What is it?

Decript Skeleton

You peer in the boss room at the height of the mansion and see the boss, the Decript Skeleton. It's armed with a sword and shield. At a glance, it doesn't have as much HP as you'd expect a boss to have. You cast soul crush and it is suddenly alerted to an enemy presence. You cast illusion and throw the doors open.

Seeing no one in the door way, the boss starts cautiously walking up towards the door to check behind it. Meanwhile, you've walked behind it and began charging your dark orb. It fires off and is a direct hit! It took out about a fourth of the bosses HP.

It then turns around and charges in the direction of the blast waving its sword around. Too bad you already moved behind it. You fire off another dark orb and are rewarded with the resounding blast of a critical hit, leaving its health in the red. It turns around at you and throws down its sword and shield. It's eye sockets begin to glow a blood red as it begins to cast a spell.

You try not to let it finish as you begin to cast a dark orb. But nothing happens.

You glance at your MP and find yourself with none. You forgot about its aura. You quickly check it out.

Soul drain: casts an aura about the field, draining enemy's MP. Once the enemy has no MP remaining, you gain the ability to cast their spells.

Just then, your illusion spell wears off. Just as its is cast.
