Homebrew Feat: Familiar Guidance
I’m not actually sure if this is worth or would need a feat, but, for reasons, I was looking at the feasibility of using a familiar as a rather more literal seeing-eye animal? For a blind or deaf PC, or a PC who doesn’t have darkvision, for example. And you can use the familiar’s senses as part of the spell itself, it’s just a little clumsy long-term:
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.
An action and it only lasts a turn. So. A feat to make that a little more feasible longterm? For if you do want to play a blind character with a little mouse familiar that sits on their head, or an owl that sits on their shoulder, and lets them use its eyes as their own pretty much continuously.
(I realise this might be slightly overpowered on, say, a bat familiar, giving 60ft blindsight, or even the owl giving essentially superior darkvision, but … that might be worth spending a feat? Also, I’ve put it so you have to be touching the familiar for this to work, so while you’re using them as eyes they can’t do a lot else)
FEAT: FAMILIAR GUIDANCE
You gain the companionship of a familiar, with whom you have a special supportive bond. When you take this feat, you gain the following benefits:
You learn the Find Familiar spell, which you can cast only as a ritual.
If your familiar takes damage while they are within 100ft of you, you can use your reaction to take that damage yourself instead.
While you are in physical contact with your familiar, you can use their senses as if they were your own, without requiring an action. While sharing your familiar’s senses in this way, you gain the benefits of any special senses the familiar has, and you are blind and deaf with regard to your own senses. As your familiar is sharing your space, you can use their senses for any action, such as casting a spell or attacking, that would require your own.
