I have made a chaos AAR Warlock some time ago. I planned to post it but @Willnoword made a better chaos AAR Warlock, so there was no point to it. But lately I decided to make some tanky AAR builds. I repurposed this Warlock into a chaos AAR tank. It uses typical items for chaos AAR or AAR in general. There is not much leeway in what to use. But the most important thing are the devotions that is where the additional tankiness comes from. This build already has damage reduction from Maiven’s Sphere and Possession. There is also damage reduction from the helm. This is a good base to start from. To enhance this I decided to went for Ishtak in the devotions that gives damage absorption as well. In my version I have 18 % damage reduction from the helm, 22 % damage absoprtion from Maiven, 19 % damage absorption from Possesion and 25 % damage absorption from Ishtak. That makes in total 0.82x0.78x0.81x0.75=0.39 therefore you only take 39 % of damage. Because of the lowest cooldown for Ishtak (and Mirror as well) I also use Time Dilation and Eternity Relic in addition with nice CDR from items. This also causes practically 100 % uptime for the Ritual Circle. For healing amulet with ADCtH to AAR is used, Sigil of Consumption, Scales and Bat. Half of vitality damage is converted to chaos through the belt. Build does SR 65-66 easily (it can go a lot deeper). I killed even Ravager with it (facetanking first half and a lot of the second half). But it kills significantly slower than my previous tanky aether AAR Spellbinder (aether is just better damage type than chaos generally). Ravager took 3 times as long!
Build uses one monster infrequent item - Alexander’s Legguards. You want bonuses to chaos damage, OA and DA. Crafting bonus on the helm is to freeze resistance.

SR 65-66 is very easy. I guess that this build can do deep SR. I don’t push my characters higher but it can go a lot higher if you are a skilled player. I don’t play Crucible so I don’t have a time number for it.

Maybe all are doable but I only killed Ravager (I like his helm). Others I don’t care about. You can facetank him for the first half of his life easily and for a lot of his second half as well but sometimes you have to disengage and wait for cooldowns to end. Be aware that facetanking him is not easy. You have to time everything correctly for couple of minutes. It took around 10-11 minutes to kill him. Although this build is tanky the aether version is just better for killing Celestials (3 times faster! with aether AAR).
