The strength of Eldritch, the Lord of Cinder, is uncertain.
Normally, a Lord of Cinder's power would be greatly diminished after having burned in the First Flame, but there's a huge variable here: the Deeper One-Saint Eldritch consumed Shadow Sun-Gwendolin. This leads to two possibilities. The first is that Eldritch has already digested Shadow Sun-Gwendolin, which is the worst-case scenario. A Lord of Cinder known for devouring humans, if he has digested Gwyn's heir, would almost certainly have a huge power surge.
The second possibility is that Eldritch has consumed Gwendolin but hasn't fully digested him.
This scenario is most favorable for Su Ziyu.
Because during this time Eldritch is still in a 'feeding digestion' state, making it significantly easier to deal with him.
