I figured out the issue. It appears that I was mistaken; my Links entry for Eye Gouge and Boulder Dash were incorrectly formatted.

Here is what I had:
Code
object itemstat "SKILLBOOK_Rogue_Target_EyeGouge","ddbf2d7d-a2b4-4d15-87e2-98653d14964e","SkillbookRogue",0,0,"",1,1,8,0,5,20
object itemstat "SKILLBOOK_Boulder_BoulderDash","10b17363-398f-471d-bfbb-937b3a66ae04","SkillbookEarth",0,0,"",1,1,8,0,2,20


And here is what I needed to have:
Code
object itemstat "SKILLBOOK_Rogue_Target_EyeGouge","ddbf2d7d-a2b4-4d15-87e2-98653d14964e","",0,0,"SkillbookRogue",1,1,8,0,5,20
object itemstat "SKILLBOOK_Boulder_BoulderDash","10b17363-398f-471d-bfbb-937b3a66ae04","",0,0,"SkillbookEarth",1,1,8,0,2,20


Updated version shall be up soon...

Edit:
The link for V2 has been replaced with the updated version. It turns out that my formatting for Invulnerability was wrong as well. All of the skills should be working as intended now.

Edit #2:
Version 1 (without Dust Devil) has been corrected and replaced as well.
