Soran grew excited because of the 5000 Slaughter EXP that was credited to him.
He now had more than 10,000 Slaughter EXP. This was enough to raise the levels of his Wizard and Rogue profession at the same time. However, he managed to endure the impulse increasing his level. He didn't need to increase the level of his basic profession since his current abilities were still good enough to deal with the Earth Elementals. Also, it was better to keep the EXP for the more advanced professions in the future.
Furthermore, it was only a matter of time before he would be able to activate an advanced profession. Even if he hadn't met the requirements yet, he was sure that he could reach them easily. Take, for example, the advanced profession, Assassin.
Advancing into Assassin had only three preconditions: 100 Sneak, Murderous Heart (Assassinating 100 targets), and 50 in Alchemy (Toxicology).
