Saros uses a Proficiency system that directly controls your weapon levels and overall combat effectiveness. Boosting Proficiency requires consistent engagement with your gear. The system gates progression behind this mechanic, forcing players to invest time into specific weapons if they want them to scale properly.
Proficiency impacts more than just raw damage numbers. It affects how your weapons handle, their special abilities, and unlock new gameplay options. Players who neglect this system will notice their gear falling behind quickly, especially in higher difficulty content.
The design choice locks meaningful progression behind repetitive use. This creates a grind-heavy experience where you can't simply equip the coolest weapon and move on. You'll need to commit to loadouts over extended play sessions to see returns on investment.
Saros demands intentional build crafting. Casual players should expect slower progression if they like switching weapons frequently. The system rewards specialization over experimentation, which limits flexibility in playstyle throughout early and mid-game sections.
