Okay, I understand that when you use Call to Nature, you're given 8 stacks of Natural Power that are consumed when using the Vibrant Health spell, and you're also given a 50% nerf to the damage of your pet and yourself while you have these stacks, while your healing power is buffed by 25%. This debuff lasts for 20 seconds after you use the last Natural Power. That much makes sense to me.
What doesn't make sense to me is this paragraph.
"If under Static Charge, the cooldown duration will be reduced, but the effect will be removed."
What does that mean? There is no cooldown for Call of Nature. And I tried casting it while under the effect of Static Charge and without and didn't notice anything different.
