The original strength of this Sea Siren was around Tier Five, but after being corrupted, its power declined severely, still resembling Tier Four.
However, due to the suppression from the ruins, its strength could only be exerted to below Tier Four levels, and over time, its true strength became infinitely close to Tier Four.
Or rather, even weaker than close to Tier Four.
But even so, it's not something that four Tier Two individuals could defeat.
A Mage and Demon that reach Tier Four are equivalent to entering the second phase, breaking away from the scope of general Mages. With the help of Magic, they even possess the ability to fly for a long time, and the destructive power they can cause is unmatched by Tiers One to Three.
