I haven't found a Kridershot yet (although most everything else) so I'm using Entangling/ShockCollaras a main and ElemArrow/FrostArrow as a secondary. My primary finisher (and used as a main hatred spender except in a line of mobs) is Cluster/LoadedforBear and it works very well. I've rarely played Entangling(or Shock Collar)but it is very powerful as it refreshes itself regardless of how many mobs are chained. I can turn 180 degrees and Entangle more mobs and the ones behind me are still snared/taking damage. Works well in groups (T5/6) and the +Lightning items (Thundergods, etc.) make the damage ticks way up there.
I have the chest that allows 3 Wolves (Cloak of the Garwulf) and I've never enjoyed a pet more. They do 350k+ damage hits normal and crit much higher (x 3 wolves, million damage combined minimum/tick); as a bonus the 3 wolves tank most anything and (for the time being) have no health hence never die. Steady Aim, Cull of the Weak, and Night Stalker are my Passives although I may try Blood Vengeance (some confusion if you are at full health if you get the hatred/disc but Ishould test it out)and since I don't really need more damaging skills I took Lingering Fog and Gloom. Lingering drops my aggro and the wolves pick up the boss/elite right away.
I will miss my Calamity when I find Kridershot but I won't hesitate to use it. My Frost Arrow crits for well over a million so spamming it will be devastating.
