The boss & P-rank
checklist.

The official Roblox page shows challenge badges. Badge names prove a challenge exists, but they do not explain its full unlock route.

Six badges checked against Roblox data

Roblox's badge list for this exact game shows the six P-rank names below. A badge proves a challenge exists; it does not reveal the full route, score rules, or unlock steps.

0 of 6 marked for practice

The last three were created or updated around the October 17 update. That timing suggests a connection, but Roblox does not provide full patch notes, so we do not claim which fights arrived in Update 5.

How to research a boss before an attempt

  1. Open the official Roblox game's badge list and choose the badge you want.
  2. Read the badge description when one exists. The last three badges currently have no public description.
  3. Enter that battle and learn its attack cues and on-screen controls.
  4. Record what ends a run, then adjust one action at a time. Do not assume a strategy from a different DELTARUNE fan game will work here.

A practical P-rank practice loop

Work on one fight at a time. First learn to finish it consistently. Then note the attack that causes most mistakes. Practice that segment and compare results across attempts. The game may grade more than survival, so check any rank feedback shown at the end of a run before assuming a no-hit attempt is enough.

We have not verified the exact P-rank conditions, damage thresholds, or unlock order. A guide that invents these would waste your time.
