Bloodborne - Shadow of Yharnam - Slow and steady

Kill in order from top down. First, kill the non-fire user. Take it slow, run around the map and do slams (poke and run). They will transform when he has about 1/3 health left, so be careful. Once he is down, start taking down the flame-sprayer guy (poke and run), leaving the fireball shooter for last. When flame-sprayer guy is almost dead, use fire-paper. Once you take down flame-sprayer, switch to fast attack speed weapon and go hams on fireball shooter guy. Keep him stunned so he doesn't summon snake.
