Shields = 50%-100% - can do anything with the POS.
Shields = below 50% - can no longer add strontium or online CPU-requiring modules.
Shields = 25% - POS goes into reinforced mode.
Reinforced mode:
- The tower remains in stasis (invulnerable) for a time equal to the amount of strontium clathrates it has.
- No CPU is produced, so all CPU-requiring modules turn off.
- The tower cannot accept fuel, and uses twice as much of the non-strontium fuels per hour as normal.
As attacks normally occur at the enemy's peak online time, you should have enough strontium clathrates to run in reinforced mode for a long enough time that ends nowhere near the enemy's peak time, ie. 12 or 36 hours of strontium clathrates are ideal.
Procedure for POS defense at end of reinforced mode:
- Refuel with more strontium clathrates
- Get as many pilots in remote shield repping ospreys as possible to rep the shield to 50%.
- Remote rep armor and hull of any of your POS structures that are offlined by an attack, and online them again.
- Finish repping the shield to 100%
