Just trying to get better at him
Rat liver which is a common (grey) add in helps a ton for the shred, because your movement speed will only be reduced to survivor sprint while charging.
other then that, there are good YouTube Videos on how to learn it.
the teachable perks are underwhelming, I think Demo is somewhat good at defending Hex totems with the portals...
If you have save the best for last, you should run it on him, trust me!
You can just shred the obsession and not lose tokens :D
Oh, and a little portal tip, try to hide them from survivors, so they waste a little more time finding them.
Thanks guys, appreciate it!
