Sentinel Pillars & Corrupted Sentinels

Sentinel Pillars are heavily guarded structures found on planets, often surrounded by Corrupted Sentinels. These pillars are key to temporarily disabling all Sentinels on a planet. To access the pillar's core, you must defeat waves of Corrupted Sentinels, including specialized units like the Sentinel Hardframe and Sentinel Quad. Destroying the pillar's core grants you a Sentinel Multi-tool blueprint, unique upgrade modules, and a period of peace from Sentinel patrols. This is a challenging combat encounter that requires a well-upgraded Multi-tool and good combat tactics.
