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.

Does an Artificer’s Magic Item Savant and a multiclassed Thief Rogue’s Use Magic Device allow them to benefit from a Rod of the Pact Keeper?

The Artificer’s Magic Item Savant feature states the following:

At 14th level, your skill with magic items deepens more:
• You can attune to up to five magic items at once.
• You ignore all class, race, spell, and level requirements on attuning to or using a magic item.

The Thief Rogue’s Use Magic Device feature states the following:

By 13th level, you have learned enough about the workings of magic that you can improvise the use of items even when they are not intended for you. You ignore all class, race, and level requirements on the use of magic items.

Rod of the Pact Keeper states the following:

While holding this rod, you gain a +1 bonus to spell attack rolls and to the saving throw DCs of your warlock spells.

In addition, you can regain one warlock spell slot as an action while holding the rod. You can’t use this property again until you finish a long rest.

Since these features allow an Artificer or a multiclassed Thief Rogue to ignore “class” requirements when using a Rod of the Pact Keeper, would they ignore all instances of “Warlock” in the text and benefit from the general bonus to spell attack rolls and saving throw DCs, and be able to regain one spell slot?

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?

Eyes of the Rune Keeper – Extra line of text being quoted?

I signed up specifically to ask this question, because this website is one of the only places I have found this extra line of text in the “Eyes of the Rune Keeper” Warlock invocation from DnD 5e.

On a few posts here I have seen Eyes of the Rune Keeper quoted as:

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

Specifically here: Can Warlock's Eyes of the Rune Keeper decipher written code? and here: What would a Warlock understand from written spells outside of their class, via Eyes of the Rune Keeper?

I haven’t been able to find this specific description for the invocation in any official documentation; I’ve looked through the PHB, both versions of the released errata for the PHB, XGE (most of the official reference books), scoured through Sage Advice, and I can only find one other non-official reference to the extra line of text over at https://dnd5e.fandom.com/wiki/D%26D_5th_Edition_Wikia

Is there any official reference document that contains the second sentence in the above quote, or is the only official description of the ability:

You can read all writing.

How to include The Crooked’s Crew as a Keeper

I’ve run 4 sessions for a group of friends now, and one of my players picked a Crew for one of their starting moves. They ended up being pretty fun characters for everyone to interact with, but when it comes to any sort of tense situation (particularly combat or exploring dangerous locations), I find it really difficult to manage them and have them do anything. In generally, one of three things happen: they show off what in particular is dangerous about the area; they become damage sponges to take harm instead of the hunters; or they just kind of fade into the background or get lost.

Part of it is that the hunters don’t really give the characters any instructions, or have them serve any sort of role, and I have yet to remember to prompt the players during planning. But the bigger part that I can do something about is that I always forget about them in the rush to push the players to act, or else when I do remember, I don’t want them to take away the spotlight from the hunters.

Another of the players just got an animal companion last session, and so I imagine the problem is only going to get worse from here. So I’m looking for some method to giving (in the more general case) Helper bystanders a meaningful, but not spotlight-stealing, role during tense moments within a session.
