Half Celestial Issue
 

I have a 13 HD Half Celestial horse created. According to the SR and DR, it is calculated correctly for a 13 HD. For spell like abilities, it is only calculated as if a 9 or 10 HD. Any way to add the missing spell like abilities?

Created how? Did you make a new creature with the editor, or is this an NPC Hero?

NPC hero

So, you see Dispel Evil, but not Holy Aura, Holy Word or Hallow?
The SLA's for a Half Celestial appear to be assigned using the Base Creatures HD, and not from added HD.
Try using the adjustment "Racial Hit Dice" to add HD to your base creature and not from the Class tab.

Worked perfectly, thanks.
