Many of your Skill choices depend on what Legendary Aspects and Uniqueitems are available to you. This enables all of the shards to hit the one mob you care the most about.

If you run into an elite pack or boss, it's best to engage them near a wall, column, or other environmental object that you can reflect your Bone Spear off.

You can shoot offscreen, or stun using Corpse Tendrils on a far away corpse before spamming down the pack.

But when fighting a tough elite pack or boss, you will want to carefully engage from a distance. When fighting regular mobs, we engage with a run-and-gun style that's fast and free.While you can force your way through some enemy blockades, the slower movement speed of the skill can often lead to a wall of enemies waiting at the end to bop you. It also completely removes Poisons and other DoT debuffs, so it can be used mid-fight to reduce incoming DPS. Make sure to use this skill sparingly, so you have it available in truly dire scenarios. Blood Mist helps to remove CC from your Necromancer if staying stuck would lead to your untimely demise.This also activates the important Offensive Aspect of Grasping Veins. You can also use Blood Mist to get a Corpse. Start the fight using one Bone Spear in order to create one corpse.Prep the fight by casting Decrepify so all our hits proc cooldown reduction on everything.Decrepify is important for reducing our cooldowns and makes us more survivable at the same time.It's especially notable as one of the few pixel-pull skills in the game. It also triggers Aspect of Grasping Veins, which is handy from time to time for extra damage. Corpse Tendrils Slows, Stuns, and pulls every monster (except Bosses) into a single space so that all of our AoE damage becomes more effective.

Bone Storm allows us to stay safe early in our progression with a shield using the Defensive Aspect of Shielding Storm on our Leg or Chest slots.

We also take Ghastly Blood Mist to generate a few extra corpses so we can Corpse Tendrils at will.

Blood Mist is the only Skill the Necromancer has to provide Immune (which also provides Unstoppable).

Our Best In Slot generation setup with Resource Aspect of Exposed Flesh keeps us completely full.

Bone Splinters for Essence generation.

The second damage component can make positioning important when fighting elites or bosses.

Bone Spear is our main damage and hits enemies with both the main hit and reflected shards.
