Gunlance Guide

Gunlance combines severing lance attacks, a strong shield, and fixed-damage shelling. Shell type and level define a separate damage subsystem, so a skill can be essential to one Gunlance route and irrelevant to another.

Scope and Weapon Model

This article assumes final-patch Iceborne. Gunlance's displayed Attack multiplier is 2.3, so 690 displayed Attack represents 300 true raw. It is a heavy clutch weapon. The official manual: Hunter's Notes owns basic controls; this reference separates melee, shelling, stakes, guard, and skill scaling.

Shelling Formula and Types

Ordinary shell damage contains fixed raw plus a small fire component determined by shell type and shell level. The fixed component ignores raw and elemental hitzones, cannot crit, does not use weapon Attack, and is not multiplied by weapon sharpness. At yellow sharpness or lower, shell damage instead receives a 0.85x penalty; at red, shelling is unavailable. Each shell also consumes sharpness.

Shelling Formula and Types
Shell typeBase magazineFavored shell interactionCharged-shell fixed multiplier
Normal5Full Burst uses the large magazine.1.60x
Long3Long reach and the largest charged-shell multiplier.2.35x
Wide2Strong individual shells and Wyvern's Fire.1.40x

Artillery raises eligible shelling, stake explosions, and Wyvern's Fire damage and reduces Wyvern's Fire cooldown at specified levels. Capacity Boost adds one shell, changing Full Burst totals and reload cycles. Attack, affinity, Critical Boost, element attack, and sharpness color above green do not raise the fixed component.

Melee and Shelling Routes

No one skill table describes all four models. The share of fixed shell damage versus direct melee damage must be stated before assigning offensive priorities.

Wyrmstake Blast

Iceborne's Wyrmstake Blast loads slinger ammunition into a stake that persists on the attached monster part. Gunlance fixed-damage attacks striking that stake trigger a second explosion. Its duration depends on the loaded ammunition and amount.

Wyrmstake Blast
TriggerWyrmstake Blast fixed multiplier
Ordinary shell1.00x
Charged shell3.00x
Full Burst1.65x per shell trigger
Wyvern's Fire3.00x per eligible trigger
Wyrmstake Cannon2.00x

Fixed damage from another player triggers only 0.25x of the normal Wyrmstake Blast value. The stake does not wound the monster part and does not turn its physical hitzone into a weak point.

Core Offensive Priority

Core Offensive Priority
PrioritySkill or systemMechanical reason
1 for shellingHighest practical shell levelShell level is a primary input to fixed damage and cannot be recovered through ordinary raw skills.
1 for shellingArtillery Lv 3 or Lv 5Directly raises the shell subsystem; Lv 5 requires Artillery Secret.
1 for Full BurstCapacity Boost Lv 1Adds another shell to the burst and changes reload economy.
1 for melee-heavy routesWeakness Exploit, affinity, Critical Boost, and sharpness supportScale thrusts, smashes, and sweeps but not fixed shell damage.
2FocusShortens charged shelling; little value when the selected route does not charge shells.
2Slinger CapacityCan increase the amount loaded into Wyrmstake Blast and therefore its duration.
3Clutch Claw Boost Lv 1Gunlance already wounds in one heavy attack; the skill adds slinger-ammunition drops.

Non-elemental Boost can strengthen eligible melee raw, but not shell fixed damage. Likewise, Partbreaker affects part damage while fixed shells already ignore the physical HZV; neither statement means direct monster-health damage is multiplied by Partbreaker.

Defensive and Utility Priority
