Fishing
The best source of food in the game is obtained through the Fishing skill. Fish offer varying benefits in addition to the regular hp/mana regen that you are used to. All fish that are caught must be cooked in order to be consumed. For more information, see the Cooking section.
There are 7 different tools available at NPC's found in most main towns. These tools are capable of catching different kinds of fish.
Each tool also has a fishing level requirement to use. Keep in mind - the higher your fishing level, the better you get at catching specific fish!
If you're lucky enough, you can catch better versions of most fish.
In addition to this, each tool has a chance to catch something lucky. The higher level of tool that you are using, the greater the chance of this increases.
Treasure Chests can be caught as Common, Rare, Epic, and Legendary. Each tier with varying rewards.
Magic fish restore instant mana, similar to a mana fluid, in addition to normal food regeneration.
Groupers will give you a timed exp buff!
