"Shitty, monster!" Seth cursed and then he jumped and rolled away from where he was as the humanoid threw a large boulder at him. The room was too small for the monster to come in so it tried throwing objects at Seth.
When the initial shock was gone, seth regained his composure and dashed toward the monster as it was grabbing a large rubble, seeing that, the monster dropped the rubble and punched forward, seth slid and avoided the first, while also shortening the staff.
Right when he was beneath the monster, he planted the staff making the upper butt of the staff encounter the monster's face, at the same time the monster's leg rose to stump him like an ant. However, Size Reschedule was faster.
Bang!
As the staff elongated fast, it also expanded its thickness a little and that hit the monster's face very hard and sent it reeling three meters back. Seth didn't use elevated strike for a reason.
