There is a ton of incorrect information going out. For the integrity of the guide, I would like to clear things up. First

So basically its... Jolt + VerThunder instantly.

So you literally are casting a 180 potency spell directly in tandem with a 300 potency spell. There's literally no buildup. It's instant. And this is with EVERY spell.... not just that spell.
This is 100% False. Damage is calculated as Damage Per Second. It is not a 480 potency attack. It is a 180 potency attack and 300 potency attack in two GCDs. Only with Dualcast, the second spell is executed at the beginning of the GCD, just like a weaponskill. Its still a GCD and you can't cast another spell in that time period. Regardless of how you try and spin it, it is 100% false. It is two 2.38 GCDs. plain and simple.
