Dantarion (of SFV hitbox, Kenbot and more) has released a tool that takes all the scripts that makes up character data and converts it into hitboxes. Keep in mind that this is directly from the character scripts themselves, so some data may be hard to read, but the data is all there. He also promises similar data for Xrd-R and P4AU in the future!
Noted and changed my original post, health regen prevented me from noticing the supplemental damage ' x'
However it comes with a fair wealth of risk since you need the hitbox (which still doesn't gain any invulerability) to hit, you still need to apply both buffs before hand, you lose the wealth of options the buffs provide, and the fact that the DOT is dependent on your proximity to the opponent (the further away you get, the weaker the effect, and the maximum range is less than half of starting neutral).
But it does look like you are safe enough to reapply a buff after it hits, so maybe . . . *grin*
it's not for nothing
if you land 22c with your sword and shield both buffed, it consumes those buffs and applies a burning DoT that does like 1400 (or something, pretty sure it's like 1k+) across its duration
