So I want to know is what this guy is saying possible? For the arcane wizard? and if so how can I some how get that on a ranger class?
"For the light-armor crowd, Warforged can basically start the game with a pocket Mithral Breastplate -- which itself can be further improved with feats for even higher DEX bonus. With the aforementioned Docent, this could give you a virtual +6 Mithral Breastplate with max DEX 6 in the bank just for deciding to play a Warforged! Great for Rogues, Rangers, Evasion tanks, Bards, TWF builds... and arcanes!
That's right -- as a Warforged, you can be an arcane-with-AC. Warforged enjoy a line of enhancements that allow them to reduce ASF, as well as docents which serve the same purpose. If you're willing to accept some of the pain of ASF through the early ranks, you can roll a caster that runs around in a nice +6 Mithral Breastplate! And honestly, the pain is not that bad. Combining enhancements and a Lesser Arcane Sigil docent, and you're already at only 5% by level 2, and should be able to fairly easily hit 0% by level 7. And, if you're a wizard willing to spend a few feats, you could go high-DEX, take dodge and mithral fluidity, and be eventually running around with a 45 AC. (10 base + 11 armor + 6 DEX + 6 shield (mithral light) + 5 protection + 2 chaosguarde + 3 chattering ring + 1 dodge(feat) + 1 self-haste"
