Why the All-Out Attack Button on Event Bosses Traps New Players

Every few weeks, a fresh round of players storms an event boss and slams the All-Out Attack button the moment the burst gauge fills. They watch the flashy sequence, see the damage numbers explode, and walk away convinced they played the fight correctly. The leaderboard then posts, their ranking sits near the bottom, and the same players wonder what went wrong. The All-Out Attack button on an event boss in Princess Connect! Re:Dive feels like a reward for filling the gauge, but for newcomers it works more like a lure than a tool.

The feature looks simple. After stacking TP through normal attacks, skills, and unite attacks, your party tops up the shared burst meter. Once it hits 100 percent, every character unleashes their most powerful move in sequence. The screen lights up, the voice lines fire, and the boss takes a heavy blow. The button is positioned front and centre, glowing and waiting, and that visibility is exactly where the trouble starts.

What follows breaks down why that glowing button is usually the wrong choice during your first attempts, how Australian players juggle it around event schedules, and the rare moments when it is genuinely worth pressing.

What the All-Out Attack Actually Does in Combat

Tapping the button at full gauge triggers a forced sequence where each character on your team fires their union burst back to back. The game skips normal attack animations and pauses the boss's turn briefly, stacking all that damage into a single window. On paper, that sounds unbeatable.

In practice, the damage gets capped by the boss's damage ceiling in most event fights. That ceiling exists to keep scores from running away and to create a window where only the final seconds matter. Emptying your gauge the moment it fills usually means half your bursts land before that window opens. The result is a lot of sparkles and a modest total on the scoreboard.

Why New Players Are Wired to Mash the Button

The button glows, the meter is full, and the audio cue kicks in. After a long shift at a Sydney café or a study session at a Melbourne library, your brain sees the full bar and reads it as a green light. Many rookies also believe that using a resource as soon as it appears is always correct, the same logic they bring to gacha pulls.

There is also a social pull. Some of the voice actor highlights from the anime make those union bursts feel like a reward in themselves. New players chase the audio and the animation, not the damage math.

The Hidden Cost of Burning Your Burst Gauge Too Soon

Your burst meter does not refill instantly. After unleashing the All-Out Attack, you spend a long stretch tapping basic attacks, waiting for skills to come off cooldown, and praying your tank survives. During that lull, the boss charges its own mechanics, stacks debuffs on your backline, or wipes your support units.

Players who run the game on mobile data during a commute on the Sydney or Melbourne train lines often notice this drop-off. The screen goes quiet, the meter slowly trickles back up, and the boss punishes every second you spent celebrating too early. That quiet stretch is where most wiped runs actually start.

Reading the Boss's Phase Transitions Correctly

Event bosses in Princess Connect! Re:Dive usually have two or three phases, each announced by a voice line and a visual cue. The damage ceiling often opens up in the final ten or fifteen seconds, lining up with the boss's last health bar. Hitting All-Out Attack during phase one or two dumps your damage into a capped section and leaves nothing for the real window.

Watching replays from top-ranked guilds on local Discord servers, you see them spend most of the fight charging, conserving skills, and only tapping when the boss drops below the threshold. They treat the glowing button as a final exam, not a free hit.

Saving the Burst for the Damage Window

The cleanest approach is to ignore the meter entirely until the boss hits its last health gate. Skills, union bursts, and TP-boosting support units should still charge the gauge, but the All-Out Attack itself stays untouched. Once the window opens, you tap, the sequence runs, and your score jumps dramatically.

Timing this also means planning around AEDT event resets. Most limited bosses drop new phases at 7pm AEST, right when many Australian players are wrapping up dinner. Pre-loading your team, checking your support units, and queuing the burst for the final window turns a decent score into a competitive one.

When the Button Is Worth Pressing Early

There are real exceptions. Some fights require burst damage to interrupt a boss mechanic, such as a one-shot ultimate or a stacking shield. In those cases, pressing early is the only way to survive the next ten seconds. Other times, your team is simply too weak to last until the final phase without bursting first.

The same logic shows up in unrelated mobile hits. Players chasing block blast speedrun records learn that burning a combo too early costs them the run. Both games reward patience over impulse.

Building a Team That Sets Up the Perfect Burst

A team built around a delayed burst carries a TP booster in the front line, a damage dealer with a union burst that scales with TP, and a healer who keeps the front line alive through phase one. The booster charges the meter without wasting the gauge, the dealer waits for the window, and the healer buys the seconds you need.

Over time, you will recognise which bosses punish early bursts and which reward them. Treat the All-Out Attack as a scalpel, not a hammer, and your rankings will climb without any extra top-ups on your credit card.

Take a few minutes before the next event starts to review your roster, queue your support units, and decide in advance when you plan to tap that glowing button. The choice you make at full meter is the one that decides whether you climb the leaderboard or watch someone else's name sit at the top.
