Bloodborne How to Cheese: Rom the vacuous spider dead in first stage

So this is a bit cheesy but this is how I managed to prevent Rom from teleporting away and commencing his second stage of his boss fight, I just hack and slash delivering as much damage as I can during his next animation and if you’re lucky you can break his animation and stagger him into remaining in his first “less agro” Mode for the rest of the fight :) Bloodborne™
