Defeat the Flowrunner inside Sonic Miracle to obtain Flow Wave, the ascension material for your Flow Espers!

Flowrunner Boss Strategy
The Flowrunner is such a difficult opponent mainly because of its truly impressive self-healing via Sonic Life, which inflicts damage, and heals significant HP.
An appropriate tactical response may call, for deployment of Espers adept at “Diseased” healing blocks to try to prevent the Flowrunner from accumulating a significant advantage. An alternative could involve Espers with AP blocking abilities.
