Vincent used the Energy Crystals in his hand to release the other two skills, finding that they all had different levels of improvement.
"But..."
Vincent felt the energy in the Water Attribute Energy Crystal Stone in his hand, his mouth twitching a little, feeling a bit of a sting.
"How come it's used up a tenth of its energy after just a few uses!"
Stopping the experiment, Vincent began to consider other possibilities.
If water attribute skills can be released with Water Attribute Energy Crystal Stones, can other skills also be assisted by corresponding attribute Energy Crystals?
Can they be used if they are not the corresponding attribute Energy Crystals?
So Vincent tried again, using Earth Attribute Energy Crystals to release [Water Flow Armor], finding that the defense power of the skill was the same as before, but the energy consumed came from the Energy Crystal, not from within him.
