Sans and Sayori are good to go for Arcane Hacking! Sayori will use bardic inspiration on Sans and KV before they start this process to pump everyone up. Sans brings to the table previous experience in messing with Lucas's stuff--he has done a lot of tinkering with his liveriverer and he also successfully hacked into Lucas's lab back in Vista Virs. Both he and Sayori will use arcane hacking alongside KV!
