New runner here and I have watch a few runs as reference before doing actual timed runs. I heard deviljoe at AGDQ2015 mentioning there were setups being discovered (but still unreliable) for the boss battle pikeball glitch in wich you can get very quick kills. I have been searching for this glitch and explanation on how it works but all I've been able to find is Yaria Fu's run and the 2 quick kills achieved with the glitch. Still have no clue how it even works.
