Rabbit & Steel Solo Lunar Dancer [14:47:0910] [World Record]

Can't believe this happened to me. The loot and upgrade luck was really good. (But I think it could still be better. Don't know if my theory is correct, tho)
Below is me trying to explain how good this run was. I don't know that deep about this game, so I may be wrong, and if you don't know about Rabbit & Steel, it won't make much sense to you anyway, so you can skip it.
Of course the timespace dagger, sapphire secondary, and emerald special are the key upgrades, but I think black strike and queen's crown helped a lot, too.
I don't think secondary burn wasn't as dramatic DPS gain as other loot, but my crude math says it was somewhere between 6~12 % DPS gain. Probably something like 8% expected, or something like that.
And another crude math I did some time ago involved garnet defensive, and while I don't remember the exact numbers, I think it was slight DPS increase over regular defensive, given that they activate the same amount and give same amount of buff time. But the gap should widen quite a bit with sapphire secondary and queen's crown. I was so happy seeing it on the last shop.
I almost died on Karsi, the 3rd dragon boss. I was thinking I should have bought the full heal from the shop. I basically forgot I wasn't at full health. The thoughts the run could have ended there, and I wouldn't have known how good it would have been makes me shiver.
