How to beat stage 11-30

This page is lighter than our 10-30 guide. Community guides consistently treat 10-30 and 11-30 as a pair — the video walkthroughs cover both in one go — but we could not find a source that publishes 11-30's boss or mechanics separately. What follows is what carries over, plus honest gaps.

What carries over from 10-30

The 10-30 fight is won by positioning rather than Combat Power: squad dragged into a corner so the boss has less room to escape your damage area, adds kept grouped, immediate regrouping after knockbacks. Guides covering both stages apply the same approach to 11-30.

The same role split applies too:

| Failure mode | What to change | |---|---| | Timing out | Add defence reduction (Devil, Dark Choco) and more single-target damage | | Dying | Add sustain (Herb) and damage reduction (Nameless Cake Hound) |

Where our data helps

If you cleared 10-30 and stalled here, the likely gap is synergy coverage rather than levels. Check your squad in the Team Builder — it lists every skill on your team whose synergy nobody supplies, and names the cookies that would fix it.

Two synergies to watch: Range is wanted by 18 cookies but supplied by only 4, and Duration is wanted by 14 and supplied by 3. Those are the two most likely to be quietly missing from a team that looks fine on paper.

What we do not know

11-30's boss identity, its mechanics, and whether it introduces anything 10-30 does not. Treat this as "the 10-30 approach, applied again" until someone documents otherwise.
