green blossom is excellent for this boss fight since you are required to have full stamina to use the stormrulers special attack but it can also save you in close situations where you shouldn't have stamina to roll away charging the attack won't use the stamina so if yhorm charges, stop charging and roll under him if he's cutting it close get some distance if its already charged then give it a swing theres no rush so take your time
Bed of Chaos Pt.2. Just an all around awful boss. IMO should be patched out...?
Yhorm at least is a real boss, unlike that pseudo-puzzle trash known as Bed Of Chaos
