Leon was collecting the blood of the Elves. The blood of high level Elves was a rare and powerful material that could be used to craft a variety of powerful high end items. With the material value of this blood, there was no way that Leon would let it go. The uniqueness of it all made his greed flare.
Naturally, the Elves knew the value of their own blood and when they saw Leon putting away the blood of their fallen comrades, they were enraged!
"Stop him! We must not let him desecrate our fallen comrades!" The declaration was filled with righteous fury and the Elves all let go of their restraints and unleashed their most powerful attacks. Spells and incredibly destructive techniques rained down on Leon's position at once.
Seeing this, Leon's eyes narrowed. He was not shaken by the supposed strength of this joint hail of attacks. He spread open his arms and a pulse of thick magic spread out in a spherical shape, creating a dark purple barrier around himself.
BOOOM!!!!!
