Then a few bard levels for blur, rest fighter for feats, another rogue for evasion.
Save a few bard levels for last so you can catch up on the skills UMD and perform. ( save 4 or so bard levels )
I went max constitution, after all it is for your hit points and damage so is paramount over any other stat, also it is cheaper for a dwarf to max out.... Intelligence bah.. Roll an elf
Trying to go bard with rogue skills is far too skill point heavy, trying to do it all just spells dead gimp and the amount of gear you need to carry for swap outs is a pita.
You can however max out open locks as it works off your dex score, and a locked chest you can't open because your level 3 wand of knock sucks is just torture when soloing.
( again totally up to your play style as it removes skill points from something else )
Get your reflex up, you have evasion, improved dodge, greater heroism, swashbuckler reflex bonuses, stalwart defender save bonuses... Is there a trap you even need to worry about, even on elite?... I don't think so.
You can always resurrect pure build trap fodder, well what's left of them after you scrape your boots. ( pure builds..... " but I love my old pen and paper build " )
:/ saving throw vs traps failed
I think with just 2 rogue levels even allows for the feat improved evasion in Epic feats?
Go test it out on Elite Lord of Dust or grab a rogue hireling.
Then after level 20, test again on epic levels. For me, LoD sets the standard.
If you come out as mince meat, improve your gear.
Maxed UMD and perform are the main 2 skills, heal skill yeah if you want, concentrate i never ever bothered, never took quicken, never had a problem.
Balance is also important, I tend to get that as high as possible.
Jump, don't bother, use pots or gear clickies.
You adapt your play style to suit and when in doubt , click improved dodge, jump around like a muppet on crack while recasting your displace or D door... Problem solved
The crack monkey has left the stage via D door to safety.
