Necromancer Bonespear Guide

Viability / Purpose of the Build

Bonespear/Teeth is one of the most simple skills there is for Necromancer. Especially in smaller corridor maps your bonespear and teeth will mow down everything. You will mostly be using Bonespear, until you get level 40+ skills and have an inventory full of 3% Magic Damage large charms.

Skills

See picture for skills. Max Teeth, Bone Spear, Bone Armor and Bone Spirit. Enough points in Golem Mastery for 3 golems and put the rest of your points into Blood Warp. Put as many points in as needed to get the lowest cooldown on Blood Warp as you can with your current +skills.

When you have enough skills, usually in endgame gear, you can use a Purity Iron Golem. This gives you the Prayer aura which will help with your life sustain. You will use 2 Blood Golems and 1 Iron Golem in this case.

Attributes

Get str/dex for gear, rest in vitality. You can prepare for a Darkforce Spawn or Trang-Oul which needs 106 str.

Endgame, you will get str/dex for gear, vita until you hit around 11-1200 life after BO, the rest goes into energy to boost your Bone Armor.

Gear

Early and midgame you can stick with 75 FCR, but endgame try to prioritize 125 FCR.
Endgame game will get expensive because because you basically need +1 slams everywhere to maximize your damage.

Early Game Gear

This gear consists of a +3 Bone Spear Wand with White runeword and +3 Bone Spear Necromancer shield with Splendor. Best spots to find these bases is big density areas like cows or flayer jungle. Preferably no MF and a low filter strictness.
Add a +3 Poison and Bone amulet and you end up with +12 to Bone Spear. A Wormskull, Magefist/Trang-oul gloves and Spirit Shroud armor can add another +3 and FCR. Fix your resistances with random charms.
You can also use Heavenly Garb armor for the Sanctuary aura, range is 12 yards and ranges from -7 / -9 Magic Resistance. You will have to fix your FCR to still get to 75 though.
You will need some mana after each kill, you could craft 2 Caster Rings, put 2 tirs in your helmet or use a pair of Silkweaves.

Check out THIS LINK for the early game skills and gear. Sockets, life/mana after each kill and +1 all skills are the slams you're looking for.

Mid Game Gear

Midgame we could go full Trang-Oul with a Boneshade wand. The full set bonus is hard to pass up. PDR, Resistance, +Skills and lots of FCR.

You can also use an upgraded Skull Collector staff, Shako, Viper and random Arachnid Mesh.
Instead of the staff you can also use a Boneshade and Darkforce Spawn.
Easiest way to increase damage is plain Poison and Bone Grandcharms and a Torch.

Check out THIS LINK for the mid game skills and gear. Sockets, life/mana after each kill and +1 all skills are the slams you're looking for.

End Game Gear

This is where it gets expensive, +1 Boneshade, +1 Darkforce Spawn, +1 Viper, 20 FCR Arachnid, +2 Necromancer/20 FCR circlet and Occultist golves.
If you want to use a +1 Arkaines, you need to get 30 more FCR somewhere else.
Make sure to socket some maek/laek jewels in the Boneshade, or other sockets you have free.

End-Endgame you can chase the Unicorn. Maybe you craft or find an offhand with +5/+6 to Bonespear/Teeth. But good luck finding those and then slamming +1 AND getting two sockets.

Check out THIS LINK for the end game skills and gear with Skillers.

Check out THIS LINK for the end game skills and gear with 3% Magic Large Charms.

Skillers vs 3% Magic Large Charms

Initially, it’s best to start with Poison and Bone Grand Charms, but for Bone Spear and Teeth, once your skills reach around level 40-45, a full inventory of 3% Magic Find Large Charms will actually provide more damage. However it gets a lot harder to keep your resistances up.

Advice is to keep two plain ones and check when upgrading gear if the two Large Charms are more damage overall than the Poison and Bone skiller.

Mercenary

Early on the Act 2 is ol' reliable, the Defiance aura helps with damage taken. An Insight polearm will help with your mana problems.

Late game you can use Act 4 Light for the Sanctuary aura. Only start using him when you can give him enough +skills to gain the maximum effect of the Sanctuary Aura. Give him a Mang Songs, Shako and Arkaines with +1 slams and an Arachnid Mesh. Make sure he also get 125 FCR.
If you are really struggling with your resists, probably because of the Large Charms, you can swap out the Mang Songs for a Zenith runeword staff. This gives you and your mercenary the Salvation aura.

Leveling

Max Teeth for strong early damage, it's very mana hungry so get those mana potions. After that, start maxing Bone Spear, then do Bone Armor for extra survivabillity. Use Golems/Blood Golems or Revives as a tanks. Finally, invest remaining points into Bone Spirit to finish up the synergies.

Leveling gear to look out for, or make, would be Nadir in a helm for mana after each kill. Then look out for the usual leveling gear Stealth, Ancients pledge, Rhyme/Splendor, White, Lore, Wormskull and an Insight on your mercenary.
Most importantly though, look for white wands and offhands with +3 bonespear or +3 teeth. You will want to make white and rhyme/splendor in these as soon as possible.

Although it's possible, its a lot easier to level as either clays/bloods or mages/revives and swap over to bone as soon as you have a bit more gear.

Farming

Early game gear can easily farm Pits and Chaos Sanctuary.
For T1 maps you can run Sewers or Arreat Battlefied, T2 maps like Demon Road and T3 maps like Pandemonium.
