Unlike professions, you can obtain as many of the secondary skills as you wish, even if you already have two professions. These skills revolve around creating or finding items that will let you more easily heal yourself; theyre not usually highly lucrative and wont let you create equipment or long-term buffs.
Cooking is simple, albeit somewhat circumscribed at this point in the game. As a cook, youll be tasked with finding meat of various animals, ranging from the commonplace, such as boars and wolves, to the relatively obscure. (Meat drops off of beasts naturally; you dont need any other collection skills to find it.) When you have meat, you can bring it back to a fire or cooking rack to make it into food.
Most of the food that you can create is straightforward, of the sit, eat, and regain health variety, but you will eventually be able to make food that will buff your spirit and stamina for 15 minutes with each meal. This can be fairly useful, but it takes an awfully long time to get up to the higher levels of the skill, and when you do, you might find that many of the recipes youre interested in will also require a high level of fishing skill to acquire the ingredients in what can be an unpleasant bait-and-switch if you havent been spending a lot of time fishing.
First aid is likely going to be something that almost every player will want to pick up, mostly because its easy to use and lets you cut the downtime related to health drain, or lets you heal up your teammates, no matter what class you are, even during combat!
To start out with First Aid, youll need to gain the skill from a First Aid trainer, then find some cloth. Cloth (linen, wool, silk, etc) is a common drop on humanoid enemies, and can be made into bandages with your First Aid ability; these bandages can then be applied to yourself or to a teammate, and will heal your target over a short period of time. The best part of all this is that cloth is pretty easy to find, which makes First Aid an easy skill to build up, especially if you grab it at a low level. If you wait until youre a high level before you nab it, youll have to start out with the linen recipes before you can work your way up to the higher-quality cloth, which will either force you to buy a bunch of linen at auction or camp a bunch of low-level spawns, neither of which is a very palatable option.
Its important to remember, though, that applying a bandage is considered to be a channeling action. This means that your target (or yourself) wont get all of the benefits of the bandage right away; itll take around six seconds for the complete effect to be felt, during which time you can be interrupted if youre hit. (This prevents you from bandaging yourself during solo combat, by the way, or at least prevents you from getting the full effect of a bandage, as itll cut out as soon as youre struck by a weapon or spell.) Also note that when a bandage is applied, the target cant be bandaged again for sixty seconds. Thus, first aid is best used for either shortening the downtime between solo fights, or for healing yourself during combat when you dont have aggro, or for healing a teammate whos on the cusp of death. Youre never going to be able to match the pure healing power of a class with healing spells, and youll find that over-reliance on bandages will result in your running out of them at inopportune times, especially in instanced dungeons, but still - its a free skill that every non-healing class will find use for at some point or another.
Well, almost every non-healing class, we should say. The only reason you might not want to pick up first aid is if youre also a tailor; since tailoring requires large amounts of cloth, then youd have to be splitting your resources between two skills, meaning that youd be unlikely to excel in either of them. Since the classes that are most often tailors are mages (who can summon in food to heal themselves in between fights) and priests (who obviously have little need for first aid anyway), youre unlikely to miss first aid if you choose to be a tailor.
Whether you consider fishing to be merely boring, really boring, or brain-liquefyingly boring, will depend on your level of patience. After you receive your initial training in fishing, youll be asked to buy a fishing pole and optional bait. (Youll probably want the bait, as it greatly increased your fishing skill for a few minutes.) When you have a pole, you can walk up to the edge of a body of water and use your fishing skill to cast your line. If for some reason the water is unfishable, youll get an error message telling you so, so pack it up and head somewhere else when this occurs.
When youve cast a line, all you can really do is wait for your bobber to, well, bob; when you see it splashing around, right click on it to see what youve caught. The thing here is that your bobber will rarely splash before the timer drops below halfway, sometimes wont splash until the timer is almost done, and sometimes wont splash at all, forcing you to recast. The tedium really starts to set in when you realize that, even if the bobber does splash, youre not guaranteed to get anything; at low levels, at least, youre going to get an awful lot of "Your Fish Got Away!" messages.
The thing about fishing is that, if youre willing to put the time into it, youre going to find plenty of restorative items (fish that can be eaten like any other food), including some that are a bit more powerful than what you would normally be able to buy. If youre a real cheapskate, then, and dont want to have to pay for food, then fishing might be a good alternative for you, if youre willing to soak up some of your time with it. (You might also want to try out cooking and see which one is easier for you.)
In addition to plain old edible fish, you can also find inedible fish (these are useful in alchemy and can sometimes be valuable at the auction house), messages in bottles (usually containing scrolls of some sort), and lockboxes (which are rare, but will usually contain something decent). Of course, youre going to have to stand around by a body of water to get anything at all, unlike first aid and cooking, which at least have the benefits of letting you gain experience while you gather the materials required for them. Still, though, its relatively inexpensive to train yourself in fishing, so you might want to give it a shot and see whether or not you enjoy it.
