Currently collecting the Guardian blueprints, data and components. I have masses of materials except Guardian technology components which only seem to drop from blowing off destructible panels and you often get power conduits or power cells instead, both of which Sentinels drop. Any idea if there is a better source for these? Also short on obelisk pattern data, particularly delta and epsilon. I understand you can get these from alien ruins. Is there a good site for obelisk scans? Thanks.
