So you want to learn to fish....

[Fox the Clever]

Yes, a blessed fishing pole can indeed break when you use it for fishing. Given the relative difficulty of obtaining one of those fishing rods, this is obviously a bad thing. Personally, I always use a summoned Brell's fishing pole to do any fishing I require (for me, that's usually fishing for cobalt cod in Cobalt Scar, as an ingredient in making arctic wyvern hide armor). That way, if the fishing rod breaks, I simply summon another one. No more making your way back to a vendor to purchase a new fishing rod!

bait maker might be a usefull tool to carry around while you fish, token it when your not, see the tinkering threads for the recipie

[Kumudil]

The device mentioned is the: Anizok's Bait Dispenser.
Most fishes can be pressed to new Bait with this nice device. Together with the fisherman's companion you get complete independent from NPC's and can fish wherever you want for infinite time.

For evil races, The Feerrott is good. Kogg has bait and is standing by the river, although, you'll have to go to Oggok for a pole from Angrog. For Iksar's Calibas East is full of water and Klok Foxmyr and Dytar have bait and poles.
