As a rule of thumb, having a Town only instinct as the characters default instinct is not ideal- it can only trigger once per town session, which will likely only occur every 3-9 sessions, with the benefit being reducing their Lifestyle cost by 1. It also means they are limited to earning a fate from instinct use, as it can only be beneficial in town.
I had a recent character who was an Enchanter who relied on Manipulator heavily- both for lying and intimidation, usually both at the same time, like convincing Lizardmen he was one of their Gods returned. An instinct I either had or was kicking around at some point was “When meeting some one new, make a new ‘friend’. The advantage of that is it triggers frequently, whenever a new NPC capable and willing to speak enters the scene. Similar ones could be “Always try to intimidate threats”, “Always rely on my force of personality to deal with problems” or “Don’t rely on force when words will suffice”. These also share the advantage of a frequent trigger, as well as the second and third allowing for a few different skills and even demanding or boasting nature to come into play.
