It didn't seem like Felix had a solution for the [Mist Veil], and the stalemate would likely continue for quite some time, so Hal took his time and made his own preparations.
He had one shot.
If he failed, he would have to deal with the consequences of allowing his opponent to fully establish himself on the stage.
Hal placed a charge of [Voice Orb] on the northern side of the stage—since he was planning to strike from behind Felix—along with a charge of [Conjure Taunt Puppet].
His adversary would probably be able to escape the trap almost immediately, especially since both spell cards were only level one, so Hal had to execute everything perfectly.
His plan was simple: sneak close to Felix, distract him using the [Voice Orb] and the [Taunt Puppet], take away his vision with a low-range debuff spell, force him to use his repositioning skill poorly, and finish him off with one swift, [Rare]-tier dark elemental spell that fed on any nearby negative emotions to increase its power.
