It seems that if you do not have Blood Strike active whatsoever, and take damage exceeding 200, you will gain Blood Strike = (damage/2), even if it bypasses the 100 capped limit on it.

I've helped test this further, we managed to get uncapped heals of 1000+ through the use of nonlethal eventmin tool damage. So practically, the cap only applies if the LV is above 0.

This will be fixed in 2.83.
