You know, it's kinda wild when you stop and think about it. Some of the absolute best supports in Teyvat, the ones everyone raves about – Furina, Bennett, Kazuha – they all have one thing in common, right? Yep, they're all sword users! ⚔️ Now, along comes Xilonen, this fantastic Geo support joining us in Natlan (can you believe it's 2025 already?), and guess what? She’s wielding a sword too. But here’s the fascinating twist about her: unlike a lot of characters who desperately need specific stats funneled into them, Xilonen’s core buffs are flat bonuses tied purely to her Elemental Skill level. That sounds like freedom, doesn’t it? Just slap any old sword on her and call it a day? Well... not quite. See, while she can function with various swords, choosing the right one can seriously elevate her game, either by boosting her own presence on the field as a surprising damage dealer or by enhancing her supportive capabilities even further through passives. It’s all about finding what fits your playstyle and team needs. Let me walk you through the options I've been tinkering with.
So, where do you even start? Xilonen scales beautifully with DEF – it fuels both her damage output and her healing. That immediately puts certain weapons in the spotlight. If you were lucky enough to grab it back in the day, Cinnabar Spindle is practically tailor-made for her. Seriously, that DEF secondary stat and its skill that boosts Elemental Skill DMG based on DEF? Chef's kiss! 😌 But hey, I get it, that event was ages ago (version 2.3 feels like ancient history now!), so it’s not an option for everyone. No worries though! Natlan brought us the incredibly accessible Flute of Ezpitzal. Just head to the local blacksmith, grab the blueprint, forge it up to R5, and bam! Using her Skill gives her a solid 32% DEF boost. It’s straightforward, reliable, and easy to get. For pure DEF stacking and team utility, the new Peak Patrol Song feels like her true signature, even if it’s not officially labeled as such. It boosts her DEF and her damage, and at max stacks, it shares a hefty All Elemental DMG Bonus with the whole party based on her DEF. It’s kinda nuts, honestly, and works wonders whether you lean into her DPS or support side.
But maybe you want her to hit harder? Like, really harder? That’s where Crit weapons come into play. Don't sleep on the humble 3-star Harbinger of Dawn. Yeah, its Base ATK is laughably low, but Xilonen doesn't care about ATK! What she loves is that massive 46.9% Crit DMG at level 90 and the R5 passive giving a whopping 28% Crit Rate if you can keep her HP above 90%. It demands good shielding or careful play, but the payoff? It can outpace some 5-stars. 🚀 For a more premium Crit DMG option, Uraku Misugiri (Chiori's signature) is a dream. It boosts Normal Attack DMG, Elemental Skill DMG, and gives DEF after nearby Geo damage. It synergizes perfectly with her kit and other Geo teammates. If Crit Rate is what your build craves, Haran Geppaku Futsu is a stellar pick. That Crit Rate secondary stat is always welcome, and its passive encourages using Normal Attacks – something DPS-focused Xilonen will be doing plenty of. It just feels smooth to use on her.
What if support is your absolute priority? Energy is often king. The classic Favonius Sword is basically the old reliable. That Energy Recharge secondary stat is pure comfort, and the passive generating particles for the team? It lets Xilonen battery herself and her teammates. Just remember to slot in a Crit Rate circlet to reliably trigger those particles! ⚡ Then there's the elegant Freedom-Sworn. Okay, yes, Xilonen doesn't inherently need Elemental Mastery. But... the passive is where it shines. By triggering Crystallize reactions (which she does naturally), she can activate the 'Millennial Movement' buff, giving the whole team a nice 16% Normal/Charged/Plunging Attack DMG boost and 20% ATK. It transforms her into a potent buffer beyond her base kit.
So, circling back to where we started, it's pretty cool how the sword keeps proving itself as the go-to weapon for powerhouse supports. Xilonen continues that legacy, but she does it in her own uniquely flexible Geo way. Whether you need her to be an unbreakable DEF-fueled healer and buffer, a surprisingly sharp Crit machine, or a smooth Energy-generating support, there’s a blade out there that fits. Experiment, see what feels good for your adventures across the ever-evolving landscapes of Teyvat, and let Xilonen slice her way into your team's heart!
