Necropolis Poison Holy Relic of Conviction Necromancer (April 22nd snapshot)^3.24

Notes

PoB does not support setting the Relic count to 3, so actual DPS is basically 3x the value shown in "Total DPS inc. Poison"

10% shock is an extreme lowball of what Storm Conduit can do, but there is also downtime on the shock
Pale Seraphim's damage bonus isn't accounted for because I don't know how reliable it is, I do see it happen a fair bit though

Minion Taunt and Molten Shell are not accounted for in any EHP stuff

Resistances are extremely overcapped for blue altars+elemental weakness, Chaos Resistance is also overcapped for hex/curse reflection
- Note that Resistance Catalysts will be added in the future to fully overcap the chaos resistance

Rings could have Minion Damage on them from Redeemer Exalts. Min Endurance Charges are really good for PDR + they seem to work in "can't gain charges" map modifiers

Spectres: You can have 3 once the gem is level 25 (21 gem, +1 ashes, +1 shield, +2 corrupted helmet)
- Wild Bristle Matron can be found in Harvest. Has a stun attack, 40% action slow warcry, and is very tanky
- Pale Seraphim can be found in T17 maps or from Beyond Allflames. Has an attack that can increase enemy damage taken and slow them, also very tanky
- Storm Conduit I believe is only from Allflame Ember of Valako, it may not be available next league. Beam guarantees a shock, very tanky, huge amount of ES
Spectral Leader is nice Quality of Life but very squishy and doesn't actually give damage so I dropped it. Malevolence made the aura 100% uptime though.
Arena Master I'm not a fan of, low uptime on buff and the buff seems to actually make you take more damage.

Abyss Jewels were all just rolled using Harvest yellow juice to reforge Chaos until I got life + decent poison chance
- I sold other jewels that were decent enough poison chance with other things. 15% Poison Chance with nothing else was automatically able to sell early on
- May not be the most efficient way to do this, but it works and it doesn't usually take long, I was farming Harvest anyways

20/22 gem is better than 21/20 if it gets you to the 52 quality breakpoint. 21/22 is ideal.
- It is recommended to only corrupt Holy Relics using the Atzoatl Gem Double Corruption altar.

Cluster Jewel was crafted just using alterations to hunt for 35% passive effect (this affix has no tags so there isn't really a good way to target it)
- 35% passive effect is a prefix, so make sure to augment if you only get a suffix that is decent

AG gear: Mask of the Stitched Demon, Garb of the Ephemeral, Windscream, Asenath's Gentle Touch, Kingmaker or Dying Breath
- I believe Dying Breath is technically higher DPS than Kingmaker's Culling for this build, but Kingmaker gives us Fortify when it is in range. Rarity also a nice bonus
- The helmet could be changed to give far more DPS, but the Guardian needs HP recovery and the only other slot that could change is Garb of the Ephemeral.
   Dropping Garb would be a massive defensive loss especially due to the prevalence of action speed slow in endgame bosses, and crit modifiers in Necropolis+T17.
   Bone Barrier + Mask of the Stitched Demon basically makes it unkillable by giving it 50% regen/s unless it somehow gets bursted by a ton of damage in a short time.

Timeless Jewel would probably be better to socket on the right side of Necromancer and converting the Pain Attunement keystone into Divine Flesh instead.
- I didn't bother optimizing my Timeless Jewel that much when I added it, but I might get a new one in the future.
- The Timeless Jewel on the right hits 7 small nodes instead of 5, although the tree could be adjusted to do the same on the left.
   Right side has a better starting node by giving a slight bit of flat ES + I'd like the extra 5 cast speed from Arcanist's Dominion for Despair, it is noticeable

Quartz Flask is only used because of Phasing, nothing else since we're suppression capped without it. A lot of content with high mob density feels really awkward to run without it.
Haven't tried dropping the Jade Flask, a Taste of Hate or Basalt Flask could definitely be an option.

T17 mods to not run:
- Rares/Uniques remove 10% life/es/mana on hit - DO NOT RUN. As far as I can tell, this affects minions. If you want to attempt this, desummon your AG and make sure your minions have leech, but I can't see it going well.
- 15% of damage dealt to totems taken from summoner's life - DO NOT RUN. THIS AFFECTS MINIONS (also traps and mines btw lol) even though it only says totems. You will probably die.
- Volatile Cores - Technically runnable, but these cores are VERY OVERTUNED. Poedb says they do up to 67k base damage which can't be suppressed or blocked. With a little damage scaling this could probably 1 shot AG
- Players take increased damage per ally - Anti-minion modifier. Minimum 140% increased damage taken on this build, GGG why
- Players cannot recharge ES - Haven't actually tried but it should affect EB so it should be unrunnable without ES leech or ES on hit
- Reduced Effect of Non-curse Auras - self explanatory, losing a large amount of your aura effect has always felt bad; I don't even run this on low tiers
- Union of Souls - only run if you plan to ignore everything other than the boss. Too annoying, and any source of DD will do way too much damage and could easily kill your AG 
- Not a modifier, but Charred Beast packs: ALWAYS replace these with an Allflame!!! This is basically a super OP Stygian Revenant and the DD will easily kill you + AG.
  Charred Beasts basically always show up in Abomination Map and can sometimes appear in other T17 maps too.

Mods to be aware of:
- Meteor on Flask Use - Without automated flask usage, easy. With automated flasks, be careful.
- Less Recovery Rate - really not great for Divine Blessing mostly but possible to run, I avoid this 
- Marked For Death - Not recommended. Poison kills count as you killing them, culling from Kingmaker can cause you to kill too. If the minion kills with a hit this should have no effect though
- Awakener's Desolation - just be careful of the pools, they disable regen. very runnable
- A lot of speed/aoe/projectiles - I think this is self explanatory for every build on bosses.
- Poison avoidance - self explanatory, though runnable
- Ele reflect - be careful of flame dashing through too much stuff, otherwise fine, also make sure to resummon Storm Conduit later since it will likely die. You can take Ancestral Bond technically to prevent Ele Reflect deaths to Flame Dash
- No damage for 4 seconds every 10 seconds - Just annoying as hell. Runnable but extremely unfun
- Debuffs expire faster - this affects wither. still runnable
- All the standard stuff with damage mods on maps which should be fairly obvious.

I use the max res sulphite nodes + shrines + enemies can't be ghosted + the -25% enemy damage keystone on Atlas for T17 bossing. No explicit map mod effect for that tree.
The sulphite nodes are highly recommended since it also gives movement speed.
Einhar is nice to add since it will give your minions life leech if you don't have any; his damage is negligible.
The -25% Enemy Damage keystone is just extra safety, definitely possible to do T17s without it.
