That is… completely irrelevant. Not saying you’re wrong but correcting something so minuscule doesn’t add anything to the topic at hand.
That slow is completely over the top and it should either be nerfed or removed completely. Given how fast that void travels even if you port it it should never have such a slow build in it.
You’re being stupid. The person below you linked the spell and it is clearly written shadow.
Tell me, were you lying on purpose, unable to read a simple wen page, or unable to find the correct spell ? It has to be one of the three, and yet you still decided to press the enter key.
Frightening.
5/7 stupidity
Also, you can test things in game if you ever doubt before being annoying and wrong on a place of public discussion. Does Cloak remove it ? Yes. So it isn’t physical. Does BoP prevent it ? No. So it is not physical. And so on and so forth.
