Got another build for you guys, spines/ice.
Energy Absorption is on a 17 second cooldown, endurance will never be a problem!
Smashing&Lethal defense: 49.8%
Fire&Cold defense: 39.1%
Resistance is definitely not the greatest but I never paid it much mind since Energy Absorption also boosts your defense even more, and you can stack the ability twice.
Incarnates are completely up to you, but I would highly recommend Barrier or Rebirth for the Destiny Slot
