Spoiler, caution if not up to playing as Alex___


Hey guys...i had to come back! I need some help in ED. K, i am at the last chapter i think, and i am playing as Alex. I am activating all of the runes and i cant figure out what to do for one of them. It is one of the power runes, when you go into it, there is three pedestals, on of each colour (red, blue, green), when you damage one, the other two send power from them and a horror appears that i have to fight. I have tried everythin and i cant figure out whta to do. Help please!
