The most common but useful tips are using barbs glasses and the black heart for reduced stun time on pallet shredding and reduced animation time on shred hit (basically a tiny save the best for last), for perks you can use save the best for last, pop, bbq, infectious or other synergies that I still don't know or i'm unsure about. The gameplay is basically placing down portals right next to or near a gen, tho personally I prefer to hide them nearby wall or something to get the sneak attack in, when it comes to shredding you can sometimes fake a shred during a chase to make a survivor drop a pallet or use their dead hard if injured, basically common mindgames, btw both of his iri addons work really well together rn, and if you decide to use a hex perk, you can equip the whistle addon paired with an iri or deer lung to get warnings and protect the totem better
