Does this do anything for me?

"With a flap of his great wings, he leans forward and utters a few magical words. A glowing symbol appears upon your cheek - he has granted you his blessing."

It just gives you a temporary mark on the cheek of your HA.

Is that really all it does :/ I was hopping for some boost or something... LAME!

Unless I've been laboring under a misapprehension all this time. >> Someone can feel free to correct me if I'm wrong, but I'm pretty sure that's all it is. ^^

nope, that's all it does... you do get an achievement the first time it happens, but other than that it's purely cosmetic.
