Dealing with Ethereals was one thing, but fighting fortified illusions which were capable of splitting into two upon being destroyed, presented a whole new challenge. Being a stranger to the Soulscape, Xander had little knowledge about how things worked in this realm, and his wily opponent made sure to take advantage of it.
With the first two attempts to shoot the jugglers failing miserably, Xander decided to try a different approach. He quickly holstered his revolver and conjured his enchanted scythe.
Xander had a hunch that these new illusions weren't entirely invincible but had specific vulnerabilities. It was well within reason to assume that projectile attacks triggered their ability to split in two. However, there was a good chance that a bladed weapon could negate this entirely and finish them in one cleaving strike.
