◈Perpetual Mechanical Array◈ 2 achievements (Total: 20 primogems)

-Massive thank you to DaemonTamer for telling me about this achievement!-
4 types of Ruin Sentinels:
Scout, Defender, Destroyer and Cruiser
✶Each time the Ruin Sentinels are summoned, only one will have a HP bar (as the 'Enhanced Ruin Sentinel'), meaning the other 3 can't take damage (although the one with the HP bar will change each time they're summoned).
✶However, you can still paralyze all of them by hitting them repeatedly, or by using Elemental reactions.

✶Their weak spot is their eyes (similar to Ruin Guards).

✶If you're struggling to paralyze them, focus on using Elemental Bursts instead.
Achievement will issue after defeating the Perpetual Mechanical Array.


✶Instead of fighting, continue to dodge and run until the Perpetual Mechanical Array recalls the Ruin Sentinels.

✶The period of time when the Ruin Sentinels are summoned to when they disappear each time is very long, so bring a healer and a character who can create a shield to avoid further damage (approxiamately 2 minutes).

✶Only attack when the Perpetual Mechanical Array recalls the Ruin Sentinels and can now take damage again.
Achievement will issue after defeating the Perpetual Mechanical Array
