Astra trap is a strategy pattern derived from documented Riftborne mechanics and should be evaluated against the active world state. Source
Evidence status — Strategy: This page derives recommendations from confirmed mechanics. It does not describe an official guarantee.
Raid Astra shortly before a known garrison burn or incoming reinforcement. The loot may matter less than forcing starvation. Cheapest ships die first, so a screen can evaporate and change the target mix for the next attack.
Counter: several hours of Astra, Drone Facility, emergency shipments, and alerts.
