Version 1.1's calendar for Endfield is the first time in a while I've felt like I can plan my weeks without guessing. If you're juggling work, raids, and the usual "just one more run" problem, having the dates spelled out helps a ton. It also makes it easier to decide whether you're saving for a specific Operator or just trying to keep your account moving, especially if you've ever looked into Arknights endfield boosting as a way to stay on pace without living in-game.

Phase One: Tangtang and the early grind

First up, Tangtang's banner runs from the 12th through the 29th, which is a healthy stretch if you're not the type to pull day one. The 12th is busy, though. New sign-in rewards drop, plus fresh combat drills, and those drills are worth more than people think. You'll quickly notice they're a low-stress way to try weird team ideas before you sink sanity into real farming. The Quietly Flows the Spring event also starts on the 12th, and since it overlaps into the next banner window, you can take it at a normal pace instead of speedrunning the shop in a weekend.

Sanity discounts and what to farm

During this first half, the schedule also calls out Exploration Day and a sanity discount period. That discount is where the patch basically pays you back for being patient. If you're low on upgrade mats, this is the moment to stockpile, not when you're panicking at 2 a.m. because you pulled someone new and can't build them. A lot of players burn their sanity on whatever's "fun" that day. Try flipping it: use discounted sanity for boring but necessary mats, and keep your normal-cost runs for story progress or experimenting.

Phase Two: Rossi arrives and the vibe changes

On the 29th, Tangtang rotates out and Rossi takes over, and you can already tell that's when many people plan to go all-in. The second half isn't just a banner swap, either. Delver of the Cryptic shows up to keep the combat side ticking, but the oddball highlight is Cleanse and Rinse. It's basically a power-washing mini event inside Endfield, and yeah, it sounds silly. After a string of tight fights and timed clears, that kind of "turn your brain off" content is a welcome reset. There's also another sanity discount during Rossi's run, then a survival training event to see who actually built their roster instead of just chasing the newest face.

Permanent upgrades you'll feel every day

Beyond the limited events, 1.1 adds changes that matter long after banners end. The general Etchspace Salvage upgrade arrives alongside Tangtang's phase and should make resource handling less fiddly, especially if you're constantly capped or constantly broke with no in-between. Two Umbral Monument updates are spread across the patch as well, so check in even if you're skipping both banners; slow account power comes from systems like that. If you're trying to keep pulls disciplined, use the calendar like a budget, lean hard on the sanity discounts, and consider whether buy Arknights endfield boosting makes sense for you when real life gets hectic but you still want to stay caught up.
