So, you've pulled the galaxy's luckiest gambler, Aventurine, and you're ready to let it ride? Let me tell you, my fellow Trailblazer, this man in the fancy hat is more than just a pretty face and a stack of shields. He's the centerpiece of what I like to call the "Follow-Up Frenzy" – a team composition so synergistic it feels like you're cheating. I mean, who doesn't love seeing extra attacks pop off without even taking a turn? It's like getting free dessert with your meal. But who are the best partners-in-crime for our Preservation powerhouse in 2026? Let's shuffle the deck and find out.

First, let's break down why Aventurine is such a hot ticket. He's a Preservation unit who doesn't just sit there and take hits—oh no. He builds shields, yes, but his damage scales off DEF (talk about efficiency!), and his secret sauce is his follow-up attack. Every time he or a teammate gets smacked, he gets a point towards a big, flashy follow-up. His A6 trace is the real kicker: he also gets a point when any ally performs a follow-up attack. See where I'm going with this? It's all about building a team that triggers this effect constantly. So, who makes the cut?

🃏 The S-Tier Follow-Up Synergy Squad

These characters don't just work with Aventurine; they create a feedback loop of glorious, out-of-turn violence.

1. Dr. Ratio - The Intellectual Enabler

   

   Is it any surprise the genius doctor tops many lists? His entire kit is built around dishing out follow-up attacks after debuffing enemies. Pair him with Aventurine, and it's a match made in the Imaginary cosmos. Not only do you get double Imaginary damage for breaking tough enemies (remember those pesky True Stings?), but every time Dr. Ratio does his scholarly smackdown, Aventurine's follow-up bar fills faster. It's a beautiful, logical partnership.

2. Topaz & Numby - The Follow-Up Feedback Loop

   

   If you thought Dr. Ratio was good, wait until you see this. Topaz and her piggy bank are a follow-up attack machine. Every single one of her attacks counts as a follow-up. So, Aventurine's bar is filling up non-stop. But here's the magic: when Aventurine finally unleashes his follow-up, it advances Numby's action forward, which then triggers another follow-up for Topaz, which gives Aventurine another point... It's an infinite cycle of economic violence! This is absolutely brutal for content with tight turn limits, like Memory of Chaos or the new Divergent Universe challenges.

⚡ The Meta-Defying Power Couple

1. Acheron - The Nihility Queen

   

   "But wait," you say, "doesn't Acheron need two other Nihility friends?" Well, my friend, rules are made to be broken, especially by gamblers. At E0, you can replace one of those Nihility slots with Aventurine. How? Equip him with the Trend of the Universal Market light cone. Every time he gets hit (and as a Preservation unit, he will), he applies a Burn debuff, granting Acheron her precious Slashed Dream stacks. If you're feeling extra lucky and have his signature light cone, his follow-ups apply a damage vulnerability debuff, making Acheron hit even harder. He shields, he debuffs, he enables—what more could you ask for?

💎 The Stellar & Accessible Picks

Not everyone has every limited 5-star, right? Fear not! The standard banner and 4-stars offer fantastic options.

1. Clara - The Counter-Punching Duo

   

   Here's a classic. Every time Clara is hit, Svarog counter-punches, and that counter is a follow-up attack. With Clara on the team, Aventurine's follow-up gauge will be constantly ticking up. Sure, they might compete for enemy aggro a bit, but it's a good problem to have. Clara's Ultimate increases her taunt, and even if Aventurine gets hit instead, his trace gives him two points towards his follow-up. It's a win-win brawl.

2. Himeko - The Erudition Engine

   

   Another standard banner gem. Break an enemy's weakness, and Himeko gets a charge. Get three charges, and she unleashes a massive AoE follow-up attack. In fights against fire-weak enemies, or better yet, enemies weak to both Fire and Imaginary, she can trigger this frequently, feeding Aventurine's kit perfectly. A fantastic budget option for the follow-up playstyle.

3. Herta - The Pure Fiction MVP

   

   Don't you dare sleep on the genius! She's free, and in the right mode, she's a monster. Her follow-up triggers when any enemy drops to 50% HP or lower. In modes like Pure Fiction with swarms of weaker enemies, she can chain follow-up attacks endlessly. Pair her with Aventurine, and you have a near-perfect, easily accessible clearing team. Plus, freezing enemies is never a bad thing.

❄️ The Universal Support Wild Card

1. Ruan Mei - The Harmony Catalyst

   

   What's that? She doesn't do follow-ups? Exactly! She's here to make everyone else's hits—follow-up or otherwise—hurt a whole lot more. Ruan Mei is the ultimate luxury support. She boosts team damage, Weakness Break efficiency, and extends the duration enemies stay broken. With Aventurine's SP-positive nature (he rarely needs to use his skill), you'll have plenty of skill points to feed Ruan Mei and your main DPS. She amplifies Aventurine's own respectable damage and ensures your hyper-carry, whether it's Ratio, Acheron, or anyone else, obliterates everything faster.

🎲 Final Bet: Building Your Team

So, how do you put this all together? It's simple! Think of a core duo and build around it.

Your Goal	Core Duo	Flex Slots	Perfect For...
Max Follow-Up	Aventurine + Topaz/Numby	A Healer/Debuffer (e.g., Gallagher, Pela) + Flex DPS	Memory of Chaos, Simulated Universe
Imaginary Breaks	Aventurine + Dr. Ratio	A Nihility Debuffer (e.g., Welt, Pela) + Harmony (e.g., Sparkle)	Boss Fights, Elite Enemies
F2P Friendly	Aventurine + Herta	March 7th (Preservation) + Serval/Asta	Pure Fiction, Early Game
Ultimate Sustain	Aventurine + Clara	A Harmony (e.g., Tingyun) + Healer (e.g., Lynx)	Auto-Battle, Long Sustain Fights

The bottom line? Aventurine is one of the most flexible sustains in the game. Whether you're chasing the high-roll meta with Topaz and Acheron or making do with the reliable Herta and Clara, he slots in and makes your team significantly better. His shields keep you safe while his passive damage and follow-up potential turn defense into a devastating offense. Now, go place your bets and watch those follow-up attacks rain down! 🎰
