Bloodborne: How to Kill Mother Brain, Get Moon Rune and Blood Rock

Mother Brain is an enemy in Bloodborne that will frenzy and kill you if you go anywhere near it. The bad part is there’s a Blood Rock near it which you can use to get any weapon to +10.

It is really easy to kill it though and get the Blood Rock and the video below shows what exactly you need to do. There’s only 1 Blood Rock available in each playthrough so it would be wise not to miss it.

You can also get a Moon rune which gives 30% Blood Echoes from enemies after you do the ‘Make Contact’ gesture for 30-40 seconds.

Once you get a weapon to +10 you will get the weapon master trophy as well.
