Esma- dex dependent or not

[Stealth]

well, the database i got the info is online since 2002, the beta phase i guess, but i can look up on other pages, like rocards, the one i trust more, unfortunately, rocards is in deustch, but a good google translation and some mind effort can make us understand easily,

A very strong magic attack, whose element depends on warm wind. The Skill is affected by ?warm wind?. The Aftercastdelay amount is 0,5 seconds. The Cast amount is 2 seconds.

the original text is on the img, maybe someone can translate better than google. and looks like it doesn't say if it is or it isn't reduced by dex.

on the ragnasim, simulator, the dex affects the cast time and the sp cost is *8 instead of *10. and i believe since the rocards doesn't say it is a fixed time, the common sense would say that it is affected by dex.
