i made this character in 3.5 and it was one of my top 3 characters i've ever built. i was trying to remake this character for pathfinder and found that an oricle is your best bet, they have clouded vision which will make your day as you level. and battle oricles are pretty sweet if you check them out. you can lose the spell casting with an archetype in one of the ultimate books, if you dont want to cast. i know this is a pretty old post so i will make the build as i would play it, hopefully you check these old threads.
also i remembered a character i built a while ago that that is a fighter/wizzard that uses darkness and obscuring mist type spells to negate vision completely allowing my character to fight unhindered with blind sight.i think i went samurai/wizzard into eldritch knight.
took blind fight and used a magic item to gain blind sight... i will have to find that item again.
one more option would be magus kensai archetype, using darkness and obscuring mist, similar to the previous concept, but no multiclassing with massive armor bonuses with diminished spell casting.
