Tips
The main mechanical differences between this encounter and the other Architect encounters are the acidic water geyser hazards and the moving platforms. Compared to the other three encounters, there’s much less cover here. Tactical Cloak is highly advised if there isn’t sufficient cover and you need to lose target lock from the Architect’s rapid-fire tentacle. This especially applies to the third mount location. The Architect is perched on high ground, so it’s difficult to avoid the onslaught of attacks. You also need to deal with Nullifiers here during the Remnant phases, so the lack of cover becomes even more of an issue because of the Nullifier’s cover-penetrating projectiles. This can be considered the second most difficult Architect encounter, right behind the one on Voeld.
