Hi TheSquid! Thanks for posting!
I really like this build idea. It looks extremely difficult to kill!
Combined with your high sneak attacking rogue teammate who can supply some buffs and spells with UMD, traps, lockpicking, stealth and other skills, you have a deadly combination who can solve so many different challenges and puzzles in a PvM environment.
The implosion resistance sounds very strong but also well worth obtaining, dying all of a sudden with 800+hp and great damage reduction from DD is not a nice feeling especially when protecting others. I’ve had it happen in a party! Ouch!
Dev crit resistance is also valuable too which this build has (most characters get a Dev Crit Fort DC around 40-45), although usually no-one except a crit immune character is going to want to melee with those enemies.
Curious if you were you tempted to to drop starting Con to 17, put Dex to 14 (for +1 to reflex) and Int to 14 (for 43 more skill points, which could be put to cross class tumble for +4 AC)? You can then drop one Epic Toughness for a Great Constitution. HP will then be 804. Still get the starting Str of 16 which is nice to carry stuff, equip heavy armor and tower, and hit things.
