Newbie Guide HoS Deep Sequence + what happened behind the scene

Helloooooo there! Today we have Herrscher of Sentience in this video series. This video focuses on this Valkyrie Burst mode (in Ultimate) Combo Attack to win this run. I record this run in version 8.7 which is anniversary version in SEA server. The enemy in Elysian Realm Deep Sequence is a lot weaker thanks to special effect it have in this anniversary so I can do this run in Corruption difficulty(the second highest difficulty). If you try this run in future version I recommend to just play in Inferno difficulty just to unlock the valkyrie stamps. Playing in Abstinence difficulty will be challenging with the same equipments I use in this run but I think still possible. If you want to do it in Abstinence difficulty change the Michelangelo T and M stigmatas with Dirac T and M so your HoS will be a lot stronger than mine in this video. I always I hope this video is helpful I am sorry if I speak wrong in english, I am not native english speaker I wish you have good days mate :) 00:00 Intro 00:22 Context 01:20 Preparation 03:49 Strategy 16:00 Last Boss battle 19:23 Conclusion 19:52 What happened behind the scene 21:42 ???
