The tuning is DADFAD, or open D minor. 

Intro 

D|--12--3----5--3---------12--3----5--3-----------|--------------------------| 
A|--------5--------5p3h5-----------------5p3h5----|--------------------------| 
F|------------------------------------------------|--------------------------| 
D|------------------------------------------------|--------------------------| 
A|------------------------------------------------|--------------------------| 
D|------------------------------------------------|--------------------------| 

Play this twice, than Hozier ads the D6 D4 bassline to the intro riff, it's tricky but possible to learn. 
I'm in the process of learning it right now, so I should update the tab in some time.
