Passive interposed defenses 32

This defensive system consists of burned out aeon stones passively orbiting the ship to intercept meteorites. A more advanced, active version uses iridescent trillian aeon stones (Starfinder Adventure Path #8: Escape from the Prison Moon 44), which congregate around vulnerable ship systems.
Interposed defenses grant a starship temporary Hull Points. These temporary points don’t need to be distributed into quadrants, instead providing a single pool to draw from regardless of which arc an attack strikes. When a starship would take damage to its Hull Points, it first reduces its temporary Hull Points from interposed defenses. Once these temporary Hull Points are reduced to 0, any further damage not absorbed by shields is applied to the starship’s Hull Points. The loss of temporary Hull Points doesn’t count toward the starship’s critical threshold, though for all other effects, any attack that reduces a starship’s temporary Hull Points is treated as though it had dealt Hull Point damage to the target.
Once expended, interposed defenses can be restored only when the starship undergoes repairs, at the same rate and cost as standard Hull Points but requiring a successful Mysticism check in place of the normal Engineering check.
