In Saros, Proficiency is the key metric that governs your weapons' strength and effectiveness. It directly determines the level of each weapon you wield, influencing damage output and other combat stats. Raising your Proficiency is essential for progressing through tougher encounters.
To increase Proficiency, focus on using your weapons consistently in battle. Each successful hit, kill, and special ability usage contributes experience toward the weapon's Proficiency bar. Certain missions and challenges may also grant Proficiency boosts or drop items that accelerate improvement.
Besides weapon levels, Proficiency affects your character's overall combat efficiency. Higher Proficiency unlocks new weapon abilities, reduces cooldowns, and can even grant passive bonuses to related skills. Keep an eye on your Proficiency progress to ensure you're always ready for the next threat.
