Emery was completely amazed to see water spells could be utilized like this. In fact, he didn't once think of or even imagine such applications, before he watched how Trish skillfully showcased her complete mastery over the water element.
What Trish displayed should be a unique water spell, just like Gerri's signature purple flame. However, this Heavy Water - as she had called it - did seem to have other useful functions, other than just hitting harder, like Gerri's flame did.
Seeing the huge wave of such water threatening to crash into him, while his feet were still stuck onto the ground by the very same water, Emery quickly cast his spell to counteract this attack of hers.
[Granite Wall]
[Shadow Roots]
Both spells took effect at once and worked in tandem to block the incoming wave.
