I pushed a few attacks (without suitable sounds mostly). One of them is Dagger Double Strike, it's a normal single webm. Another is Bone Dagger Attack 4X, it uses the same gfx plus MultiAttack animation.
The thing is, Bone Dagger Attack 4X position is noticeably wrong, even though Ice Dagger Attack3X position with almost the same code is fine. It's probably because MultiAttack uses wrong position for webms.
