Blizzard hasn't published fishing-specific details for these systems. The camp objects' skill, materials and effects below match the live game client (ForeverDB, build of 7 November); everything else comes from beta-era guides.

How camp objects work

Each needs a Campfire nearby, and all camping features share a one-hour cooldown. The 8% stat bonus is mutually exclusive with Blessing of Kings. A Fishing Rack or Fishing Hut can be placed over a Fish Bowl to replace it. Live

Guides add that you sit by it for one minute to get a one-hour buff. Beta

Unknown: which fish the Rack and Hut unlock, and how much their lures add. Warcraft Tavern says only that the Rack and Hut unlock as your skill rises, without thresholds.

Find Fish

A new tracking ability that shows nearby fishing pools on the minimap. Wowhead Forever lists it as a tracking aura. The sources don't say how you learn it.

Schools and wreckage

Schools of fish and floating wreckage appear at higher skill, usually near coasts, lakes and rivers. They can hold rare fish, materials and 14-slot bags.

Bloated fish

Ten kinds, from Bloated Brilliant Smallfish to Bloated Whitescale Salmon, are now uncommon quality and bind on pickup. Right-click to open them.

Chef's Knife and Seasonal Fish Steaks

A Chef's Knife (about 82c from many vendors, including Old Man Heming) cuts Raw Winter Squid or Raw Summer Bass into Seasonal Fish Steaks, which the Fishing Hut needs. Guides place it around skill 275.

Legacy perks for anglers

  • Luremaster (2 ranks): while a lure is active, 25% chance of an extra fish (50% at rank 2). A reading of the beta client files gives 50% without mentioning ranks. Beta
  • Working Overtime (5 ranks): +4% skill-up chance per rank, up to 20%, for any tradeskill.
  • Dedicated Study: +1 to your lowest tradeskill once per 23 hours. Warcraft Tavern adds that once all five of your tradeskills are at 300, it gives 3 random Elemental Essence instead.

Fishing is a secondary skill, and the guides read that as earning no Legacy Points by itself.

Trophy fish

Two beta-data guides report that trophy fish (lobster, mud snapper, salmon, catfish, redgill, yellowtail, mightfish) now sell to vendors for about 1 silver per pound, many times their Classic price. Not yet confirmed on live servers. Beta
