Alien Guard - Purification

SD-type enemies have Embodied and Consolidated forms and start with Embodied form. In this form, if HP reaches a threshold, the enemy will transform into Consolidated form for a fixed duration. In Consolidated form, any DMG taken by the SD-type enemy will directly decrease its max HP. When its max HP has been reduced to a threshold, it will refresh the Consolidated form duration.
When Consolidated form ends, the enemy will return to Embodied form.
Every time the enemy enters Consolidated form, it will recover its HP up to the current max HP. In this form, it also gains additional DMG Reduction.
SD-types enemies die when their HP or max HP drops to 0.
Every time an SD-type enemy's HP reaches a threshold, it will drop multiple Stardust Remnants nearby. Picking up those Stardust Remnants grants Heterogeneous Resonance state, which allows characters to deal more DMG to the enemy's max HP.
[Strategy] Pick up Stardust Remnants to deal additional DMG to the max HP of SD-type enemies.
