Here,just like what you have seen the title,it is a lineage fishing guide for you.Read it at once.

First off, to start fishing you need to locate the Fishermen's Guild members, so far I've noticed that they are all located in harbors and magic shops in towns.
[Fishing Rod]

First off you need a fishing rod, They vary in grade and price also they need different level of fishing shots. The difference between them is apparently that the amount of damage you deal to the fish.

Prices
Baby Duck Rod (NG): 36k
Albatross Rod (D): 120k
Pelican Rod ©: 480k
Kingfisher Rod (B): 1.44m
Cygnus Pole (A): 4.8m
Triton Pole (S): 12m

[The Lures]

Now about the lures, there are three different colors, Yellow, Green, Purple. All three of them have three different grades, Low, Medium, High. The difference between grades is that the higher grade has a slightly higher chance to pull up better fish, also the fish bite much faster. There are also three beginner lures. But they are a bit special ? they will show you which skill to use (see [How to fish]) when you fish with them. The downside is that they seem to only pull up a low type of fish. However, they are awesome to use if you're fishing for the first type; buy 20 or so of 'em and try it. All fishing rods use the same lures, so at higher levels it will be cheaper in the end to fish.

So much it is,if you wanna know more about the lineage fishing guide,you can following the link and get more details.
