2 Answers. Nothing. There is no current rule that spell effects end when a caster is unconscious or dies unless they are specifically concentration spells.
Does the DM control the familiar?
While your familiar is within 100 feet of you, you can communicate with it telepathically. So if the player character is more than 100 feet away and thus unable to command their familiar directly, the DM could take control of the familiar.
Can you feed an unconscious person a goodberry?
In reality, you can induce a swallowing reflex by massaging the throat, which is helpful for feeding something to an unconscious person (or an uncooperative pet, as per personal experience) – that seems like a reasonable thing to be able to do with an action.
Do you know if your familiar dies?
No response tells the character the familiar is out of range, or dead. Two actions allow the character to positively confirm dead-ness. Dismissing the familiar has no range limitation, so the caster can spend an action to dismiss the familiar and a second to recall it.
Can familiars give help action?
A familiar counts as a creature, albeit usually a tiny one, and a creature can take actions during combat. Now while it says under the Find Familiar spell that a familiar can’t attack it can take the other actions available (Dash, Disengage, Dodge, Hide, etc.), one of those actions is the Help action.
When does the DM take control of the caster?
The only distinction is when the caster is unconscious or dead; the spell doesn’t specify that anything in particular happens if this occurs, but it’d be reasonable to assume that the DM takes control of its behavior in that case since it’s an independent creature. Also, from the description of Find Familiar:
Can a familiar be controlled by a player?
If the familiar always obeys the caster’s commands, then in practice the familiar is controlled by the player (if not the player character).
What happens when a familiar dies in Baldur’s gate?
The caster receives half the familiar’s total Hit Points (rounded down) as bonus Hit Points. However, the caster must take care to treat his familiar well, for if the familiar should die, the caster loses the bonus Hit Points and half the familiar’s Hit Points again as damage.
