Floor One: A pack of stone golems. Owen tore through them with [Dragon's Breath] and [Piercing Dive].
Floor Two: Shadow wraiths that phased through physical attacks. Owen learned to infuse his claws with mana, making them tangible enough to strike spiritual entities.
Floor Three: A massive troll with regeneration. Owen used [Shockwave] to keep it off balance, then incinerated it completely, giving it no chance to heal.
