OSRS has multiple buyable skills that provide a wide variety of benefits. A lot of these skills will have cheaper or profitable training methods. However, it will take much longer to reach level 99. Rich OSRS players can enjoy the benefit of buying expensive supplies to reach masteries in skills as soon as possible. Herblore: Perhaps the best buyable skill is Herblore because it lets you clean herbs and create potions. Herblore can be an excellent money maker by cleaning herbs. However, most players train the skill to create overloads. They provide huge offensive bonuses, which is ideal for PVM. Prayer: The next top-tier buyable skill is Prayer. Increasing your Prayer level is necessary for PVM and PVP. It gives you access to various protection and offensive bonuses. The most notable prayers are soul split and deflect curses, which are provided after completing The Temple at Senntisten. Smithing: This skill is used to create various armors and weapons. A high Smithing level gives you access to top-tier quests. Also, the skill is used for combining various weapon components.
