I learned a strange new fact today, Vanish is no longer used for invisibility. The CT has gone out and given every mob (or at least the ones in DS) the ability to see past assassins tricks. This is an outrage! Vanish is an invisibility spell, not just some spell we use just for an 80% damage buff and a quick dash. On the plus side we do get mana regen during vanish. Here's an unedited video with about 3 pixels (give or take 7) showcasing the issue To compensate for this nerf, assassins spin attack should have its damage increased to 300% I know the CT probably didn't do this on purpose. I've already made a bug report but this is kinda important to stop people from expecting vanish to work properly.
