Figment familiar and preparing or regaining spells?

[Johnny Coleman]

The Eldritch Guardian fighter archetype and the Carnivalist rogue archetype both gain familiars as a wizard of the same level.

What do they do if they take a Figment familiar?

Recurring Dream (Su): A figment has a total number of hit points equal to 1/4 the master’s total hit points. If the figment dies, it vanishes, appearing again with 1 hit point after its master awakens from a full night’s sleep. If a figment ever strays more than 100 feet from its master, a figment enters an antimagic field, or a figment’s master is rendered unconscious or asleep, the figment disappears until the next time its master prepares spells or regains spells per day...

Since neither character archetype has spells to regain or prepare, if they fall unconscious, sleep, or enter an anti-magic field, does their familiar disappear forever?

Could regaining uses of a spell-like ability count for this purpose?

Is it possible to direct your familiar to commit suicide if it ever sees that you are about to sleep or fall unconscious so that it can come back with 1 hit point instead of disappearing forever?

This is one of those times when you have to go with a RAI instead of RAW because archetype interaction messes with the assumption that all familiar classes cast spells. You familiar returns after entering an anti-magic field or whatnot when you wake up from 8 hours of sleep just like if it had died.

This does mean that your fighter or rogue has to get 8 hours of sleep just like a spellcaster in order to get their familiar back.

I think it's safe to assume that it'll come back in the morning even if you can't memorize spells. You'd have to have a really pedantic GM to have it ruled otherwise.
