A Warlock Pact with the Raven Queen not only grants me a Sentinel Raven, but also the handy ability to see through its eyes. Unlike the telepathic connection with a regular familiar, I don't have to use an action to do so.
If I am blinded, but my Sentinel Raven is not (and within telepathic range), can I use my raven's sight to cast spells that require me to see my target?
Would this negate any disadvantage resulting from me being blinded? Or would I still suffer disadvantage, for example, because I have to cast from my raven's perspective and not my own point of view?
