Tyrfing

The Hollow Investigative Association has been studying Tyrfing's behavioral patterns, and research results show that its seemingly unbalanced stance of swaying and skewing is, in fact, a highly efficient stance for launching successive slashing attacks.
Due to its frequent appearances and aggressive behavior, Tyrfing has been identified as one of the most deadly Ethereals in the Hollow, particularly for certain Hollow personnel.
When faced with a shielded enemy, it relentlessly launches attacks until either its enemy or itself is destroyed.
"Perhaps... they don't actually hate us, but just think of us as punching bags for practice?"

During combat, Tyrfing will perform 3 melee attacks in a row, stopping if it lands a hit.
