Lucky you for getting Eula! What now? After devoting all your resources, Primogems, and unrequited love for pixels into her, which weapon do you give her? That's even a bigger conundrum than whether one should skip her banner or not. Joking aside, Eula can be rather picky with her stuff. That's probably why she received a personalized sword.
Without the proper setup, then she's not much better than other Mondstadt DPS characters who are in dire need of buffs. With the number of claymores around, it can be dizzying to do the theoretical and practical math needed to determine which among them gives the biggest numbers. So which of these big sticks will make both you and Eula get your money's (or sanity's) worth?
10 Royal Greatsword - Average
This is not the best nor the most available weapon for her but if you like the look of the Royal Greatsword, then by all means - use it. It's not that bad as a weapon for Eula as it gives out ATK stat increases as well as a big bonus to the CRIT Rate.
However, keeping this CRIT Rate bonus can be tricky -- especially considering Eula's huge damage numbers come in a delayed manner. One good reason to stick with this one is if you've already leveled it to 80 and are too lazy to grind for another weapon.
9 Lithic Blade - Better With A Specific Team
The Lithic Blade is in a similar spot to the Royal Greatsword but it can be more consistent especially if players manage to include a full Liyue retinue for Eula. The blade gives out some significant buffs for each Liyue character.
Even Zhongli, Beidou, or Qiqi can supplement Eula's party to that end but do note that there are better options for party members. Limiting team composition choices just to maximize the Lithic Blade for Eula is counterproductive if you have better options.
8 Blackcliff Slasher - Best For Big Mobs
What would those better options be? Let's start with Blackcliff Slasher. Like the Royal Greatsword, it can be readily obtained via Paimon's Shop. Its secondary stat is CRIT DMG which is always awesome for Eula or even any DPS character.
The problem with it is that the weapon perk is incredibly inconsistent or even difficult to attain. It requires killing an enemy to get an increased ATK buff that stacks pretty high. For boss fights like Azhdaha or the Primo Geovishap, you can forget about this buff. Still, it's decent enough if you have low CRIT DMG.
7 Snow-Tombed Starsilver - Matches Eula
One of the most aesthetically complementary weapons for Eula would be the Snow-Tombed Starsilver; it also appears to have been made for her. Eula can take full advantage of the weapon's perk and maximize that icicle damage frequently.
Moreover, the secondary stat is physical damage, making it appealing for her. Truth be told, it's one of the three best budget options for Eula. This weapon, as well as the next two, don't have many differences in damage output, so pick the one you like the most.
6 Prototype Archaic - Great For Free Players
The other best budget weapon for Eula is the Prototype Archaic. It's arguably easier to refine, making it a preferable choice for free players. The Prototype Archaic gives out tons of ATK boosts and even more with its perk.
Since Eula has faster attack animations compared to other claymore users, she gets to activate this weapon's explosive damage every 15 seconds. It's by far one of the simplest weapons she can utilize with no drawbacks and no conditions.
5 Serpent's Spine - Risk & Reward
Still, some weapons that give out negative conditions can yield better damage outputs for that high-risk, high-reward gameplay. Serpent's Spine, available in the Battle Pass, is a semi-budget option that gives out a hefty amount of CRIT Rate.
More than that, it also grants Eula an increase in overall damage the longer she's out in the field. The downside is that she will also take more damage. However, since one of her staple supports is Diona and Xinyan -- both of whom are shield-generators -- Eula should be safe. Refining this weapon requires quite a deal of patience though.
4 Skyward Pride - A Solid 5-star Weapon
Skyward Pride is the most underrated out of all the 5-star claymores thanks to its Energy Recharge secondary stat. Still, Eula actually needs this stat since her Elemental Burst costs 80 and her innate energy generation is a bit lacking.
Moreover, when one factors in the vacuum blades that the Skyward Pride gives upon Elemental Burst activation, then it pretty much matches the other 5-star weapons. It also matches her aesthetics well enough.
3 The Unforged - Rare But Excellent
For most players, The Unforged isn't an option anymore as its banner hasn't come back yet. But it was actually one of the best claymores even though it's rare. It was made for parties with a shielder in them since any character with a shield who uses this also gets increased ATK.
As mentioned before, Eula's supporting characters are mostly shield-generators and Diona is one of her most recommended characters. So if you have unforged, consider yourself lucky as it's one of the best and most carefree weapons for Eula.
2 Wolf's Gravestone - Second Best Is Pretty Good Y'all
The edgy black and red might not fit Eula's motif and theme but the Wolf's Gravestone is actually on par with Eula's best-in-slot weapon -- Song of Broken Pines. It just gives out so much ATK boost that it measures up well against Eula's latest toy.
In certain instances when the Wolf's Gravestone's passive is activated, it can even out damage Song of Broken Pines. Needless to say, if you were fortunate enough to have gotten this weapon, then there's no need to go broke for the latest 5-star claymore (unless you care about appearances).
1 Song of Broken Pines - Broken Spines?
At first glance, it appears like Song of Broken Pines was going to be a "Staff of Homa debacle" except for Eula; it could have made her absolutely broken as in Hu Tao's case. However, Song of Broken Pines turned out to be relatively modest.
It didn't shake up Wolf's Gravestone's spot on the throne too much despite the Physical DMG secondary stat and the attack speed increase. Nevertheless, it's simpler to use than Wolf's Gravestone since there's no need to manage the enemy's HP bar. Eula can just dance to the sound of her pulverizing their broken spines. That could even be where the weapon's name came from.
He just can't seem to catch a break!
