There are two Bloodclaw effects the first is a 20 point dd spell and the second is roughly a 80 point damage dot. I know th dot is there because first I tried it out on some low level creatures like Pumas and as they ran they kept losing life I've also managed to kill a few lizzies in Cazic with the bloodclaw effect as they ran for help.
