You are given this saddle if you allow Master Mirror to take Olgierd's soul, and you choose "To be as swift as the wind". Equipping it transforms Roach into a demonic-looking black horse with glowing eyes. According to the description, it also applies a short-range effect, possibly similar to the stagger caused by the Axii ability Delusion.
Associated quest Edit
- ↑ In some cases (known on PS4) it will only be the left eye of Roach that is glowing - not both of them.
