The Blood Moon Rises quest in OSRS should take a few hours for most players, with some guides and discussion putting it in the roughly 2–6 hour range depending on how quickly you solve the steps and whether you already know the route.

What affects the time

  • Quest knowledge: Familiarity with the Myreque-style quest flow can cut the time down a lot.
  • Combat and travel efficiency: Faster movement, teleports, and combat gear help shave off time.
  • First-time vs. guided run: A blind run usually takes longer than following a guide.

Practical expectation

For a normal player, I’d budget about 3–5 hours if you’re doing it casually, or closer to 2–3 hours if you’re efficient and using a guide.

Note

If you meant a different “Blood Moon” quest or were asking about a non-OSRS game, the timing would be different.
