Do caster out of combat options matter?

[Kane0]

Tangentially related, last campaign we discovered that an Amulet of the Planes doesnt have any special requirements on who can attune to it.
Giving it to the Orc Barbarian that rode a 'tamed' wyvern may not have been the best idea...

Edit: and said amulet also has no charges or usage restrictions besides your action and familiarity with the destination, even if you mishap and go to the wrong place!
