It has been a long haul but finally my tank is racial completionist. So I could finally stop being a sorc.
Her effective hit points are 69,038
Self Buffed intim is 143.
The pic is 100% self buffed.
The build is very easy to make. Be warned though it is a dedicated tank. Don't expect to ever get a kill with it.
PDK - 12 Paladin - 4 Fighter - 4 Artificer
Stats - CON and CHA and 13 Dex. Level ups go into CON, You need to have 13 INT by time you take your 4th artificer level.
Feats - Dodge, Mobility, Spring Attack, Combat Expertise (level 4 artificer feat), Toughness, Epic Toughness, Scion of Celestia, Bulwark of Defense, Epic Reflexes, Force of Personality, and MOAR TOUGHNESS, The paladin religious feats should be Helm if you are PDK. I also took dire charge. I have been playing with trying to make it work. ( I need the stunning DC trinket )
(For even more HP just skip taking dodge, mobility and spring attack and instead take MOAR TOUGHNESS)
Level Order - Does not matter much, Just make sure that you have enough INT for combat expertise by time you take the 4th arti level.

Enhancements - 44 in Sacred Defender, 23 Stalwart Defender, 13 in Renegade Master Maker. Just take everything that increases hate and armor class and MRR, PRR
If you have no racial AP you will need to take fewer in Sacred Defender to get CHA to hit and damage from PDK tree.
If you are Racial Completionist throw some points into PDK to get MOAR AC and Heal AMP.
Destiny - Guess which one adds MOAR AC ?
I have been using this build to tank in R10 quests and it stands up just fine. It has NO DPS, Your party is the DPS. You get to heal your team (my cure mod was hitting team mates for 250 and renewal is boss). GRAB all the aggro you can. Keep those red names and reapers bouncing off you while everyone else hammers away.
I have also run a variety of reaper raids with her with great success.
Future Plans - I still haven't done Heroic Completionist .... That would add a little. It would mean grinding 8 more lives though. And after having done 36 in the last year I need a break from TRing my tank. I also only have 61 reaper points. As I add more from tanking everything on r10 I will get even MOAR HP.

I also have only 1 barb past life ... 2 more would add MOAR HP.
For those people that do not have a racial completionist but want to make a similar tank. The build still works fine. Just 1 - Work on getting your epic past lives - the 12 martial lives add a lot of AC and the primal lives add a lot of HP. Any race should work ok ... but I felt PDK would be best due to CHA to hit and damage. But as you deal very little damage anyway anything should work.
