Crew skills are not tied to class

You can use up to 3 crew skill slots at one time. This includes up to 3 collecting skills, 3 quest skills, and 1 crafting skill like for swtor credits at the same time. The crew's three abilities are forever unrestricted. If you want, you can unlearn them and learn other things. However, if you're dreaming of returning to an unlearned skill, you'll need to level up from the beginning. If you don't master certain skills, you'll lose rare schematics and recipes, so think twice.
Crew skills are not tied to class. This means that you can use all the skills of the crew in any class. Also, don't worry, there are no seed bonuses to the crew's abilities like WoW and ESO.
Star Wars: Old Republic bread and butter send allies to missions. Crew members cannot be killed during a mission, but they may not succeed.
The number of companions you can send in a mission depends on your level. You can send 1 companion at level 10, 2 at level 15, 3 at level 25, 4 at level 41, and 5 companions at level 48 to the mission. Remember that crew skills are with you, not your partner. However, certain partners may have bonuses for certain skills. It is "love" and "effectiveness" that also affect the effectiveness of the mission. Higher levels of impact result in longer completion times, while higher efficiency vice versa.
Collect skillsIn the MMORPG genre, players are familiar with collecting skills, professions, jobs, or anything else called. These are basic skills that players can simply pick up and sell or use for crafting.
In general, the most used to develop in-game currency is to collect skills. The entry level is relatively low and no startup funding is needed (maybe spikes are needed) so you can start collecting resources right away.
ArcheologyIt's hard to know how far SWTOR Galaxy is out of our world, but I'm sure they have their own field of archeology. Star Wars: In the Old Republic, however, it's not about digging into the past to find some broken dinosaur bones and bowls, but rather finding fragments of crystals and relics. Crystals are mainly used in the manufacture and modification of lightsaber. Ancient artifacts may contain elements that incorporate the Force of Technology. In essence, these discoveries are most valuable to Force users: Jedi Consular, Jedi Knight, Sith Warrior, and Sith Inquisitor. For crafting skills, we recommend using Artifice or Synthweaving for simple synergies. Other crafting skills don't benefit much from stones and artifacts.
BioanalysisThis skill revolves around biosphere analysis. Unlike archeology, bioanalysis does not work with organic, but yet artificial discoveries. The development of bioassays allows players to collect materials from the corpses of plants and creatures. Naturally, this ability works very well in combination with Biochem.
sweepLegendary Need for Speed: Anyone who has played Underground 2 needs to know what a scavenger is. A scavenger is someone who collects valuable trash from common trash, that is, ship wreckage and other damaged technology. However, in SWTOR, the crap that can be found throughout the galaxy is a bit more valuable than, for example, cans and copper wire. Trash cans are the main source of metal products for players.
