Genshin Impact Boss Materials: World and Weekly Bosses

Genshin Impact boss materials come from two kinds of boss. World bosses drop the ascension materials that raise a character's level cap: they cost 40 Original Resin a time and can be fought as often as you like. Weekly bosses drop the talent materials needed from talent level 7 up, and each one pays out only once a week.

World bosses and Genshin Impact ascension materials

World bosses stand in the open world: the Hypostases, the Regisvines, the Oceanid, and new ones with every region. Each drops its own material plus gemstones of its element, and every character needs the material of exactly one of them. The Cryo Regisvine feeds a group of Cryo characters, the Electro Hypostasis a group of Electro characters, and newer characters usually need a boss from their own region.

What to know before you farm one:

• The fight is free. Collecting the reward afterward costs 40 Original Resin.
• There is no daily or weekly limit. The boss comes back a few minutes after you leave the area, so teleport away, wait and return.
• A kill gives one to three boss materials, and more of them the higher your World Level is.

A character needs 46 of them to pass every ascension phase. The first phase asks for none, the next ones ask for 2, 4, 8 and 12, and the last phase alone asks for 20. That is somewhere around twenty kills for one character, which means several days of resin.

The gemstones come in four sizes. Three of a smaller size combine into one of the next size at the crafting bench, so the small ones are never wasted.

Weekly bosses: talent materials, the limit and the discount

A weekly boss in Genshin is a story boss you can fight again: Stormterror, Andrius, Childe, Azhdaha and the ones that later regions add. Most of them wait in a Trounce Domain, and each opens after you beat it in the quest where it first appears.

They work differently from world bosses:

• Each weekly boss gives its reward once a week. The week resets on Monday at 04:00 server time.
• The first three rewards you claim in a week cost 30 Original Resin each. Any after that cost 60.
• Each boss has three different talent materials and drops them at random. A character needs one particular material from one particular boss.

Talent levels 7, 8, 9 and 10 need 1, 1, 2 and 2 of that material. That is 6 for one talent and 18 if you want all three talents at the top.

Because the drop is random, you will often collect the wrong kind. This is what Dream Solvent is for. Weekly bosses sometimes drop it, and at the crafting bench one solvent turns one talent material into another from the same boss. Keep every solvent you get.

Weekly bosses are also the source of billets you can repeat every week. Billets are the rare items a blacksmith needs to forge four-star weapons, and that alone is a reason to claim three rewards a week, even when no talent is waiting.

How to see which boss a character needs

Open the character, go to the ascension preview or to a talent, and select the material: the game shows where it comes from. The Adventurer Handbook also lists the bosses with what they drop and can mark the way to them.

Do this before you spend resin. Two characters of the same element do not always share a boss.

Planning your week around both

Original Resin comes back at one point every 8 minutes, which is 180 a day. That budget has to cover bosses, talent books, artifacts and everything else, so a plan helps.

1. Early in the week, claim the three weekly bosses your current characters need, at 30 resin each. That is 90 resin, half a day.
2. If you have more than three weekly bosses unlocked, choose by need. A fourth at 60 resin is worth it only when you need that exact material now.
3. Farm a world boss when a character is close to an ascension, and stop when you have what the next phase asks for.
4. Spend the rest on what is short: talent books, weapon materials or artifacts.

The weekday calendar players talk about belongs to talent books and weapon materials. Their domains open on fixed days of the week, and all of them open on Sunday. Bosses follow no calendar: a world boss is there any day, and a weekly boss any day you have not claimed it that week.

Check your resin before a boss fight. If you can't pay for the reward, the kill gives you nothing.

Both kinds of boss can be fought in co-op. Each player pays their own resin and gets their own drops, so a friend can help you through a boss that is too hard alone. The co-op guide explains how to join a world, and daily commissions and resin covers the rest of the daily budget.

Mistakes that slow a character down

• Skipping weekly bosses for a few weeks. Their materials are limited by time, and six per talent can't be caught up later.
• Pushing every character through the last ascension phase. It costs 20 boss materials, nearly as many as all the earlier phases together.
• Starting to farm only after you get a character. If you know who you are saving for, collect that boss's materials ahead of time.
• Farming a boss by its element. Check the character's screen first: the element is a hint, not a rule.

Frequent questions

How many boss materials does one character need?

46 world boss materials for all ascension phases, and 6 weekly boss materials for each talent you raise to level 10. The last ascension phase takes 20 of the 46.

When do weekly bosses reset?

On Monday at 04:00 server time. From then on, every weekly boss can give its reward once more, and the three discounted claims are available again.

Can I turn one weekly boss material into another?

Yes, with a Dream Solvent at the crafting bench, but only into another material of the same boss. It can't change a material from one boss into a material from a different boss.

Do weekly bosses drop ascension materials?

No. They drop talent materials, along with gemstones, artifacts and sometimes a billet or a Dream Solvent. The material a character needs for ascension comes from a world boss.

Resin does the farming, Genesis Crystals do the wishing

Boss materials can't be bought. They take resin and time, which is why a weekly plan pays off. Genesis Crystals serve a different purpose: they convert into Primogems for wishes, so the character you collected materials for can actually join your account.

When you want to top up, you can get Genshin Impact Genesis Crystals on Mas4Games, loaded by UID and server. You give only your UID and server, never a password, and the help center has live support for questions about an order.
