Quick Fix (Engineering Phase)
If you have at least 12 ranks in Engineering, you can try to repair a system quickly by spending 1 Resolve Point and attempting an Engineering check (DC = 20 + 1-1/2 × your starship’s tier). If successful, you remove the critical damage condition from one system for 1 hour (allowing it to function as if it had taken no critical damage), after which time it must be repaired as normal.
