Skill Rotations By Encounter Type

- Mobs without elites (like overworld events): Minions look after it solo.

- Mobs with Elites: Fire a Bone Spear at Elite, heavily damaging it (and which makes it vulnerable) while killing some ads. Next, trigger Blood Mist to obtain tons of Corpse Explosions to melt the rest of the mobs and Elites, whilst charging the following Bone Spear cast with Consuming-Corpses-increases-core-skill-damage affix (which lasts until the next cast, whenever that's). Next mob gets hit through the super-powered Bone Spear then Blood Mist / Corpse Explosion clean up, and so on.

- Dungeon / World Bosses: Skeletons/Golem soak damage and do a lot of their own (because of masteries and additional skeletons from Affixes) when you use Dodge and Blood Mist for immunity if needed. Alternate Bone Splinters and Bone Spear casts; Bone Spear does heavy damage, while Bone Splinters + Mages quickly refill Essence to ensure the next Bone Spear cast gets a max bonus in the Extra-Damage-with-high-primary-resource affix. When necessary, heal / re-cast skeletons from corpses generated by skill attacks and reapers; otherwise needed to heal / re-cast skeletons, can Blood Mist into the boss and Corpse Explode these, there will be a lot because of reapers and Hewed Flesh creating extra corpses.

There is enough defense in the Barrier, Damage Reduction, and Bubble affixes to face up to the Butcher with minimal potion use (1-2 for the most part), with enough DPS to melt him within about 20 seconds. Ashava took longer, but good Blood Mist timing and also the occasional re-cast of skeletons kept the boss from killing us, in the end, took it down with minimal help from the lower-level party members we were left with.

We're sure this is of limited relevance in higher World Tiers (minions will most likely not hold as much as higher Tier boss damage), but it is unstoppable at Lvl 25 at Veteran Tier.
