Further we also see new weapons (acid-, fire- and poison-'grenades' etc.), feats, skills and a completely new addition: five prestige classes (a class which you can take without losing experience points). The feats are the traits like we still know them from Fallout, you chose one and you have it for the rest of your character's life. With more than 30 new feats it will become even more difficult in chosing one because every one of them can come in handy. Only three other skills are present in SoU but again all of them are useful; Appraise will get lots of points from the traders amongst us while the Craft Trap is very amusing and ideal to handle large groups of opponents. Just like the aforementioned skills is Tumble (rolling away to avoid an attack) good to exercise. Then the prestige classes... depending of race (sometimes), alignment, feats and skills you'll get to chose one more than probably. As Arcane Archer you can enchant arrows, the Assassin honors his/her name with the Death Attack and invisibility spells, the Blackguard is the best prestige class an evil fighter can get, the Harper Scout is more for the all-round player and Shadow Dancers are masters in disguising themselves.​
