I personally enjoy the thick heavy riff used in this song, so I decided to figure it out and well, here it is. Have fun.

Dropped D 1/2 step: Db Ab Db Gb Bb eb

The riff 'hangs' on the 3 fret before it is completed. Listen to the song to get it right on the timing.

Db---2-2-3-2-2---5-6-5-5-4           -5-6-5-5-7
Ab---2-2-3-2-2---5-6-5-5-4   then  -5-6-5-5-7
Db---2-2-3-2-2---5-6-5-5-4           -5-6-5-5-7

"Lied to me, is she not right"

Db-0-0-0
Ab-0-0-0    repeatedly
Db-0-0-0

then

Db-2-2-3-2
Ab-2-2-3-2       let fade
Db-2-2-3-2

eb-------------12
Bb------------
Gb------------
Db---------0
Ab---------0
Db---------0
 

Db-2---3-3-2
Ab-2---3-3-2     repeat
Db-2---3-3-2

thats basically all just listen to the song and youll pick it right up.
