Graveknight Math

[C_Trigger]

I'm looking at the Graveknight and looking to switch out its weapons to a longsword and shield but I cant figure out the original math for the to hit and damage on the greatsword. My math is as follows

to hit
+10 bab
+1 Greater weapon focus
+1 weapon focus
+1 magic sword
+9 Strength (27 base and +2 belt of Giant strenght)
+2 weapon training (heavy blade)
total=24
but the book has it at 25 anyone know what I am missing?

damage
+13 strength
+1 magic weapon
+2 weapon training
+2 weapon specialization
total= 18
again the book has it at 19 any help I'm a new GM so messing with monsters is new to me. Thanks in advance!

Graveknights exude an aura of evil as a Desecrate spell, which gives +1 profane bonus to atk/dmg among other things

Thanks for the help it was driving me mad.

The stat block doesn't include a belt of giants strength. However, the armor counts as an altar, so desecrate is a +2 attack/damage/saves.
