Arena & Scrapbook

Arena fighting and scrapbook hunting spend the same free fight, so they are one system, not two. Whichever is worth more gets the fight.

Arena and Scrapbook

How a target is chosen

Every cycle the bot gathers candidates from three places at once:

  • the three opponents the arena offers you
  • the player pool it has crawled and cached
  • the Hall of Fame around your own rank

Each candidate is scored on one scale:

(missing scrapbook items × 100  +  daily XP × 60  +  rank gain × 25)  ×  win chance

and the best one is fought. Scrapbook items first, then the ten daily XP fights, then climbing the ladder — but a target you are unlikely to beat is worth less than a slightly worse one you will, which is what multiplying by the win chance does.

TIP

This replaced a chain of thresholds, and the difference matters more than it sounds. A chain of conditions can reject everything and leave the bot doing nothing at all; a ranking always has a best entry. If your arena ever "just stopped", that was why.

Watch it think

The Arena page shows the decision rather than only the result: how many candidates came from each source, a bar per candidate split into items, XP and rank, dimmed by the share the odds take away, and the winner highlighted.

During the cooldown it shows what it will fight next. When it is not fighting, it says why in one sentence instead of leaving "Ready" on screen as the only clue.

Free fights are free

The minimum win chance applies only when a mushroom is being spent. The free fight's cooldown runs out whether you use it or not, so refusing to take it because the odds are middling wastes it.

That is worth knowing if you ever set the minimum high and wondered why nothing happened: the setting only ever governed paid fights.

Realistic targets

The scrapbook level window scales with your own level. A level 20 character is not offered level 600 players any more — the range widens as you grow, roughly 20% above and 50% below, with a floor of a few levels so low-level characters still have somebody to fight.

Rarer items count for more than common ones, so free fights go to the pieces that are actually hard to find.

Scrapbook collection

Targets the simulator rules out are not retired for good. The verdict expires once you have outgrown it — roughly 5% more total attributes — and the app says so when the pool recovers.

Battle simulation

A full round-by-round replay of any fight: damage dealt, crits, dodges, and HP over time. Useful for understanding why a fight went the way it did, not just that it did.

The same simulator is what produces the win chance in the scoring above, so what you see in the replay is what the bot was reasoning about.

Turning one of Auto Arena or Auto Scrapbook off narrows what the module looks for. Turning both off switches it off entirely.
