Poet's Pen Volatile Dead Build Running Uber Lab - Path of Exile
The overall goal is to first hit your 4 or 8 attacks per second (not more) breakpoints depending on taste/playstyle. At 8 attacks you cast 4 spells 4 times a second (16 spells/second). Your generic clear setup is Unearth -> GMP -> Immortal call and Volatile Dead -> Elemental Focus -> Bodyswap. There are multiple single target setups. I like Unearth -> GMP -> IC and Volatile Deadl -> Concentrated Effect (or detonate dead) -> fire pen. If you have some/enough AOE fireballs are another great option with overlapping detonations with volley, which results in very high single target damage. Firestorm is very usable, or any other spell you feel like spamming.
Once you hit your 8 attacks per second breakpoint, you can go for luxury gear by using the new CDR roll on belts to scale the damage. 20% cdr belt = 20% more casts/damage but also requires even more attack speed. If you just go for the 4 aps playstyle (just volatile dead in one pen), you have somewhat lower damage, but almost no gear requirements.
There are three main ascendencies to use Necro, Heirophant, and Slayer, although this setup can be done with any class you like (Berserker and Pathfinder are also great).
Perm immortal call is achieved through Romira's Banquet + Voll's Devotion (or heirophant). The goal is for immortal call to last slightly longer than its cd (3 seconds) so that it gets constantly refreshed. This is super easily achievable on any class.
I am playing a necromancer because of the additional layer of defense through offerings and the massive free attack speed stacking from spirit eater (easy 8aps). Volatile dead and body swap count as consuming a corpse, so this node almost attack speed caps you by itself. (my current build: https://pastebin.com/WpN8QgTD).
Overall I feel that heirophant is the best starting class if you can't afford voll's devotion, while necro gets free attack speed. End game you're better off as slayer, pathfinder, berserker, or heirophant (low life).
Slayer has significantly more damage and the over leech is really really nice. I'm currently respeccing a lvl 81 slayer to try Shaper out.
Heirophant does not need voll's devotion, which is a big plus. The reason to go heirophant is to go low life for more damage and has a free amulet slot.
Your main attack is Frenzy (20%)-> Faster Attacks (20%)-> Culling Strike (20%). This setup alone gets you to around 4 attacks per second.
I use blood magic on the attack and a level 2 enlighten for triple purity. You can also use haste for attack speed, or a higher level enlighten to have some mana free to cast spells. Insanity gloves are a must for the build if you want 8aps. No other links are needed, feel free to wear Kaoms chest and or boots. The slayer version with kaoms has 8-9k life with perm IC and 80%+ all resist plus leech.
I've killed Elder and guardians, but haven't tried Shaper yet. The build feels beyond OP and you can speed clear red maps with most mods in minutes with bodyswap.
The Poet's Pen looks really cool, it seems pretty good to level with. Any thoughts on that? For a lot more Path of exile 3.1 Builds, you can check out https://www.u4gm.com/path-of-exile
