Corrupted Sentinel Pillars are a more structured combat challenge. To disable the pillar, you must defeat several waves of Corrupted Sentinels, culminating in a fight against a Sentinel Hardframe and multiple Sentinel Quads.
Phase 1: Initial Waves
You'll face standard Corrupted Sentinels and Quads. Use your preferred combat Multi-tool weapon. Keep moving to avoid incoming fire.
Phase 2: Hardframe & Quads
The Sentinel Hardframe is a formidable opponent. It has heavy armor and powerful attacks. Focus fire on its weak points, typically the glowing red joints or its head. Use grenades or the Plasma Launcher for area damage against the accompanying Quads. Maintain distance and use cover. Once the Hardframe is destroyed, finish off any remaining Quads.
Rewards: Sentinel Multi-tool blueprint, unique upgrade modules, temporary Sentinel deactivation.
