The Forge spear builds that matter: Ore mixes, traits, and runes

Spears arrived in The Forge with the Winter Update as a late-game, level‑70 weapon line tied to Frostspire Expanse (Island 3). They sit between straight swords and colossal blades: longer reach than most melee options, but without the extreme weight and wind‑up of heavy weapons. That makes recipe efficiency even more important — a bad roll wastes rare volcanic ores on a weapon that lives or dies on consistent hit uptime.


How spear crafting works in The Forge

Spears are not a separate blueprint you pick from a menu. Weapon type is decided by two things: the total ore count you drop into the crucible and the game’s internal RNG table for that ore count.

The key breakpoint for spears is the ore total.

Ore count in crucible Primary possible weapon classes Notes for spears
4–8 Daggers, Straight Swords, small variants Too low for reliable spear rolls.
16 Spear, Trident, other medium‑heavy weapons Peak spear chance (around 69% for a spear‑class weapon).
20+ Greatswords, Colossals, heavy weapons Spears become much less likely.

With exactly 16 ores in the crucible, the forge gives roughly a 69 percent chance to land a spear. That is the highest known spear probability and the baseline for most serious builds. Adding more ores pushes you toward heavier weapon classes; using fewer drops your spear odds while also shrinking your stat budget.

Tip: if you are specifically chasing a spear instead of “any good roll,” treat 16 ores as non‑negotiable and adjust only which ores you use, not how many.

All spear variants and base stats

Spears come in four flavors: the basic Spear, the Trident, the Angelic Spear, and the Demonic Spear. Only two of them have published baseline stats so far, but they capture the design of the class.

Spear type Damage Attack speed DPS Range Base price
Angelic Spear 9.75 0.41 s 23.78 11 studs $120
Demonic Spear 9 0.56 s 16.07 11 studs $120

Both premium spear variants share the same reach and price, but their tuning is different. The Angelic Spear is faster and ends up with noticeably higher raw DPS on paper, while the Demonic Spear hits slightly harder per swing but does fewer attacks over time. When you add ore traits and runes on top, the faster attack profile tends to scale better, especially with on‑hit effects like explosions, burns, and lifesteal.


Why Magmaite, Eye Ore, and Fireite dominate spear builds

Most late‑game weapons in The Forge lean on the same handful of volcanic ores because they do more than raise the multiplier. For spears, three ores stand out:

  • Magmaite adds a chance for an area‑of‑effect explosion on hit.
  • Fireite adds a chance to inflict burn damage over time.
  • Eye Ore increases weapon damage at the cost of some maximum health.

These are not flavor bonuses. They create a specific play pattern that fits how spears work.

Spears naturally poke at groups from 11 studs away, often clipping multiple enemies that stack in narrow corridors or around bosses. A Magmaite explosion centered on one target can catch nearby mobs for 50 percent of the spear’s damage, effectively turning a single stab into a mini‑AoE nuke. Burn from Fireite ticks after the strike, cleaning up survivors without costing more animations.

Eye Ore is the risk piece. It shaves off a portion of your health to push your total weapon damage up, and that amplified damage also feeds into explosion and burn calculations. On something like a colossal sword, you might prefer safety; on a spear that can play at range and reposition quickly, sacrificing some HP in exchange for more damage per thrust is usually a good trade.

Note: trait‑bearing ores need to account for roughly 30 percent or more of your recipe to fully unlock their traits. With a 16‑ore spear build you can comfortably max three traits if you split the stack carefully.

Core 16‑ore spear recipe (Magmaite + Eye Ore + Fireite)

The most consistent high‑end spear builds all orbit the same core trio. The exact counts can shift based on your inventory and how aggressively you want to stack Eye Ore, but the structure stays similar.

A solid baseline layout looks like this:

  • 6× Magmaite
  • 5× Fireite
  • 5× Eye Ore

That hits the 16‑ore requirement for peak spear odds while also meeting the trait thresholds on all three ores. Magmaite, Fireite, and Eye Ore each contribute around a third of the total, ensuring you unlock:

  • The full explosion trait from Magmaite, dealing a percentage of weapon damage in a radius;
  • The full burn trait from Fireite, applying damage over time with a reliable proc chance;
  • a strong weapon‑damage bonus from Eye Ore in exchange for reduced health.

Because all three ores sit in a similar multiplier band, you avoid dragging your final damage multiplier down with low‑tier filler. The spear that drops out of this mixture hits well above its base DPS, then snowballs further once you upgrade and add runes.

If you are short on any one of the trio, the first lever to pull is Eye Ore. Reducing Eye Ore by one or two pieces softens the health penalty while still offering a noticeable damage bump. Avoid cutting Magmaite below the trait threshold; losing consistent explosions has a much larger impact on how the spear feels in dense fights.

Alternative spear recipes when rare ores are limited

Not every player will have a deep stock of volcanic ore when they first unlock Frostspire Expanse. You can still use the same logic with a slightly cheaper mix.

Two patterns work surprisingly well:

  • Explosive spear without Eye Ore – focus on Magmaite and Fireite, then fill the rest with high‑multiplier non‑trait ores you actually have.
  • Budget Eye Ore spear – use Eye Ore to get a damage gain and fill the remaining slots with one of Magmaite or Fireite plus solid mid‑tier ores.

For an explosion‑first build that avoids the health penalty, a simple spread like 8× Magmaite and 8× Fireite still gives double trait coverage as long as both ores remain comfortably above the 30 percent mark. You lose some top‑end power from skipping Eye Ore, but the spear becomes much safer to play and more forgiving if you are still learning enemy patterns.

For a damage‑centric budget spear, you can invert the idea and run something like 6× Eye Ore, 5× Magmaite, and 5× a non‑trait high‑multiplier ore such as Ruby or Rivalite. That keeps explosions in the mix while leaning harder into raw weapon damage and critical chance.

Tip: whichever direction you go, keep the total at 16 ores when the goal is “a spear now.” Pushing up toward 20+ ores is only worth it if you are intentionally targeting colossal weapons instead.

Best spear runes: Blast Chip and Drain Edge

Ore choices determine the core identity of the spear; runes decide how far you can stretch that identity. Across weapons, two runes stand out for sheer impact.

  • Blast Chip layers additional explosion‑style damage effects on hit. On a spear that already procs Magmaite explosions, the rune’s extra impact stacks into a barrage of overlapping bursts whenever you stab into a crowd.
  • Drain Edge adds lifesteal on hit. With the spear’s fast thrusts and sizeable AoE package, this translates into frequent, meaningful healing ticks, offsetting the health penalty from Eye Ore and smoothing out chip damage in long boss fights.

The synergy here is straightforward. Magmaite and Fireite push your outgoing DPS high enough that each individual hit — and each explosion — is worth healing from. Drain Edge turns that output into survivability. Meanwhile, Blast Chip increases the number of impactful events that can trigger both burn and lifesteal, since some on‑hit checks will fire multiple effects in a single animation.

If you are limited on rune slots or scrolls, prioritize getting Drain Edge onto any Eye Ore‑heavy spear first to stabilize your health bar, then add Blast Chip once your sustain feels comfortable.

When to chase Angelic and Demonic spears

Angelic and Demonic Spears sit on top of the spear line as named variants with fixed baselines. Their raw stats are close, but the tuning leans them in different directions:

  • Angelic Spear is the clear DPS option out of the box, thanks to a faster 0.41‑second swing and higher calculated damage per second.
  • Demonic Spear swings more slowly at 0.56 seconds per attack and lands slightly weaker DPS without traits or runes.

Once you forge them with a Magmaite–Fireite–Eye Ore mix and add the right runes, both become fully viable. The Angelic variant remains better suited for runes and traits that trigger on hit — every extra stab is another roll for explosion, burn, and lifesteal. The Demonic variant fits players who prefer reading individual attacks and trading fewer but chunkier hits, especially if they are pairing the spear with tankier armor sets rather than damage races or Eye Ore‑heavy builds.

Practically, it is not worth burning rerolls or ore stacks just to “force” one named spear over the other. Focus on nailing your 16‑ore recipe and rune setup; whichever high‑tier spear you land will carry comfortably through Frostspire Expanse content and beyond.


Spears in The Forge reward deliberate crafting more than almost any other weapon type. Getting the ore count wrong can push you into a completely different class of weapon, while a well‑tuned 16‑ore mix around Magmaite, Fireite, and Eye Ore turns a simple polearm into a screen‑clearing, self‑sustaining damage engine. Lock in that structure, layer Blast Chip and Drain Edge on top, and the only real bottleneck left is how quickly you can mine enough ore to keep rolling for better masterwork tiers.
