After the battle in Altissa, Ignis becomes permanently blinded. While adjusting to his disability, Ignis remains part of the group and does his best to not be a hindrance.
In Chapter 10: Heart of a King, Gladio and Prompto hang back and assist Ignis through the mines while the player controls Noctis. During this mission Gladio asks Noctis to stay close and not run too far ahead.
In moments I put too much distance between Noctis and the rest of the party, Gladio would get angry and yell at Noctis to come back. I noticed that the more I ran off, the more my teammates seemed to assist Ignis more often and would move slower when I wasn't nearby.
Aside from Gladio sounding angry, is there an actual impact and effect of running ahead and if so, how many times can Noctis run ahead before something happens?
