Similar to the following:
- Can I act normally while seeing through my familiar's eyes, per the Find Familiar spell?
- Can a spell caster attack and/or cast spells while using a familiar's senses?
Find Familiar has this paragraph:
While your familiar is within 100 feet of you, you can communicate with it telepathically. Additionally, as an action, you can see through your familiar's eyes and hear what it hears until the start of your next turn, gaining the benefits of any special senses that the familiar has. During this time, you are deaf and blind with regard to your own senses.
The Blinded condition is the following:
- A blinded creature can't see and automatically fails any ability check that requires sight.
- Attack rolls against the creature have advantage, and the creature's attack rolls have disadvantage.
So since I am blinded in regard to my own senses would I still suffer attacks having advantage against me or since I can see the attacks coming through my familiar would they attack normally? I'd say it's the latter as there is nothing saying that you can't move while using your familiar's senses. If that were an issue I believe it would be stated in the spell description as spells do what they say they do.
