To make tier 3 weapons in OSRS Corrupted Gauntlet, you usually craft a tier 2 weapon first, then upgrade it twice at the singing bowl once you have the right materials and weapon frame. The common prep flow is to grab a weapon frame early, gather shards and resources, make the first weapon, then finish the upgrade into tier 3 after you’ve looted enough demi-boss drops and materials.

Basic flow

  1. Get a weapon frame early by killing small monsters.
  2. Collect enough shards and resources while moving around the map efficiently.
  3. Make a tier 2 weapon at the singing bowl.
  4. Kill the demi-bosses for weapon upgrades.
  5. Return to the singing bowl and upgrade the weapon to tier 3.

Practical prep tips

  • Aim to collect plenty of shards while you move; the guides emphasize shards because they gate both upgrades and teleports.
  • Demi-bosses only matter in the middle rooms of each side, so there’s no need to waste time checking corners.
  • If you’re short on time, go for the first workable weapon upgrades instead of being picky, since you can break extras down for shards.
  • Many players prefer staff and bow first because ranged or magic can be easier during prep, especially if you’re still learning.

How it usually feels in-run

A typical run starts fast and a bit messy: you sprint the center, tag monsters for the frame, grab resources on the way, and rush back to craft. After that, you keep pushing outward for demi-bosses and resources until you have enough to finish the tier 3 weapon and, if possible, some armor and food.

Note on the query

Your wording sounds like you mean Corrupted Gauntlet tier 3 weapons , not a general OSRS smithing recipe. The guides currently circulating are mostly video walkthroughs and prep routes rather than a single fixed recipe, because the process depends on the run and what materials you collect.

If you want, I can turn this into a simple step-by-step CG prep route for bow, staff, or halberd-style runs.
