Does a Sea Hag’s Death Glare work on a creature that is averting its eyes?

The Sea Hag has a special action called Death Glare:

Death Glare. The hag targets one frightened creature she can see within 30 ft. of her. If the target can see the hag, it must succeed on a DC 11 Wisdom saving throw against this magic or drop to 0 hit points.

Does this work on a target that is averting its eyes?

Does the shadow sorcerer Eyes of the Dark feature negate sunlight sensitivity for creatures like drow in 5e?

The shadow sorcerer feature at 1st level known as Eyes of the Dark reads: From 1st level, you have darkvision with a range of 120 feet.

I would like to play a Drow character, does this negate sunlight sensitivity since you are getting superior darkvision from a new source that does not provide sunlight sensitivity?

I have heard that the warlock’s Devil’s sight provides a similar effect that negates sunlight sensitvity, would this also apply to the shadow sorcerer?

Must I have seen a Flower with my own eyes to use Staff Of Flowers?

I’ve said this before but The Staff Of Flowers from Xgte is a surprisingly useful item for it’s level.

But what I want to know is does the staff require me to know a flower, or just know of a flower? Specifically I want to know exactly how much knowledge of a flower is reasonable to grow it. Does one need to know the name? How it looks? Where it grows? How it can be used? All of the above?

Does one even need to know it’s a flower to make it grow? If a character has never seen Sugar Cane and hears the name and they want to know if it’s a flower or not, can they grow it? What if they know everything else about the plant except that it’s a flower and they want to confirm it?

Does Eyes of the Rune Keeper allow a Warlock to cast other classes’ spells from Scrolls?

The rules for Spell Scrolls state that:

If the spell is on your class’s spell list, you can read the scroll and cast its spell without providing any material components. Otherwise, the scroll is unintelligible.

However, the description of the warlock’s Eyes of the Rune Keeper eldritch invocation (PHB p. 111) states:

You can read all writing.

Therefore, the writing wouldn’t be unintelligible to the warlock (because the warlock can read it). Thus, if a warlock were to be able to perform any verbal or somatic components for a spell on a spell scroll, could they cast it even if it wasn’t on the warlock spell list?

What would a Warlock understand from written spells outside of their class, via Eyes of the Rune Keeper?

This related question asks if you could transcribe a ritual spell to the warlock book via the Book of Ancient Secrets invocation regardless of spell lists, and the answers were generally “yes, but you can’t tell what the spell is”.

This other one asks if you had the Eyes of the Rune Keeper invocation, “could you cast a scroll of a spell outside of your spell list?”, and the answer, using a quote from Crawford, was that you cannot cast the spell since it was out of your spell list (but it did not state if you could actually read the scroll).

By this point, you can probably guess where I’m getting at.

The description of the Warlock eldritch invocation, Eyes of the Rune Keeper:

You can read all writing. You can comprehend any written word or symbol, should it hold any linguistic meaning.

The rules on scrolls outside of your spell list:

If the spell is on your class’s spell list, you can read the scroll and cast its spell without providing any material Components. Otherwise, the scroll is unintelligible.

Can I understand magical literature that is normally outside of my class list if I have the Eyes of the Rune Keeper?

What would I be able to identify from a written spell with Eyes of the Rune Keeper?

Note: I am not asking if I can cast spells outside of my class with the invocation; I am asking if I can understand the nature of the scroll/spell, even if I can’t cast from it.

Perception checks through a familiar’s eyes

If I cast the find familiar spell and summon a familiar, then I can look through my familiar’s eyes, hear through its ears, and communicate with it telepathically. (It is not a blind or deaf creature. If the question of whether it can understand my thoughts is an issue, then assume I am a warlock and my familiar is an imp.)

I tell the familiar to stop for a moment so I can make an active effort to concentrate on what I see and hear. Therefore, I roll a Perception check.

Do I roll it with the familiar’s perception modifier, or my own modifier? Or one roll for me and one roll for the familiar?

Can Warlock’s Eyes of the Rune Keeper decipher written code?

I have a Warlock in the party, and the party came across a message on a fallen enemy. It was written in draconic, and in code.

The Eyes of the Rune Keeper allows the Warlock to read the draconic, But does Eyes of the Rune Keeper allow the Warlock to decipher the code?

Maybe as a side question, if a note is written with a subtle subtext, much like in the way that Thieves Cant is spoken, does that also count for Eyes of the Rune Keeper?
