Hi,
just to publish this: Arcane Blast does not consume Ice flows... You can continuously cast arcane blast and move freely for the 15s it lasts. Only Arcane missiles consumes it.
I already reported this on Beta over a month ago. But as all the betas I played the bugs from EU are not seen....
So I post this here, as I have experienced things will be fixed then really soon. Although I would like to see this stay, as it is really fun
Have fun to freely move as arcane with ice flows and arcane blast.
