'Well I guess I'm just a badass bitch, because I have a real longsword and you don't, Mr.Thinks girls don't know how swords work.'
'I don't teach anyone, certainly not close combat with swords and spears, which I've admitted in the past to being poor with (due to a complete lack of real world experience.)'
'Also, feel free to look anything I say up, if you find someone disproving me let me know, I'm only running on what I've heard HEMA experts say and what I've read in historical sources. I'm a modern history student predominantly, medieval and ancient histories are a hobby, not my degree.'
'However, I don't really know for certain how it would happen'
'Once again, I don't own swords nor do sword fighting, strictly theoretical.'
Sounds like you're accusing me of sexism and elitism in one sentence, nice.
1. The sword was already on its way out, it glanced off the armour. If it did not glance off the armour, your character would have been injured in some fashion. All armour is designed to deflect momentum, if it had absorbed it your character would be injured, she was not.
2. Your character probably shouldn't have even been able to see Sigurd's movements, as her own shield should be blocking her view. That aside, Sigurd's longsword would be at most a foot under the shield as it dropped. Assuming the sword was somehow so slow it was completely outpaced by the shield, it would still only logically be caught on the way out.
3. You can interpret anything I haven't explicitly stated as you wish, however I've been clear in the way I've launched my attacks, carried out movements and held the shield. You had not. You've simply stated the intent without properly explaining the method. For example, how the shield was held to cover three feet, and how it was subsequently dropped to protect herself.
4. Sigurd is not crouching, he made the slash at her upper thigh as your character dropped, her stance has no bearing on Sigurd. His sword would not touch the ground, he was also striking at a downwards angle anyway so the shield dropping into it would hardly be that counter-active to the move he originally made.
5. If by some immense stroke of luck Sigurd's longsword hit the gladius of dubious location it would make relatively little difference.
6. This is true, but the shin armour would still have an edge to cut through and assorted bindings, all of which can resist the heat effect of your character's spear because her actions should have realistically cut off all momentum from the blow. When talking about fractions of a second I would not expect T3 magic effects to be instantaneously effective. Furthermore, the chance that after Sigurd moved forward Hyperion still managed to make contact in the exact same spot it did before when your character realistically has no fine control over it is ludicrous. Her first attack on the area was woefully ineffective (Pollen ruled it would have very little effect) but it was still more effective than this subsequent attack, where literally no momentum could have been gathered and her arm had just been injured by the longsword. I'm not even sure how your character is still using her giant greatsword at such short range with her shield directly in front of her face, but let's just put it down to magical observation, the ultimate crutch of Arena fighters.
I suppose we'll just have to wait for Pollen's interpretation.
