The eyes look absolutely fantastic and even seem to have a slight glow-in-the-dark portion to them.
I'm not a fan.Dark IV and V - More veins, plus glowing red eyes. This looks really well designed during the cutscenes, but during the game graphics (even on High), it looks like their face is simply dirty. No really, that's it.Dark II & III - Increasing amount of dark veins. I did not take pictures, regrettably.I can give you my impression of the corruption though.Dark I - Orange eyes. However, the dirty face thing was just too annoying to me. Not an easy decision, because I really loved the red eyes. The veins at this point however, become too 'dirty' for me to enjoy the sith corruption option anymore.I turned corruption off with Dark IV, personally.
And you're eyes get a brighter red that has a glow to them.All in all it looks like you have a disease by the end!The only exception to the paling skin that I've seen is in cyborgs, they get everything else except the paling skin for whatever reason. Ie, the area around your eyes blackens, and same with around your mouth.Rank 3, you're skin begins to pale, and the darkness around your eyes and mouth expand outward via your veins, like you are being corrupted.Rank 4, you're eyes turn red, your skin pales even more.Rank 5, mega paleness, like you go from red to pink basically if you are say a red twi, or Dark blue to pale white blue if a dark blue twi. Like you see in the movies.Rank 2, eyes are the same, but now you get a zombie look started. It will go from whatever you have to a light yellow glowing eye effect. Rank 1, all that will change will be your eye color. Star Wars The Old Republic Dark Side Corruption 2017
