Dunt put anymore then 1 pt in energy shield, i think ur items will boost it up to lik 60% absorb. TS is kinda lik ur backup skills, wen ur melee attacking him the TS could help u dmg him quite a lot.
For the Cold Armor, Im thinking Frozen Armor for saving u some skills, but this skill lack dmg to any melee, or Shiver Armor which dmg them, but its quite lil dmg.
