The build is insanely simple. We are using health recovery as our main heal over time stacked on top of leeching vines with minor life steal. Arctic blast is our main form of crowd control for ads, and our only burst heal. Automatic damage shields from our infused hardening enchant, and Iceheart provide even more passive healing.
Rotation:
Keep up your damage over time skills and heals at all times. NEVER cast your bear ultimate except to resummon it. Taunt everything that cannot be stunned, and stun everything else. Pre-cast shalks before add pulls so that you can apply major and minor breach early. Keep your elemental blockade down at all times, and heavy attack away. That's it! Pay attention to mechanics, keep your health up, block and dodge when necessary, and boom! Vet DLC dungeons fall before you and your duo partner or group.
Food choices:
Use bewitched sugar skulls when you need extra stamina for blocking channeled boss attacks. Use corrupting Bloody Mara for a tad extra health and damage if you don't need to block or roll dodge too much.
Potion choices:
For extra armor when you don't need the extra stamina from tri-stat potions (for example, you can use two infused block cost reduction glyphs to reduce your need for stamina from potions a lot), use Essence of Health armor potions giving health, physical, and spell resistances. This will put you at the armor cap, giving a ton of damage mitigation.
