[POE2] 0.5 - Machine Gun Turrets Infernalist - A Bonestorm Spell Totems Guide

Storyline / Context

• This video is a Path of Exile 2 (POE2) build guide.
• It doesn’t follow a narrative plot; instead, it presents the build as a leveling-to-endgame progression (“playable around end of campaign into early mapping”).
• The focus is on how the build mechanics work.

Gameplay Story (how the build “plays”)

• Core theme: an Infernalist build using Bonestorm + Spell Totems.
• The goal is a “machine-gun turret” style clear and boss setup.
• While it may look simple (“copy POV”), it has important mechanical nuances that can break the build if misunderstood.

Gameplay Loop (main actions)

1. Weapon set 1: Place Spell Totems linked with Bonestorm.
2. Rotation (repeat):
   • Totems → Flame Wall → Totems → Flame Wall
3. Extra burst for packs/bosses:
   • Add Mana Tempest periodically to massively increase damage/clear speed.

Core Build Concept (why it works)

1) Infernalist + Demon Form

Ascendancy provides:

• Strong crit damage bonuses (works well with Bonestorm’s crit interaction)
• Demon Form damage and cast speed
• Free Spirit, enabling low-cost totem placement via Ancestral Bond spirit reservation

2) Weapon sets: utility vs damage

• Weapon set 1: Dedicated to Bonestorm totem damage & cast rate
• Weapon set 2: Dedicated to “keeping the engine running,” including:
  • Power charges / Endurance charges
  • Defense + sustain (higher regen, block chance via shield, mana recovery)
  • Enables Demon Form sustain and Spell Totem mana sustain

3) Snapshotting (crucial mechanic)

• Spell Totems snapshot the stats from when they’re cast (weapon set passives/gear at placement time).
• Because of snapshotting, Bonestorm totems keep the relevant damage profile even after weapon swapping.

Key Mechanical Interactions & Strategies

A) Rapid Bonestorm firing (“machine-gun” feel)

To make Bonestorm fire faster, the build stacks:

• Cast speed
• Especially “Chance to fire 2 additional projectiles”

Progression described:

• Normal Bonestorm channels more slowly (one-at-a-time behavior).
• With additional projectiles, it effectively channels multiple at once.
• Goal: reach 100% chance so it behaves like a Multi-shot effect without downsides.

B) Totems without power/endurance charge costs (Ancestral Bond)

• Normally Spell Totems need charge costs.
• With Ancestral Bond, totems reserve 75 Spirit per totem instead.
• Suggested tuning:
  • 2 totems is enough for most mapping
  • A 3rd totem for tougher moments (bossing / difficult encounters)

C) “Explosion power charges” without consuming them

• Bonestorm can use power charges to scale explosion size.
• Key interaction:
  • If you have power charges on your character, spell totems fire as if using power charges.
• They effectively maintain explosive behavior without consuming charges, as long as you have at least one power charge.
• Damage scales up with your maximum charges.

D) How power charges are generated (the engine)

• Weapon set 2 handles charge generation via:
  • Infusion of Power (grants a power charge when an elemental infusion is consumed)

Infusion setup:

• The build consumes infusions via:
  • Flame Wall consuming lightning infusion, becoming Electrified Flame Wall
• Lightning infusion comes from:
  • Verisium infusions via Powered by Verisium runic ward interaction

Automation to avoid manual casting:

• Wolf Pack + Cast on Minion Death repeatedly casts Powered by Verisium
• Depends on tuning:
  • wolf HP + your life so the minion pack can trigger low-life instant deaths

Important caution/tuning advice

• If your life is too high relative to wolf HP, Minion Pack won’t set up correctly.
• If damage/timing is off, wolves may not reach the low-life threshold.
• Fine-tuning options:
  • adjust Wolf Pack level
  • optionally use alternatives like Minion Pack 2 if needed

Low-Life / Pain Attunement / Sustain Tech

A) Keeping low life consistently

• Uses life reservation so you’re always low life:
  • targets 75% max life or below
• Benefits:
  • Pain Attunement (more crit damage)
  • access to low-life-focused supports (Execute 3 is described as less important here)

B) Rise of the Phoenix for Demon Form sustain

• While on low life, Rise of the Phoenix provides extra max HP regen per second.
• This extra regen is described as “huge” for sustaining Demon Form.

C) Charge/weapon-swap endurance tech (“Emergent Protection” concept)

• The guide describes an “exact low life” method to gain an endurance charge periodically via:
  • Emergent Protection (ancient augment)

How the trigger works:

• Weapon set 2 has more max life than weapon set 1.
• Swapping changes whether you are just above/below the low-life threshold.
• You repeatedly exit and re-enter low life on weapon swap to trigger endurance gains.

Critical warning

• Ensure weapon set 2 has higher max life; otherwise, you might not be considered low life during set 2, breaking Pain Attunement and other low-life benefits.

Demon Form requirements (survivability constraint)

• Demon Form provides:
  • increased cast speed
  • more spell damage at max stacks (but it only maintains the smaller capped stack version)
• Main downside:
  • at max stacks it drains life per second
• Strategy:
  • sustain entirely through heavy life regen in weapon set 2
• Explicit map restriction:
  • avoid maps that reduce life/energy shield recovery unless you have extremely high sustain.

Mana Sustain (so totems keep firing)

• Weapon set 2 prioritizes mana recovery via:
  • mana regen on scepter
  • Lava Spirits
  • mana recovery rate on tree + scepter companion idol effect
• Note: mana recovery rate is described as multiplicative, helping flasks and totem sustain.

Defensive / Utility Layers

• In weapon set 2:
  • Overwhelming Power / extra max power charges increases AoE/explosion size scaling
  • ES recharge + “faster start ES recharge” effects while Demon Form/shapeshifted
  • Blasphemy + Temp Chains as an always-on defensive aura (slows enemies and creates more reaction time)
• Armor-breaking alternative if skipping expensive passives:
  • use mark skills (not sniper mark) + Mark on Death setup

Skill Gem Highlights (what each is for)

• Spell Totem (weapon set 1):
  • Bonestorm
  • Ancestral Bond interaction implied via totem charge reservation
  • Urgent Totems recommended
  • Ricochet + Snake Pit synergy for clear/bossing near walls
  • Execute for finishing damage when applicable
  • Magnified Area to increase explosion AoE
• Mana Tempest: major damage/clear amplifier (more important on lower budget)
• Flame Wall: consumes infusions to generate power charges via the engine
• Powered by Verisium: provides the infusion
• Wolf Pack + Cast on Minion Death: automation trigger for Powered by Verisium
• Blasphemy curse package:
  • Temp Chains
• Optional bossing supports:
  • Elemental Weakness + Arbore Hex / Abiding Hex-style behavior for power charge consumption logic
  • Frost Bomb for elemental exposure

Key Tree/Node Priorities

• Ancestral Bond and other totem/crit/AoE interactions
• A mandatory “totem feel” wheel:
  • strong allocation in totem placement speed / placement range
  • the guide states the build shouldn’t be played without these, or it feels clunky
• Especially important nodes mentioned:
  • Fusion of Power / Infusion of Power (power charge engine)
  • Controlled Metamorphosis setup that “saves points”
  • Cut to the Bone if affordable/reaching it (otherwise use the cheaper armor-break alternative)

Gear Checklist (what to look for)

Essential weapon traits (staff for Bonestorm)

Priorities:

• Spell damage
• Cast speed
• + to spell skills
• Chance to fire 2 additional projectiles (ideal route to reach 100% with correct totals)
• +1 (optimal)
• Staff damage “type” note:
  • base staff type can vary, but you must use the correct damage modifiers, since Bonestorm functions like a multi-damage type in practice.

Infernalist defensive/sustain pieces

• Rise of the Phoenix
  • ideally corrupted for extra low-life regen, but baseline is usable

Scepter (weapon set 2)

Primary needs:

• Enough Spirit to run the setup (video target: about 176 Spirit)
• Mana regeneration rate
• Some Strength to manage life/max-life mismatch between weapon sets
  • or solve via a single skill point if lacking

Belts / low-life enabling

• Coward’s Legacy with the correct corruption:
  • must still count as low life at the threshold
  • remove/alter the “regen max life per second while on low life” line as described

Other setup pieces

• Snake Pit (ideally corrupted for ricochet interaction; budget is normal)
• Rings / gloves / boots:
  • mostly ES/res and standard defensive stats
• Cursor/cowboy details:
  • resistance and ES/movespeed are mentioned as normal

Budget Strategy (how to downgrade without killing the build)

Core idea:

• Reduce Spirit requirements and remove expensive components.

Budget path described:

• Don’t need charge regulation (or full Spirit for 3 totems).
• Aim for only 2 totems for mapping.

Budget substitutions:

• Remove Spirit from gear and compensate only via setup requirements
• Use a cheaper scepter alternative involving Skeletal Warriors (so you can replace Wolf Pack)
• Add Hulky Minions to make sacrifice targets large enough for Minion Pack detonations

Affordability references:

• Some pieces described around ~1 ex / a few ex
• Staff craft described as “under 1 div” for a sufficient version (exact market numbers vary)

Demonstration/Testing Notes (what happened in maps)

• Mapping showcase on Wayward Isle:
  • Demon Form active
  • power-charge generation working
  • two totems (budget style)
• Results:
  • solid clear for budget mapping (including “6-mod” content)
  • noted risk: enemies like “spore spirits” can make things tankier, but the build still handles it
• Bossing:
  • described as the build’s main strength
  • performs adequately on low-to-mid investment
