If you get him just below half per down (assuming you actually mean per sword, but either way this stands true) wouldn't this be the outcome? Leaving me questioning why you need any help besides maybe a math tutor that tells you that 2 halves equal a whole...(just joking I had to put that, I actually am not meaning this in any negative or offensive type of way) [i][b]One sword[/b][/i] = Just below half health [b][i]Two sword [/i][/b]= Just a bit more than dead [b][i]Advanced explanation[/i][/b]: On the first sword Crota would have approx. 47.69% health..If Sword "#2" were to duplicate the first swords damage output, that would leave Crota to have approx. -4.62% health. [i][b]Conclusion[/b][/i]: You would be able to kill Crota in two swords placing myself in envy of you due to your ability to take him down in 2 swords on hard only downing him twice per sword. [b][i]P.S[/i][/b]. If the ending health approximation of "-4.62" doesn't mathematically (see what I did there --->...) "add up" ( ;] but really is subtracting or dividing, no pun intended there ((if that even is a pun, not good with those))..) then please don't bash on my joke about the tutor, never said I didn't need one..
