Ever wondered how to tell which artifact between two is better? Ever wanted an easy way to tell if you should fodder an old artifact for a new one? Just want to know how good your own artifacts are to brag to your friends? Ever wondered when to stop or continue to enhance an artifact? Well I’m going to try and make a concise and clear guide on how I choose to compare and roll artifacts for my characters on my account! ^-^
ps this guide will mostly focus on high investment main or sub dps artifacts and therefore will be mostly talking about crit stats ok thanks hf
*General Artifact rules*
– Main stat > substat > set bonus
– 5* artifacts start with 3 or 4, rolls and roll/upgrade for a total of 9 or 9 rolls.
maybe more stuff here with edits for clarity >->
Now, to answer the above questions, we need to first learn how to do two things:
A.) How to compare two artifacts of the same Set, Type, and Main Stat.
B.) How to judge the quality of an artifact in isolation
Okay, so first off, we can all probably agree that the most valuable substats for an artifact by far are both Critical Rate and Critical Damage, which ill abbreviate as crate and cdmg. Now, as a lot of you may know, all 5* artifacts can either start with 3 substats or 4 substats, and will either add a new substat (if the former, only on +4) or upgrade a previous substat (on +4, if the latter, then on +8/12/16/20.) When you roll a substat, the number that it adds isnt totally random, its chosen from a table of 4 potential values, randomly. For crate and cdmg, those numbers (from genshin wiki) can be seen here.
Top is crate, bottom is cdmg.
And the big kicker here: the crate rolls are actually exactly half of the values for cdmg, which means that you can compare two artifacts by… (crate * 2) + cdmg! And all you need to do is pick the artifact that has the higher score! This fact is actually true for all crit stats in the game, including circlets (31.1 crate or 62.2 cdmg) Also, from now on, I’ll be calling this number (2 * crate + cdmg) the “crit score” of an artifact. Here is an example!
a different gladiator flower
We can see that one artifact has 28% cdmg, and the other has 13.2% cdmg and 9.3% crit rate. 28% crit damage seems like a lot, so I’d say most people will be quick to gun for the first flower. But, if you use the formula, we can see that the second flower has a crit score of 31.8% (9.3 * 2 + 13.2) and the first flower only has a crit score of 28% (28 + 0 *2) and will actually contribute more crit to your overall build. I recognize that the ER, EM, and atk% substats probably can make up the difference, but im just using these as an example. In a lot of cases, the other 3 substats will be close to or completely dead, and crit matters more anyway.
Conclusion: When comparing two artifacts of the same Set & Main Stat, you should always use the artifact with the highest Crit Score when possible, and use other substats as tie-breakers.
Now, I’m going to build off of what I talked about in the previous section and explain how I weigh artifacts in isolation, rather than being compared to one another. This might sound pointless, but this is actually something you’d want to know how to do in order to decide whether or not an artifact is good or bad, and thus worth saving, using, or foddering.
Instead of calculating the crit score of an artifact, what I want to do instead is determine how rare it is. Exact probabilities of rolling an artifact with particular substats can be calculated but its a total pain and probably not worth the time. So what I do instead to judge the substats is, well, simply count the rolls. I will define an artifact “roll” not just as by what it upgrades, but also by what it starts with. For example, a +0 artifact that starts with flat defense, flat hp, and 3.9% crit rate, would, by my definition, have 1 crit roll.
reposting crit substat chart from earlier for reference
Its also important to note that, since an artifact has 4 substats, the most amount of crit rolls any one artifact can have is 7/9 rolls, which would mean you had a piece that started at 4 subs at +0 and only rolled into crit. This is why those are so valuable, by the way. It is possible to reverse engineer the exact roles, but instead im going to be lazy and just roughly estimate by dividing cdmg by 6 and crate by 3. Now for some examples.
Now, even tho this is a flower, which is less rare than sands/goblet/circlet, we can see that it still has 6/8 crit rolls! Which is actually really rare! So I would never fodder an artifact like this >->
Now for circlets, they cannot have the main stat as a substat, so a circlet like this, with 3 crit rolls and a cdmg main stat, is also super rare. In general, I would never fodder any circlets that have a crit main stat and 2 or more crit rolls.
This is an atk% sands with about 3-4 crit rate rolls. Since its hard to get the right main stat with sands/goblet/circlet, I would be far less picky. 12% crit rate doesnt look fantastic but itll get the job done. I wouldnt fodder an artifact like this, ever.
So this is an example of what I’d consider either a support artifact or, well, fodder. The substats look really good, but I would never put this on a main dps, as the most it could ever have is 2 crit rolls, which is far too few. The other substats are nice to have as bonuses, but not in the overwhelming capacity such as that.
Everyones account is different. Everyones goals are different. If you’re a casual player, I would say that maybe an artifact with 2 or more crit rolls is all you need, with the right main stat of course. If you’re a huge whale, max refreshes a day, I would be a lot more picky, and maybe say 5+ crit rolls is where you want to be. For me personally, well, I’m somewhere in the middle. My minimum is 4 crit rolls on flowers/feathers and 3 on the other pieces. I have full cleared abyss using that metric, so no, you don’t need whale levels of gear to beat this game.
Conclusion: When appraising an artifact, simply count how many rolls (as defined above) of either crate, cdmg, or other valuable stats you may want, out of the total number of rolls on the piece. It’s less accurate but wayyyy simpler and faster than doing actual math 😀
Edge cases + more detail for other sub/main stat comparisons. Spoiler-marked so I don’t throw a wall of text at you, no actual spoilers.
While it highly depends on your character, build, and weapon, a high ATK% substat can be comparable, but ultimately worse, than an equal cdmg roll. This can be true for EM too, but only for reactions. And some characters want to have a certain amount of ER in their kit, such as Xiao for example. I think that a high difference in crit score; say a pc with 20% ER / 10% crit score vs a pc with 30% crit score, its best to always go with the higher crit artifact. Differences within a margin of 5% crit score, tho, I think its ok to value the other substats in that case. As stated above, I think ER/EM/atk% should really only be used as tiebreakers. This is less true for supports tho, who need a lot of ER at times. For counting rolls, you can weigh these subs as .5 or .25 etc.
1:2 crit ratio
There will also be edge cases where you may have an artifact with a lower crit score than another, but your build is missing either crate or dmg. In these cases, depending on the quality of the artifact, I’d either use the lower crit score piece temporarily or just look to replace a different piece in your build to try and find the missing stat elsewhere.
The general rule I hear about set bonuses is Main Stat > Substats > Set bonus. I have no reason to disagree with this. If the crit score of one piece is way higher, you should go ahead and use that instead, then farm more artifacts later to re-gain the set.
Different Main Stats
For sands pcs, some characters can get away with using an EM sands as opposed to an Atk%. In these cases, I recommend using the piece with, you guessed it, the higher crit score. I would, however, avoid using an ER sands on any DPS, regardless of how good the substats are, with the sole exception of Mona. As for goblets, 90% of the characters need the correct elemental damage type. I would not use an Atk% goblet unless the difference in crit-score was insanely high, but I also recommend you do the math yourself on a dmg calc. Some characters, like Xiao, can actually get away with using an atk% goblet more easily, but this is only because of how damage modifiers work, and I don’t want to get to in detail with that right now. For a rule of thumb, if a character has their own steroid ability that increases their damage, Atk goblets will be more comparable to elemental ones, but still worse. And lastly for circlets, the crit score rule applies to crit circlet main stats as well, so, unless you are going to completely lose the 1:2 ratio, go with the higher crit score circlet. For counting rolls, a crit circlet can only have the opposite crit stat as a substat, so its actually more valuable.
Crit rate more valuable than crit damage? it can be argued that crit rate is actually a lot more valuable than crit damage, for two reasons. First, excluding some 5* character ascension stats, every character starts with 50% damage but only 5% rate. Second, no other stat can substitute for low crit rate, but low crit dmg can be mitigated by heavy EM or ATK%. I didnt try to touch this here, but just something to think about ^^
Now for some quick fun! I guess? If you want to judge an entire artifact set (based off of crit) you can apply all the same stuff. Just click on ARTIFACT DETAILS and then add the doubled crate to the cdmg. This is a good way to tell how much investment you have in a particular character. From what I can tell, 200+ percent crit scores from a set is about where a super high investment main dps will sit.
Anyway, I clearly have wayyyyyy too much time on my hands, and this probably went into way more detail than it needed to. for a tl;dr, compare two artifacts by doubling the crit rate and adding it to the crit damage (from substats) and picking the one with the higher score, and if you judge an artifact in isolation, count the crit rolls (or other valuable stat rolls), but be sure to count what it started with as well.
If anyone wants help with artifacts in general, or has any other genshin late-game questions, or wants me to clarify anything I said, or just wants me to do the work for them, lmk in the replies and I’ll get to u when I can >—<
Will probably edit this a bit, particularly the very last section, for clarity. Ill keep track of those edits here.
