Then rhythm guitar plays F Sharp minor while the intro guitar keeps playing.

-9--
-10-
-11-  (F sharp minor)
-11-
-9--
-0--

Then chords change to: F Sharp minor, E major, D major, A major.
While this riff plays.

------9-11-9-----------------------------9-11-9--------------|
---11--------11-9-7-9-7---7-----------11--------11-9-7-9-7---|
-9----------------------9---7-9-----9------------------------|
-------------------------------------------------------------|

Then it's the same chords all the way through the song.
When the drop comes in at 1:33 then just strum the F Sharp minor repeatedly again.
Then when the other guitar riff comes in then go back to the F Sharp minor, E major, D 
major, A major.
Nic plays the other guitar riff so unfortunately i don't know exactly what he plays.

Radical fantastical
