I'm intrigued by utilizing the Warpriest's Burden of Sin enhancement, and thought it would be fun to make a tank based around holding opponents on them with intimidate, and piling draining effects on them as mobs try to pound away on a high CON heavily armored tank.
Burden of Sin: 15%/30%/45% Chance on Being Hit: The enemy that struck you gains one stack of Burdened. (-1 to Strength and Dexterity. This effect stacks up to 10 times, and loses one stack on expiration.)
Combine with the Barbarian Ravager's
Do You Like Pain?: When you are hit: [20/40/60]% chance attacker loses 10 AC.
Items like:
Bracers of the Demon's Consort
Other enhancements like:
Demoralizing Success: Passive: You gain +30 hit points and +10 healing amplification. When you score a vorpal hit in melee, you inflict Crushing Despair on nearby enemies for 30 seconds on a failed DC 20 Will saving throw. You then inflict Vulnerable Will for 15 seconds, regardless of the Crushing Despair saving throw.
I thought i'd go Dwarf for extra CON, and use a shortsword with some Con damage effect on it to swing away and take enemies down down down as everyone else pounds away on them..
I'll probably throw something together this weekend and give it a try.. see what happens.
