Guild Wars 2

I can’t seem to get my healing rain to work, or even cast when i click on it, it does nothing. No yellow bar comes up to show its casting, no green/red circle comes up at all nothing. I’ve tried with another ally targeted and without an ally targeted.

Please get this fixed asap.

Have you made sure that you have unlocked it? I ask because I had this issue as well and then when I killed more it then unlocked. There seems to be an issue with the tooltip not updating saying your unlock progress, so when you mouse over it nothing shows up saying what percentage your progress for unlocking it is. There are a couple of elementalist weapon skills that are like this.

As Lycos mentioned, you need to unlock the skill. I noticed something similar when I first used a Focus and Earth attunement, I never found the need for it before, and I was wondering why the 5th ability didn’t work. After killing 2 mobs, I got the message that it was now available.
Go into a lower level zones and kill some easy mobs with auto attack and just wait for it to become available.

Another thing could be that you somehow enabled ground quick cast or whatever the option is called in English – available via F11. This fires any ground targetted spell at where your mouse is pointing without giving you the aiming circle.
