Since the Monster knows when Griffin was picked off the bat, intelligent Monsters will sneak away to leave him nothing to go on at the start of matches.
This gives Griffin the legitimate downside of a harder time finding the Monster early in exchange for a theoretically easier time finding him later.
However, if the Monster is intelligent and sneaks to avoid sound spike detection, Griffin is essentially blind to the Monster’s location.
Barring a lucky crossing or Carrion RNG, the Hunters don’t have much to track the Monster in this scenario.
Due to the heavy early game trade-off, I feel that the Monster does not need to be able to avoid Spike detection when in their radius or have the ability to easily detect them.
For these reasons, I suggest that Sound Spikes pick up the Monster no matter what they are doing with no smell for them to pick up on.
