So a valid result would likely be: 

Iolanthe takes a slice to her forearm, cutting a bit in to her bracer.

Sigurd takes a slice to one of his legs, which would be immediately cauterized.

EDIT: Before any edits need to be made IC, or a final conclusion is met, I'd like a few last questions clarified.

1. What will have happened to Iolanthe's shield bash? Where do you imagine it's location? From how I saw it, she was covering herself from the sword blow, whilst simultaneously trying to thrust Sigurd's forearm-sword guard region away. Mentioning there might be a clash of steel where Iolanthe's shield might meet the guard or fuller base of his sword means I'm imagining their positioning different than everyone else.

2. Iolanthe's has inhuman leg strength, meaning her pivot should be a lot faster than we're imagining a normal woman is capable of. Regardless of her giant freaking spear, would this be enough to save her forearm?

3. How heavy do you imagine Hyperion is? This is a mistake on my part not to mention its weight in the initial profile, however I did not imagine it being as heavy as a steel weapon of that size would be. Originally I had it in my mind that the lance would be about 15lbs max.
