- Perception checks through a familiar's eyes
- Can I act normally while seeing through my familiar's eyes?
While looking through a familiar's senses, the owner goes blind and deaf. Instead they see and hear what the familiar sees and hears. In some cases, this is even better than the spell caster (blind sense, Devil's Sight, etc).
If the familiar is perched on your shoulder (or pocket, head, or somewhere else on your person), can the owner function normally in all respects, including attacking and casting spells?
As an example, a Tiefling at level 5 I can cast Darkness. Per the spell:
A creature with darkvision can't see through this darkness, and nonmagical light can't illuminate it.
But my imp familiar (Pact of the Chain) has Devil's Sight:
Magical darkness doesn't impede the imp's darkvision.
So if the Tiefling gives over their senses to the imp, they would be able to see normally (or at least to the level of darkvision). Can the warlock now attack the creatures caught in the Darkness spell via sword and/or via spell?
Please do not get hung up on the example
I'm not asking for the best way to see in magical Darkness. The example is just that, an example of using a familiar senses instead of your own in "real time".
For a non-magical example; assume the familiar owner is naturally blind (defect from birth), can they use the familiar's senses to navigate the world, cast spells, and attack evil?
