I saw a few posts from other people mentioning that this Focus Spell should have its duration increased to 10 minutes but wanted to add my playtest feedback for this.
This focus spell really wants to be a out-of-combat spell. It's a pretty natural trope to want your eidolon to scout ahead, especially when they have alternative speeds and senses to use. 1 minute is far too limiting to accomplish this, even if they do have an advantage of unmanifesting at the end so they don't necessarily need to secure a route back to the party.
I wouldn't mind seeing a 10-minute duration as a heightened version of the Focus spell, so that while not being available at Level 1, eventually unlocks as an option to use.
Having the duration become longer than 10 minutes is awkward for a Focus spell, but might still be okay for consideration as another heightened level (like an hour for example) since the Summoner's refocus activity requires bonding with their Eidolon which wouldn't be possible until they returned. (If the Summoner gains another Refocus activity, I can't see this being a broken Focus spell still.)
