Esma- dex dependent or not

[Namine]

Namin? keeps hearing totally different stories on if Esma works with dex... some said that Esma is a predetermined spell with a specific casting time, irreducible by dex. Some say that it does, but esma is relatively fast on its own to notice (and thus only need around 50-80 dex most of the time.) Some say that on heRO's current svn it does not, but later svn will correct it so it's dex influenced again?

So... what's the truth to Esma on the *current* svn that heRO uses?
