Force faster cast with DEX ?

Simple question, does DEX increase the casting time of Force & WoTg ?

Basic formula states that ALL offensive spells (Sorceries, Pyro,
Miracles) benefit from high DEX in terms of faster cast times but i have
my doubts about Force & WoG.

Is there a video to confirm this ?

Also,
if it indeed does increase the cast time is it possible to do a
backstab after you Force push (force stun) a player with minimum DEX
investment ?

This probably does not have anything to do with faster cast time as it has with (frame) recovery after casting a spell.

Thanks

It indeed does increase the casting speed

Dex does effect casting time, but not for every spell. For instance the gas cloud pyromancy spells (Acid Surge, Poison Mist, Toxic Mist) are unaffected by Dex. I'm pretty sure Force and WoTG cast faster with a higher Dex, but not by much. You can really see the difference between a high and low Dex when casting the various Fireball and Arrow attack spells.
