Which Weapon Supply Should You Choose in Arknights: Endfield

In Arknights: Endfield, the game is shockingly generous early on and just starts throwing free weapon selectors at you like it's trying to buy your loyalty. You get one after 40 Headhunts, another free 6★ weapon box at Level 45, and on top of that, the Protocol Pass hands you yet another selector with three very specific weapons inside. Sounds great, right? Until you realize that picking the wrong one feels way worse than missing a pull.

This guide explains how each selectable weapon effects, which characters benefit the most, and how to choose efficiently using only the information.The goal is simple: fewer regrets, fewer wasted boxes, and no staring at your inventory wondering who this weapon was even for.

Level 45 Weapon Box

The level 45 selector is best treated as a roster gap-filler, not as a “pick this every time” reward. Some of the available 6-star weapons are broadly useful, but none are so dominant that they completely override character compatibility. That means the most practical approach is to match the selector to the character you already use most often, or to the weapon slot your team still struggles to fill.

A useful way to think about the level 45 box is:

• Pick a weapon with good standalone performance if your account is still early and you need immediate combat value.
• Pick around a main carry or favorite character if you already know who you are investing in.
• Avoid duplicating value with a weapon category you expect to cover through other selectors or supply pulls.

Instead of locking players into a rigid overall ranking, it is safer to separate these weapons into practical use cases:

Weapon	Buff	Function
JET	Main attribute bonus Attack as a secondary stat Increased Arts damage after casting a skill or combo skill	This weapon performs well on elemental damage dealers, especially characters whose kits revolve around Arts damage. Characters who deal mostly physical damage gain little from the third effect, making JET only an “okay” option for them. Overall, JET is a universally usable polearm, but it currently shines on only a limited number of characters.
White Knight Nova	Main attribute bonus Arts Intensity as a secondary stat	Increased Arts damage and additional Arts Intensity after applying Combustion or Electrification While Arts Intensity can technically benefit physical effects, the third effect requires elemental application. As a result, physical characters cannot fully utilize this weapon. It can be serviceable on some Arts-oriented characters, but several of those characters already have better or free alternatives, making White Knight Nova a situational choice rather than a priority pick.
Detonation Unit	Main attribute bonus Arts Intensity A debuff that causes enemies to take increased damage after an Arts Burst (two identical inflictions in a row)	Detonation Unit remains one of the safer selections when you want something broadly useful rather than narrowly tailored. It works well as a stable account-strengthening pick, especially for players who want a weapon that contributes immediately without needing an overly specific setup. This is still one of the most reasonable choices when you do not have a very clear character-targeted plan.
Wedge	Main attribute bonus Critical Rate Increased Arts damage when casting skills and triggering Arts reactions	J.E.T and Wedge can both be strong choices when they are going to a character that can actually exploit their profile well. They become more appealing when your roster is already somewhat defined and you are no longer choosing purely for universal value. In those cases, matchup and user fit matter more than abstract ranking.
Exemplar	Main attribute bonus Attack Increased Physical damage when skills or ultimates hit enemies	This weapon is specifically valuable for physical damage dealers, especially those used as main DPS units. On such characters, Exemplar can perform very well. On non-physical characters, the third effect is effectively wasted, reducing the weapon's value significantly.

So for most players, the best summary is not “always pick the top-ranked weapon,” but rather:

• choose Detonation Unit if you want a reliable and generally safe value pick;
• choose J.E.T or Wedge if they clearly match the character you are building;
• leave White Knight Nova and Exemplar for more specific roster cases.

Max stacks for effects of the same name: 2. Duration of each stack is counted separately. Effect only triggers once every 0.1s.

Opus Edge Figure

Type: Arts Unit Rarity: ★★★★★★

ATK +7.0%. When the wielder's battle skill applies Nature Infliction, other operators in the team gain Arts DMG Dealt +5.0% for 15s. For every enemy suffering from Nature Infliction applied by the said battle skill, other operators in the team gain bonus Arts DMG Dealt +2.0%, up to a max of +6.0%. Effects of the same name cannot stack.

Navigator

Type: Handcannon Rarity: ★★★★★★

Critical Rate +5.6%. When Solidification or Corrosion is applied to enemies, the wielder gains Cryo DMG Dealt and Nature DMG Dealt +5.6%, and Critical Rate +3.2% for 15s. If this effect is triggered by the wielder, double the increase gained. Effects of the same name cannot stack.

Glorious Memory

Home Longing

Type: Handcannon Rarity: ★★★★★★

Effect:

ATK +19.6%. For 20.00s after the wielder casts a combo skill, the wielder's next battle skill gains Cryo and Nature DMG Dealt +22.4%. Max stacks for effects of the same name: 2.00. Duration of each stack is counted separately.

Recommendation

Decide who you actually want to build first, and only then claim the weapon that matches that character.

This is exactly where Battle Pass weapon boxes shine. You don't need to open them the moment you get them—hold onto them and use them later, once you're certain which character you truly need the weapon for. This becomes especially important when we start talking about the free weapon selector boxes, because a weapon might look great on Yvonne on paper. However, if you already plan to obtain Yvonne's Battle Pass weapon, then picking another weapon for her from a selector is simply wasted value. In that situation, you're much better off choosing a different weapon that fills a real gap in your roster.

 

New Horizons

Name	Effect
Oblivion	Critical Rate +14%. When the wielder casts an ultimate, the wielder gains Arts DMG Dealt +67.2% for 15.00s. When the wielder casts a combo skill, the wielder gains Arts DMG Dealt +33.6% for 15.00s. The two effects apply separately and do not stack with themselves.
Sundered Prince	When the wielder performs a Final Strike on the enemy, the wielder gains ATK +28% for 8.00s. If the wielder is also the controlled operator, double the ATK increase gained and buff the Final Strike so that it deals Stagger +33.6% to the enemy. Effects of the same name cannot stack.
Thermite Cutter	ATK +28%. After the wielder's skill recovers SP or grants a Link state, the entire team gains ATK +14% for 20.00s. Max stacks for effects of the same name: 2.00. Duration of each stack is counted separately.
Former Finery	Treatment Efficiency +28%. After a Protect icon.pngProtected operator takes DMG, the wielder restores the said operator's HP by [235.2 + Will×1.96]. Effect only triggers once every 15.00s.
Valiant	ATK +28%. After the wielder applies Physical Statuses, the wielder also deals another hit of Physical DMG equal to 336% of the wielder's ATK.

Best Choice: Thermite Cutter

Thermite Cutter offers the highest overall value because it combines unconditional ATK +28% with a long-duration, stackable team ATK buff that triggers naturally through SP recovery or Link mechanics. It has high uptime, minimal conditions, and works in nearly any team composition.

Compared to other options that rely on specific damage types or niche mechanics, Thermite Cutter provides consistent personal strength plus real teamwide impact, making it the safest and most universal recommendation.

 

Conclusion

The free weapon selectors in Arknights: Endfield are designed to be flexible rather than overpowered. None of the options are strictly wrong, but efficiency comes from matching weapons to characters you actively use and planning around which signature weapons you can realistically obtain.

Choosing with roster needs in mind will always outperform chasing theoretical best-in-slot options.

And yes, free weapons are free for a reason. They're solid, they're serviceable—but if you want real damage and numbers that make bosses disappear a little too fast… well, that's where wallets enter the chat. Top up Origeometry with LDShop and grab those premium pulls without the pain. Free boxes are for surviving—LDShop is for thriving.
