Because of these skills in the subclass tree Arcane spirt( gives you armor and massive recovery ) Divine order ( gives you massive armor to match your recovery score ) Energy drain( used with next 2 skills ) embrace the void ( triggers energy drain on spur or grenade damage ) Life steal ( kills an enemy with energy drain restore a large portion of your health ) The hunger ( increases the duration of energy drain ) Soul rip( energy drain redused the cd of your super ) Seems pretty fun
