Thank you. That sounds amazing.The stealth system is similar to Sekiro, so obviously in the trailer you can see the player crouching to do an assasination but beyond that there's a visibility system in place that's also affected by things like ToD and weather. At night and in fog you're going to be harder to detect.
The stealth was one of my favourite aspects of Sekiro and I had hoped it would make its way into Elden Ring. Sounds like they may have done that and more.
No one has said Sekiro combat. It seems to be much more Souls combat than Sekiro.... but with stealth.
