That demo setup is incorrect I’m afraid.
Let’s see.
Assuming nf which is bis
Demonbolt precast>Soul Rot>G:FG>Vilefiend>build to 5 shards>Dogs>5 shards>hand>3 shards> hand> tyrant> buff trinkets/racial>standard rotation
You look NL but with the standard build you wouldn’t be much different. Slot DeciBolt in in place of soul rot.
