Weapons
Arknights: Endfield weapon guide covering supply pools, essence upgrades and which weapon banners are worth pulling for each operator.
Introduction
Weapons are the top of the investment curve in Arknights: Endfield. Five weapon types exist, Sword, Greatsword, Polearm, Handcannon and Arts Unit, and the type decides which supply pool an operator draws from, so weapon planning is inseparable from roster planning. The guide here covers how supply pools rotate, how weapon essence converts duplicate gear into upgrade value, and which supply banners are worth pulling versus which ones should be skipped in favour of operator pulls. The guide is organised around that dependency: decide which operator you are building first, identify the weapon type and supply pool that serves them, and only then decide whether a supply pull or a craftable upgrade is the right next step.
Weapon Supply Cheat Sheet
| Type | Who Uses It | Supply Priority |
|---|---|---|
| Sword | Fast melee carries and duelists | High if you main a sword carry |
| Greatsword | Heavy single-target damage dealers | High for boss-focused accounts |
| Polearm | Front-line anchors and stagger sources | Medium, role-dependent |
| Handcannon | Ranged pressure on staggered targets | Medium, needs a stagger partner |
| Arts Unit | Casters scaling off Arts damage | High if you run an Arts carry |

Core Mechanics
Weapon upgrades come from the supply system. Each weapon type has its own pool, and operators can only use weapons matching their type, which means a supply pull is only valuable if you already own an operator who can equip the result. Weapon essence tools convert duplicate or unwanted weapons into upgrade value instead of leaving them idle. Weapon banners also rotate on a separate schedule from operator banners, so a carry you have just built can end up waiting on a weapon rotation that has already passed. Because weapon types are locked to operators, a supply pull is only as valuable as your roster is wide. Converting unwanted drops into essence recovers some value from failed pulls, but it does not turn them into power, which is why supply spending belongs after roster decisions rather than before them.
Advantages
Prioritising weapons correctly is where a build crosses from functional to strong, because the weapon multiplier sits on top of every skill, gear and artifact bonus already invested in an operator. Understanding the pool structure also prevents the most common waste: pulling supply banners for weapon types no operator on your roster can equip, which converts currency into essence rather than into power. Getting the weapon step right is what makes a finished build feel finished. The weapon multiplier sits on top of every skill, gear and artifact bonus already invested, so the same operator can feel two tiers apart depending on whether the weapon step was completed.
Challenges
Weapon investment is the least forgiving upgrade path. Banners rotate, so a weapon worth pulling today can become unavailable before you finish building the operator it suits, and refinement materials are scarce enough that spreading them across several weapons leaves all of them underpowered. Signature weapons also carry a real opportunity cost, because the same currency spent on a weapon is currency not spent on the operator banners that widen your roster. Weapon investment also carries the highest sunk cost of any upgrade path. Because banners rotate, a weapon worth pulling today can become unavailable before the operator it suits is finished, and refinement materials are scarce enough that a wrong early choice is difficult to recover from.

Quick Tips
Match the weapon type to your roster before you spend anything. Weapon types are locked to operators, so a supply pull is only valuable when you already own someone who can equip the result, which makes roster planning the correct first step in every weapon decision. Confirm you own an operator who can equip a weapon type before pulling on its supply banner, otherwise the currency converts into essence rather than into power.
Upgrade a craftable weapon before chasing a signature. Craftable and easily obtained weapons carry early and mid game comfortably, and keeping your operator functional while you bank supply currency is strictly better than leaving them underpowered until a signature pull lands. Keep a craftable weapon upgraded on any operator you are still deciding about, so they remain usable while you save for a signature pull that may never arrive.
Refine one weapon at a time rather than spreading materials. Refinement materials are scarce enough that splitting them across several weapons leaves all of them underpowered, while concentrating them on the weapon your main carry actually uses produces a visible jump in damage. Concentrate refinement materials on your main carry's weapon rather than spreading them, since scarce materials split across several weapons leave all of them underpowered.
