I am a unchained summoner who has been allowed to take the Synthesist archetype from summoner. I took the Inevitable sub-type.
At 4th level I become immune to fatigue and exhaustion. At 12th level I become immune to sleep. With being immune to fatigue, exhaustion, and sleep, while fused/melded with the Eidolon, do I need to "sleep" (as in pass out and not pay attention to the world)?
I understand that I need to rest for 8 hours still to prepare my unchained summoner spells, but could I keep watch for the entire night and thus give the rest of the party their sleep.
The rules for rest are located here (some scrolling required).
