dnd 5e – Can a Covenant Warlock's pact in gaseous form have its known attack?

Pact of the Chain Warlocks may allow their loved ones to attack instead of them when they perform the Attack action (focus: mine):

They learn the spell "Finding Familiar" and can use it as a ritual. The spell does not count against your number of known spells. When you cast the spell, you can choose one of the normal shapes for your familiar or one of the following special shapes: imp, pseudodragon, quasit or sprite. In addition, if you perform the Attack action, you can do without one of your own attacks so that your friend can use his or her own reaction to attack.

And the spell "Gasform" says that its target can not attack (again highlight my):

In the form of a misty cloud, the target can not speak or manipulate objects, and objects carried or held in its hand can not be dropped, used, or otherwise interacted with. The target can not attack or cast spells.

My question, then, is whether a pact of the Chain Warlock in gaseous form can have its known attack. The spell does not say that the target can not do the attack, but that it can not attack, and in that case, the sorcerer will not make the attack.

dnd 5e – Does Warlock's eyes allow the Rune-keeper to read Druidic?

Druidic is a language, not a code or a cipher

You speak Druidic, the secret language the druid. You can speak the language and leave hidden messages. You and others who speak this language automatically recognize such a message. Others recognize the presence of the message with a successful examination of DC15 wisdom (perception), but can not decrypt it without magic.

The only reason the news is called hidden and secret is language because people who do not know Druidic find it hard to recognize them and can not decrypt them without magic.

You must pass a check to recognize the writing

[Creatures that don’t know Druidic] Recognize the presence of the message with a successful test of DC15 wisdom (perception), which, however, can not decrypt it without magic.

Since you do not know Druidic, you must pass a check to notice the writing at all. Note that in the above description, spotting and decryption are two different things. As soon as you see it, the rune keeper's eyes enter.

The Rune Keeper's eyes are magical and allow you to read the scriptures

The description for all eldritch calls is:

In your study of the occult tradition, you have located eldritch calls, fragments of forbidden knowledge that force you to a permanent state magical Ability.

The Rune-keeper's eyes, a magical ability to be an eldritchian incantation, says:

You can read everything in writing.

So if you can discover something Druidic, you can read it with the Rune Keeper's eyes.
