ago and don't know everything correctly anymore.But I think I mentioned the important stuff.
