Cara Has Been Parried

Karl raced through the darkness, following the sounds of snarling and crashing towards the heated battle. Then skidded to a stop when he saw the situation.

Cara was squared off against a tiny ball of glowing fur, with a large shining rock in its paws.

She cast [Void Blast] and the fur ball surrounded itself with a rock shield, then pelted her with spears of holy light, which she blocked with a barrier of [Disintegrate].

That made the spears explode, and the cavern trembled.

They were attacking multiple times per second, and the whole cavern complex was trembling. 

Karl shaped a [Bulwark] to trap the furry creature, cutting through the stone to put it in a full bubble, and the battle stopped. 

"Cara, what is that?" He demanded.

[It stole my rock.] Cara complained.
