Fixes heretic's ash mark (#64699)

Fixes #63605, meaning ash mark now does 50 stam and 25 burn damage on the first hit, decreasing by 10 stam and 5 burn with each hit, down to a minimum of 10 stam and 5 burn from the 5th hit onwards.

Also makes the bounce target of the mark random, preventing it from getting stuck bouncing between the same two players forever.
