Zenless Zone Zero Shiyu Defense Full-Star Guide
Shiyu Defense is basically Zenless Zone Zero's endgame exam. Everything before it you can muddle through, but this is where your investment and team building actually get tested. When I first went for full stars I wiped over and over, not because my teams were weak, but because I was missing a bunch of small things. Once I learned its habits, full stars stopped being mysterious. Here's the stuff I died learning, plus the approach that worked, all of it paid for in runs.

What Does Full-Star Shiyu Defense Depend On?
Full stars aren't about brute-forcing raw damage, the mode has its own logic. Get a few hard requirements straight and you'll know where to push, instead of grinding blindly.
- Read the current buffs: Each rotation changes, the bonuses and enemy weaknesses are listed, don't skip them.
- Hit the right element: Matching elements does a lot more, and hitting resistance loses about twenty percent.
- Time is the judge: Full stars come down to clear time, slow play loses stars.
- You need two teams: Later floors want two squads, no duplicate characters, so spread your investment.
These are the floor for full stars, miss one and you'll wipe. Especially the current buffs and weaknesses, plenty of people ignore them and throw their old team at it, then wonder why their damage vanished. Reading each rotation first matters more than anything.
How Do You Split Two Teams for Shiyu Defense?
Once you hit the floors that need two teams, the real headache is how to split your roster. A lot of people cram every strong character into one team and leave the other useless, then neither side full-stars.
- One carry per team: Put one damage core in each squad, don't stack two carries together.
- Give each a stunner: Every team needs a Daze builder, or you never get a damage window.
- Spread the supports: Don't pile every buff on one side, let both teams benefit.
- Don't split evenly: Send your strong team to the hard floor and let the weak one grind the easy side.
Splitting teams is one idea: give both sides a full damage loop. Stacking two carries is a waste, split them up, pair each with a stunner and a support, and both sides can full-star. Sort the teams before you enter, it saves way more time than trial and error inside.
What Details Matter for Full-Star Shiyu Defense?
Once the big direction is right, the last few details decide it. Full stars and almost-full usually differ by the small stuff.
- Burst after the stun: Build Daze first, then dump ultimates and chain attacks once they're staggered.
- Don't skimp on drive discs: Crit rate, crit damage, and attack first, the right substats change damage a lot.
- Check faction bonuses: Same-faction teams get discounts, easy to miss early on.
None of these matter on their own, but stacked together they're ten to twenty percent of your damage. Full stars come from squeezing out every one of these edges, that's how you clear when someone else falls just short.

How Do You Practice for Full-Star Shiyu Defense?
Full-star practice isn't about hand speed, it's about familiarity and planning. First get your carries to the level the current patch expects, weapon, level, and core skills maxed. Don't spread your resources too thin. Then drill one fixed damage loop into muscle memory: build resources before the stun, dump everything once they're staggered, chain attacks in order. Once that loop is smooth, the damage follows. When a rotation updates, spend a few minutes reading the buffs and enemy weaknesses and adjust your teams, it beats bashing your head against the wall. And if you're just a few seconds short, claw those seconds back: stop over-moving, don't whiff skills, don't waste your ultimate. Full stars usually come down to those last few seconds.
Full-star Shiyu Defense is a slow grind, investment, team building, and the small details all have to line up. Don't expect one team to carry you forever, the buffs change every rotation, so adjust. The day you can build two teams on your own, read the weaknesses, and full-star without a guide is the day you've actually mastered the endgame. After that it's just showing up every rotation and collecting the reward.
