The alternate version of Separation and Unity that may be the Dreadful Foe of the 3rd floor especially when the player's Light is below 100, Two Forms, One Heart is, for all intents and purposes, identical to Separation and Unity, but the Tidelinked Archon is switched by the Tidelinked Immortal which sacrifices its HP and ATK for increased movement and attack speeds, and recovering from coma twice as fast. This makes the Tidelinked duo trickier to deal with, as the Immortal's faster attack and speed, and recovery can catch the player off-guard.
