Intro
This guide is for making the best PvM summon necro possible, capable of doing every single thing in the game safely, efficiently, and with respectable MF. It assumes access to high-end gear and intermediate game knowledge on the reader’s part. This character does best on /players 5 or less (eg. you and 4 other people in the game). While he’s safe and capable in full games, he slows down disproportionately due to the build’s mechanics, irrespective of gear quality, and becomes inefficient. If you need to obliterate everything efficiently in a full game, go hdin, lit sorc, java, etc.
However at p5 or below he is at least comparably fast, if not faster, to most other builds for most content. He requires no prebuff or situational gear taking up precious space in the stash. He’s remarkably effective and versatile, there’s nothing he doesn’t do well. Yet a lot of people don’t know how to do the build properly and how good it really is. I’ve read no other summoner guide that comes close, and there's a lot of bad info out there about the build. Plenty of pros out there know the ropes, but I don’t think any have written a guide, so here goes.
Gear
Weapon: Beast double axe, fanaticism is required
Shield: Spirit monarch 35%
Helm: 2/20 circ
Armor: Enigma
Gloves: Trangs
Belt: Arach’s
Boots: Travs
Ammy: 2/10
Rings: 2x fcr ring
The breakpoints we’re hitting are 125 fcr and 56 fhr. 125 fcr is the max necro breakpoint, they share cast frames with paladins and are 2nd fastest behind sorc/barb frames. It’s vital for teleporting as fast as possible thus making the character more efficient and survivable, and the fhr breakpoint is easy to hit and aids in survivability.
You’re better off with two good fcr rings and a 10fcr ammy, the +1 on the bk/soj you could wear with a 2/20 ammy doesn’t benefit the build all that much. You’ve got a lot of stuff to make up for due to the beast having nothing but fanaticism and str. This also means that the ideal ammy is rare, giving it potentially 6 affixes instead of the 4 on a craft.
The goal is to not spend any points in str (and obviously none in dex or energy). Necro base str is 15, if your torch + anni combine to give you 43 you equip the beast double axe for another 25-40. If these 3 items rolled well enough, you’ll have 95+ to equip the travs, then it’s enough for an AP enigma. If it doesn’t work for the AP, at least try to use an elite base. DS has the lowest str req at 77.
The circ and jewelry are where your budget (b.net) or luck (single player) will really come into play. You’ll want a mana roll on at least 1-2 of those items, 800 mana with BO is a good minimum number to shoot for. You'll want a str roll or 2 also, since you'll lose the str from beast when swapped for BO and may not have enough to equip the BO spirit. Last but not at all least, the more life & resists on this stuff, the better. You definitely want max resists btw, or at least as much as you can get while you work on it. Some guides say it’s not important, those guides are for a less effective and/or budget necro.
Inventory
Gheeds, anni, torch
Summon skillers, preferably with life
Use SCs to fill out resists, raise life/mana, or boost mf, depending on needs
You’ll need one charm with any amount of fhr to hit the breakpoint at 56, with the spirit giving you 55.
Gheeds is worth it over an additional skiller. Once you have 15 skeletons, and around 20 revives with only 1 point invested, you’re fine and more skills don't help as much as with other builds. With just perf travs & gheeds, and enigma, you’ll have 180mf at level 90 with zero impact on your kill speed or survivability. MF has big diminishing returns and more isn’t as good as you might think.
Merc
Might aura (act 2 nightmare offensive)
Gface – ias jewel, with ed if possible
Fort ebug – for this build treachery is bad
Infinity – giant thresher is ideal, otherwise thresher. Highest % ED possible
Your merc’s job is to do the most damage possible. He’s 90% responsible for making the corpses you need to start chaining CE and wreck everything - this is part of why it slows down so much in full games. He doesn’t need leech, your skeletons take most hits on trash, and you can't leech most bosses.
Golem
You’ll be using iron golems, which die occasionally. Sometimes you do too, which kills the golem obviously. Thus instead of wasting expensive runewords, Iggy is made from insight. The mana regen is so important that you’ll do better with this than a pride golem, so I’d suggest this even in HC where you don’t die. Other casters can get by without meditation aura, but their spells are cheaper than max CE.
Eth insight = eth golem, mega style points. Nothing high damage, he’ll pull aggro constantly and you’ll end up babysitting him and losing efficiency. Normal eth polearms are best (halberd, scythe, etc.) Most IG deaths will be due to Nihlathak’s snakes or Diablo’s firestorm, be especially quick in these encounters to tele, tp, or exit game if it’s bad enough.
If you’re uber rich.. and crazy "eccentric".. and have boatloads of life / mana / resists from your undoubtedly Godly circ ammy and rings.. then go ahead with the pride I guess. It's definitely better, especially for bosses... if not for the mana issue, and the inevitability of losing a big runeword (a concern for us mere fg mortals). To aid in your mad quest, you could put less points in CE, making it cheaper at the expense of a bit of radius. And use magefist for the free point in CE and mana regen. Use whatever base you want, pride has no ED so it won't draw undue aggro to Iggy. The golem WILL eventually die. You've been warned.
Skills
Curses
- 1 Amplify Damage – Main curse to be used almost always
- 1 Decrepify – Has some use in ubers, and used for Baal, Lilith, and when shtf
Poison & Bone
- 20 Corpse Explosion
Summoning
- 20 Raise Skeleton
- 20 Skeleton Mastery
- 20 Golem Mastery
- 1 point in every other skill except Fire Golem
- All remaining points in Raise Skeletal Mage
Note: Maxing Iron Golem reduces his survivability. The increased thorns damage makes him pull aggro more. I spent 2 tokens and 2 eth insights learning this so that you don’t have to.
Gameplay Basics
Forget about sitting back and watching your minions kill stuff, that's not efficient in hell. If you really want to do it, make a 2nd necro for it. The plan here is to amp hordes of monsters and CE (corpse explosion) until everything’s dead. CE does half fire, half physical damage. The fire is increased by infinity, the physical by amp. Being a fire skill, its level is increased by 1 if you use magefist.
Teleport directly onto major bosses, this gets all of your minions attacking the boss and not jostling around trying to find a spot in the hitbox. It’s also helpful for killing specific monsters in crowds. Ubers on the realms would be impossible without this technique, your army would fight all the monsters instead of focusing down the bosses.
For dclone / uber tristram, revive urdars for their crushing blow. The ones from river of flame are noticeably better, but the ones in a2 palace / tombs or a3 durance will do the job. Once your gear is good and you’ve done ubers a few times, you don’t need any bleed effect to negate their regen on /p1. While learning or gearing up, or in multiplayer games, you can keep a toothrow stashed for your merc for open wounds. The PMH (prevent monster heal) on infinity works for dclone, but not ubers. I've never needed a pdiamond shield or a treachery prebuff or anything - but don't try uber tristram without at least the enigma, beast, and 15+ revives. It's not as faceroll as a smiter, you do need some gear here.
Outside of the above, revives are only useful for the ubers mini bosses, baal, and cows. For this content, just revive the effective monsters out of what’s there and explode or ignore the bad ones. Urdars are unnecessary and time-consuming for this. For other content, revives just get in the way and using them is a decrease in efficiency due to constant resummoning and the hitbox issue.
While you can efficiently do any content, the build really shines at slaying vast hordes of melee monsters since they group up so readily. Cows are a great target, and check out the act 2 tombs. Duriel’s is meh, but the other 6 have insane monster density and are a blast with this build.
