Disclaimer: Two prevalent methods existed for acquiring extra projectiles in this build during Necropolis. Both approaches, whether you chose the Rain of Splinters or the Thread of Hope variation, were roughly equivalent in efficiency. The decision came down to which option was more economical at your point in the league economy.
Introduction: The Explosive Arrow Ballista build received widespread attention across Necropolis 3.24. This guide covers the full build: mechanics, ascendancy, gear tables, and gem links, so you can follow it historically or adapt the framework to a current league-legal equivalent.
Ratings across five key categories on a 1-10 scale. Higher is better.
| Durability | Damage | Playstyle | Gearing | Complexity |
|---|---|---|---|---|
| 9.5/10 | 9.5/10 | 7/10 | 7/10 | 5/10 |
Durability and damage both scored 9.5/10 in Necropolis. This build absorbed significant punishment while totems continued stacking fuses. Playstyle and gearing sat at 7/10, reflecting a moderate investment requirement and a play pattern that demanded consistent cursor work to maintain totem uptime. Complexity at 5/10 made it accessible to intermediate players with prior totem experience.
The core loop of the Explosive Arrow Ballista Champion is straightforward despite its reputation for math-heaviness. The primary objective was to affix as many explosive arrows (fuses) onto a target as possible before the detonation timer expired, leveraging the gem's "more damage" multiplier. Each Ballista totem applied fuses independently, so six totems running simultaneously compounded the fuse application rate dramatically.
While the build performed as a powerhouse in mapping and the endgame, it required a melee phase during leveling. Until level 28, players leveled using Shattering Steel or Splitting Steel. This phase felt cumbersome by design, and the power spike on switching to Explosive Arrow served as the payoff. Acquiring a Quill Rain early made the transition noticeably smoother.
In the endgame, the play pattern reduced to deploying six ballista totems while navigating maps. On bosses, players activated Frenzy to generate charges, applied Flammability via Hextouch, and kept endurance charges rolling through Enduring Cry.
📌 Common Mistake: Many players placed one or two totems instead of all six at boss entry, then found damage underwhelming. Explosive Arrow's fuse-stacking damage is not linear: six totems applying fuses simultaneously versus two is roughly a 3x difference in time-to-cap, which translates directly to a 3x shorter kill window on tanky map bosses.
Elemental Equilibrium Activation: Elemental Equilibrium required a single roll of Lightning or Cold damage to attacks on gear or jewels. Any "Fire Damage to Attacks" affix would break it. Explosive Arrow's fire hits would then buff enemy fire resistance rather than reducing it, gutting overall damage without any visible feedback in the combat log.
Fuses Math: Explosive Arrow's explosion damage and ignite scaled with the number of fuses embedded at detonation. To reach the damage cap:
An optimized Path of Building (PoB) for the Explosive Arrow Ballista Champion is available here. Every WowCarry build guide uses the community fork of Path of Building, which receives more frequent updates and has broader feature coverage than the original.
✏️ Tip: In 3.28 Mirage, Awakened Support Gems are legacy items that no longer drop in-league. Exceptional Support Gems replace them. If you are running this build framework in a current league, substitute Exceptional Elemental Damage with Attacks for the Awakened version listed below. The gem socket layout and support priorities are otherwise identical.
Gem Links — Main 6-Link (Explosive Arrow):
Frenzy: Applied curses and generated Frenzy Charges while totems handled heavier foes.
Auras: Early in the league, Defiance Banner could not always be run due to the helmet implicit cost. Priority order:
Utility: Arcanist Brand linked to Flame Surge debuffed enemies. Enduring Cry on the left mouse button maintained Endurance Charge generation. Lifetap Support on both skills triggered them through life expenditure instead of mana.
Dash served as the primary movement skill; Flame Dash and Blink Arrow are valid alternatives. Vaal Molten Shell should be activated entering dangerous encounters or during invulnerability windows.
Ascendancy Choices for the Explosive Arrow Ballista Champion
Dealing with the Bandits
Kill all Bandits. The two passive skill points from Eramir outweigh the stat bonuses offered by Oak, Alira, or Kraityn for this build's passive tree configuration.
Pantheon Choices
Upgrading Pantheons
To upgrade a Pantheon power, place a Divine Vessel in the Map Device alongside the Map containing the required boss. After defeating that boss, the filled Vessel can be taken to Sin in Oriath to apply the upgrade.
⚠️ Warning: Soul of Abberath requires a specific Map boss to upgrade. Do not skip this step before progressing to red maps. Burning ground in T15+ maps could down this build during totem placement if the Abberath upgrade was absent, since the play pattern involved several seconds of stationary repositioning.

Jewels and Flasks:
The Explosive Arrow Ballista Champion was one of Necropolis 3.24's strongest all-round league-starters: exceptional durability through permanent Fortify, a damage ceiling reached early, and a clear progression from Quill Rain to a crafted endgame bow. The leveling phase as a melee build was the main concession, and most players cleared it in a single session. To skip the painful campaign phase entirely, Browse PoE build carry options and get straight to mapping.
Last reviewed 2026-06-18 against Patch 3.28 Mirage — Maintained by WowCarry's PoE team.
The core mechanics are unchanged: fuse stacking via Ballista Totems, ignite scaling, and permanent Fortify from the Champion ascendancy all function identically in 3.28. The main adaptation is swapping Awakened Support Gems for Exceptional Support Gems, which replaced them in the current league. Gem link order and priorities are otherwise the same, and the build clears red maps and endgame bosses comfortably.
Explosive Arrow caps at 20 fuses (the initial hit plus 19 stacks). At a 1.2-second duration, you need roughly 15.8 fuses per second from your totems. Six totems each attacking at 2.64 attacks per second covers that threshold. Duration-increasing cluster jewels or passives let you hit the cap at lower attack-speed breakpoints, which is worth considering when your Thicket Bow lacks sufficient attack speed rolls.
The most common culprit is a "Fire Damage to Attacks" affix on gear or jewels. This breaks Elemental Equilibrium: instead of lowering enemy fire resistance, your hits raise it, cutting damage substantially. Check every affix on rings, gloves, and jewels. The build requires a single roll of Lightning or Cold damage to attacks as the EE trigger, and zero fire damage to attacks affixes.
Switch at level 28 when Explosive Arrow becomes available, and pick up Quill Rain from a vendor or trade as soon as you can afford it. The transition is rough for about ten levels until attack speed supports 2-plus totems firing continuously. By Act 5-6 with Quill Rain equipped and Ballista Totem Support linked, the build's mapping power overtakes the melee phase completely.
Dyadian Dawn doubled the ignite duration on shocked enemies. Since the primary damage vector was the sustained ignite from high-fuse explosions, a longer burn window directly multiplied total fire damage output over an encounter. A rare Stygian Vise with comparable stats costs significantly more than this unique during league start, so Dyadian Dawn was not practically replaceable at the same price point.
Both served the same role: generating additional arrow projectiles from each totem so fuses stacked faster and more reliably. Rain of Splinters required a corrupted jewel socket and offered more predictable projectile counts; Thread of Hope provided passive skill allocation flexibility at a higher currency cost. Buy whichever is cheaper on your league's trade site at the point you are ready to invest.
Worthy Foe's "enemies take 20% increased damage" modifier applies as an increased multiplier in the damage formula, not a separate "more" multiplier, despite the tooltip language in 3.24. In practice it was still a meaningful damage boost, and eliminating the accuracy requirement freed passive skill points and gear affixes from the accuracy budget.
In Necropolis 3.24, the optimized late-game version cleared all pinnacle bosses including Uber Elder and Shaper. Uber Exarch and Eater required the crafted Thicket Bow setup and full Pantheon upgrades including Brine King for freeze immunity. Uber Sirus was the most accessible of the Uber fights due to this build's combination of high physical mitigation through Determination and the Champion's innate Fortify stack.
