At the moment experimentals deal out constant damage at death, even if you're at the outer edge of the damage radius. Also, the colossus for instance deals out it's damage from it's feets after it's down on the ground.
I've submitted a change where the damage instead is gradient and also comes from where the actual bones hit something, for instance, the knees of the colossus deal some of the damage, the torso when it hits the ground etc.
Best would be to show it with a video but my gfx card is broken. Some images here (first image is old behavior, second new)

(Note: The actual damage dealt isn't balanced yet so probably less now in total compared to before)
Any input on this proposed change?
