Velocity 51 on green is 58 on blue and wiki
 

Velocity dropped off a mob that only drops 55+ spells. Having had a mage on blue, I knew it was 58 as wiki shows. The spell says 51 on it and a guild mage said he has scribed it pre-58. I don't remember this being a spell that changed, especially not 7 levels added.

Probably another spell that changed from Kunark beta to Kunark launch. Devs have a full list of these and will probably fix them all in one go.

For a long time the only Kunark era spdat was the Kunark beta one off the Kunark cd. There are many more available now and this should be fixed eventually
