A slightly different take on Iron Fist after the nerfs. Using chi blast as the spender and the 15% buff to damage it gives. Using m'kraan for the flat damage, crit, and chi to give us a pool that allows chi blast to be used as a high damage area/mental attack. Feel free to make it fit your play style. I sit at 47% damage reduction unbuffed, 56% buffed without an armored core. Have invuln and damage absorb from leopard and Dragon stance. You can play with the 5th talent for damage, surviability, or not use it at all and fill in with good forture thunder kick.  The cosmic 15% less spirit and 10% sig cool down line up the cooldowns in the rotation so you can get back to back seven armies sundered while using the Hydra agent medallion. If you don't have to the hydra agent you can use Magneto and adjust infinities to fit depending on gear.
