Arknights Endfield: Tangtang Banner Guide

Arknights Endfield opens its first RE-Factor Headhunting on 2026-10-29, putting the 6★ operator Tangtang on rate-up with a hard 120-pull guarantee. The paired weapon banner, Tender Sprig Issue, raises the odds for the 6★ handcannon Brigand's Calling over the same window.

Both banners close on 2026-11-19 at 11:59 server time, so there is a three-week runway to plan around. For a full picture of what else is running, see our Arknights Endfield news hub.

Times follow server time as listed in official materials. Asia runs on UTC+8, while Americas and Europe are grouped at UTC-5, which means the two regions do not flip over at the same moment. If you play across accounts, set a reminder for the earlier of your two reset points.

How the Tangtang Guarantee Works

The 120-pull guarantee is the part worth reading twice. You are guaranteed the rate-up 6★ Tangtang within your first 120 headhunting attempts on this banner.

That guarantee triggers only once across all [Ancestral Spring Flows Anew] RE-Factor Headhunting banners. Pulls you bank toward it carry over to future banners in the same family, so a partial count is not wasted if you stop early.

Base 6★ rates and the soft-pity curve are not stated in official materials. Treat any specific percentage circulating outside the in-game details screen as unverified.

Should You Pull for Tangtang?

The honest answer depends on your current roster and your tolerance for a long commitment. A 120-pull ceiling is generous by gacha standards, but it is still a ceiling, not a discount.

F2P players: count your pulls before the banner opens. If you cannot realistically reach a meaningful milestone, the carryover rule means partial progress is not lost — but you also get nothing immediate. Skipping is a legitimate choice.

Low-spend players: the milestone rewards below change the math. Thirty pulls effectively becomes forty, which is the cheapest meaningful stopping point on this banner.

Optimal spenders: if you intend to commit, commit early enough to use the free 10-pulls at 30, 60, and 90 attempts. Those bonuses only trigger once across the banner family, so there is no benefit to hoarding them for a later run.

Tangtang's kit, role, and team fit are not stated in official materials. We will avoid guessing at her placement in the meta until the in-game details are live.

Tender Sprig Issue: Weapon Banner Rules

The weapon side has two separate guarantees, and they behave differently.

• 6★ weapon guarantee: if no 6★ weapon appears in three consecutive issues, the fourth issue guarantees one. This applies only to [Tender Sprig Issue] RE-Factor Issue #1 and does not carry over to other issue banners, including future Tender Sprig runs.
• Rate-up guarantee: if no rate-up 6★ weapon appears in the first seven issues, the eighth guarantees one. This one triggers once across all Tender Sprig banners and does carry over.

That asymmetry matters. The generic 6★ safety net resets with this banner, while the rate-up safety net persists. If you are chasing Brigand's Calling specifically, only the second counter is portable.

Events and Rewards

Headhunting rewards

• Urgent Recruitment: at 30, 60, and 90 attempts you receive 10 bonus pulls each — one free 10× at every milestone. Triggers once across the banner family; unused attempts carry over.
• Token Tribute: every 240 attempts across all [Ancestral Spring Flows Anew] banners grants Tangtang's Token ×1. Attempts carry over.

Issue rewards

Reaching set attempt counts on the weapon banner yields Arms OC: Tender Sprig or Brigand's Calling (Handcannon) in alternating order. Accumulated attempts carry over to future Tender Sprig banners.

Exact thresholds for the issue rewards are not stated in official materials — check the in-game banner page for the full ladder.

What to Do Now

1. Confirm you have cleared [Chapter I Process I: Break the Siege]; without it, neither banner is accessible.
2. Log your current pull count and currency before 2026-10-29 so you know your realistic ceiling.
3. Decide in advance whether you are stopping at 30, 60, 90, or 120 — the milestone structure rewards a plan.
4. If you are only after the handcannon, remember the 6★ safety net does not carry past this issue.

The Takeaway

Tangtang arrives with one of the cleaner guarantee structures in the genre: a 120-pull ceiling, portable progress, and free 10-pulls at three milestones. The weapon banner is less forgiving, since its generic 6★ guarantee resets with this issue.

Plan your stopping point before 2026-10-29, and treat any rate figures you see outside the game client as unconfirmed.
