Converge - In Her Shadow Chords & Tabs

I have been trying to figure out the chords in this song ever since this album 
came out and oddly enough I was playing a Mastodon song and it sounded similar and 
this is what came of that....

Tuning: DGCFAD

Intro (I'm not tabbing the strumming, listen to the song for that as it changes a 
little throughout the song)
[ Tab from: https://www.guitartabs.cc/tabs/c/converge/in_her_shadow_tab_ver_2.html ]
|-7--7-|         |-0--0-|
|-7--7-|         |-0--0-|
|-7--7-|         |-4--4-|
|-9--9-| x? then |-3--2-|
|-9--9-|         |-4--3-|
|-0--7-|         |------|

Does this through the WHOLE song and in some parts the electric guitar does this little number

|------------------------------|
|------------------------------|
|-7~----11~----7~--------------|
|----9~-----------8~-9~--------|

That's it, hope you likes it
