Catalyst
Over 15 years of RuneScape private server experience sits behind Catalyst, a polished custom OSRS build. Unique weapons and armour fill out the gear list, and the bosses are made for this server rather than lifted straight from OSRS. Progression is built to pay back the grind as accounts climb.
