The Archer(弓使い, Yumi Tsukai?) job is available to humes and viera as a basic job in Final Fantasy Tactics Advance. Archers are well-known for their long range combat via bow and arrows wielding. The range of their attack varies depending on what bow they are wielding.
When two Archery abilities are mastered by humans, they can become Hunters. When two Archery abilities are mastered by viera, they can become Snipers. They are also one of two job that can ward off the undead for good, the other being the White Monk.
Hume Archers are almost completely inferior to Soldiers and Thieves, the other two basic physical-damage hume jobs. The only stat that isn't outclassed by either the Soldier or the Thief is the Archer's Resistance, which combined with their long ranged physical damage makes them useful as an anti-mage job early on. Compared to the viera Archer, again the only notably higher stat is Resistance.
Viera Archers are inferior to Fencers, the Archer being only a tenth of a point faster, having slightly better resistance, and having marginally higher MP, while the rest of their stats are noticeably lower. Although viera Archers may seem superior to hume Archers, the fact is that Fencers are even better than either of them. In theory, viera Archers could also be used as an anti-mage job, but the difference in Resistance between the viera Archer and Fencer is negligible.
