With Green99 coming out soon, I believe this is an urgent announcement. "Guise" is not pronounced "goose" or "gweess" or "goo-iss" or anything of the sort. If you're not sure you believe this, just think of the related word "disguise." Don't tell me you say "disgoose." Disgweess? Diss goo iss? Exqueeze me?
The word "guise" refers to the external appearance or semblance of something or someone.
Here is an audio example of someone pronouncing the word correctly.
So...when we see "Guise of the Deceiver" in-game, how do we read it aloud? That's right: "Poopsock fest."
Thank you. Please spread the word.
