@Kaarme @Dabaha It was a huge coincidence yes. But seeing to what degree his left side was already fcked up (he is kinda missing a few ribs and huge chunk of meat there, has no arm aswell), i am a bit doubtful about that sword actually dealing any meaningful damage in that moment. It probably didnt even had any force on the impact that could help him fall (it is a sword, i believe it's meant to be thrusted with the least force needed). So all that sword did is probably distract him for like a second because it was "ouch", but since there was no critical actions taken at that time, i doubt that it made any difference either.
If the sword hit his hearth there tho, oh boy that would be a Fat piece of plot armor (but i dont think it did).
