Genshin Impact Resin Guide

The One-Paragraph Answer

Original Resin regenerates 1 point every 8 minutes, caps at 200, and refills from empty in 26 hours 40 minutes. You naturally bank 180 per day. That single sentence drives almost every farming decision in Genshin Impact — everything below is detail, caveat, and how to stop wasting it.

Why Resin Is the Real Currency

Mora, talent books, weapon ore, artifact rolls — every progression system in the game eventually funnels through Resin. Domains cost 20, world bosses 40 (60 at higher world levels), weekly bosses 30-60, and the 5-star artifact grinder (the highest-value sink) 40 per run. A day's natural income covers four to nine runs depending on what you are hitting, which is why planning beats grinding: the resin calculator tells you exactly when the next run unlocks.

The Cap and the Overnight Problem

At 200, regeneration stops dead — no overflow pool, no banking. Sleep eight hours at 152 Resin and you lose nothing; sleep at 200 and you burn four hours of regen. Two fixes exist. The lazy one: spend down below the cap before logging off. The better one: craft Condensed Resin (40 Resin + 100 Mora each, five held). Condensed Resin banks the value without the cap problem, and spending it on ley lines and domains doubles the loot per claim.

Primogem Refills: The Full Ladder

Six refills per day, 60 Resin each, at 50 / 60 / 80 / 100 / 150 / 200 Primogems. The first refill costs 0.83 Primogems per Resin — comparable to good event value. The sixth costs 3.33, which is worse than almost anything else you could buy with those Primogems, including wishes themselves. If you refill at all, treat one or two as the ceiling; past that you are paying a convenience tax the game does not need you to pay.

Resin Feeds Your Adventure Rank

Every point of Resin spent also grants 5 Adventure EXP (20 Resin = 100 EXP) — the only renewable AR source. If you are chasing AR45 for the guaranteed 5-star artifact domain, the AR calculator converts your daily Resin into a real day count: 207,800 EXP to AR45 is about 231 days on Resin alone, but half that once quests, chests and events are counted.
