I don't know what is " Speedrun or Release version" so don't hesitate to tell me if i put the wrong version. The RTA is maybe not exactly calculated but i did it as i can , and i don't know if the RTA starts at the beginning or the end of the animation for the sword, so once again, don't hesitate to tell me. The sword animation finish at 17 sec. on the video and the last hit to the boss is at 8:44 .
