The key to beating raining blood is simply this
Get the star power at the start of the song before the "Mosh 1" section
And then when mosh 1 comes try as hard as you can untill you drop to yellow and then activate star power and keep trying your ass off
and that should get you through the hard part ... possibly flashing red after it but you'd get through it and the rest of the song is very possible
One
The solo is going up the fret board its
____B_
___Y__
_R____
____B_
___Y__
_R____
____B_
___Y__
_R____
But way faster and then of couse it shifts to Y B and O at the same speed and pattern
And I also learned that the traditional method of HOPO is BULLSHIT
Just try to strum literally every note of the solo while scaling up the 3 notes
Really... now I find 1 very easy and I never even come close to failing I can do it without star power :O
Its solo isnt that hard you just have to realize that you need to strum really fast during it because traditional HOPO methods with 1 strum for 3 of the ntoes are bullshit that dont work
I hope that helps
