Based on RAW, each infused pouch will work with any of the other infused pouches within 100 miles of it. Therefore, your interpretation of passing notes like that would not work as you're intending.
That being said, an Artificer could specialize as an Archivist, infuse the pouches, and then at 6th level use Magical Telephony (description below) to ...
Gust of Wind
2nd level evocation
A line of strong wind 60 feet long and 10 feet wide blasts from you in a direction you choose for the spell's Duration. Each creature that starts its turn in the line must succeed on a Strength saving throw or be pushed 15 feet away from you in a direction following the line.
Any creature in the line must spend 2 ...
As written, they do not combine/stack
You can definitely wield two wands, but because of the way the Wand Prototype is written, the +1 effect of an enhanced wand (or wand of the war mage) would not apply.
It's possible that because it's UA they didn't vet the language enough and ended up with a weird wording, but it's also possible that they purposefully ...
I would say the idea of a 'Pokédex-like' mechanic is wrong. You cannot actually accumulate more than one (or two) companion type(s). But there's this part of the rule which leads to confusion in my opinion:
If you use this ability to return a former animal companion to life while you have a current animal companion, your current companion leaves you and ...
The easiest answer completely within the rules as they are, would be to give it an object that you have used your magical tinkering on to allow the homunculus to tap it and play a prerecorded sound or message to alert people within 10 feet of it.
The Lore Master's abilities don't work with spells cast from items
Unfortunately, the Lore Master's Spell Secrets and Alchemical Casting features both have a more restrictive wording than the Sorcerer's metamagic, as they specify the restriction (emphasis mine):
When you cast a spell with a spell slot [...]
If you didn't use a spell slot to cast the ...
Yes, but it's not perfectly smooth
Currently, as described, there are three ways to drop an infusion.
You can die, and wait a few days. This will cause you to drop all of them all at once, and also requires you do die and stay dead for a few days. It's not a perfect solution.
You can infuse enough items to exceed your maximum, thus causing your oldest to ...
As currently written, the only rule for creating a new infusion when you already have your maximum infusions is to automatically drop the oldest, so you can't simply choose to drop any infusion. This may change if/when the Artificer becomes official in a book release as it requires additional bookkeeping to track the order of infusions, and 5E generally ...
As Ryan Thompson has pointed out in his answer, this ability does not specify any limits or other prerequisites other than that your target has "one or more of its allies within 5 feet of it." This means that every turn, you gain advantage against such creatures.
This is in line with a paladin's level 7 feature. Most other paladins gain a passive aura that ...
Cull the Herd applies to every attack as long as the conditions are met
The ability doesn't specify how long the advantage lasts because it doesn't have a duration or a limited number of uses. Each time you make an attack, if the conditions are met at the instant you make the attack, then the ability applies and you have advantage for that attack.
When mounted you have two options. Control the mount (if it will let you) or allow it to act independently.
If controlled, the following applies:
The initiative of a controlled mount changes to match yours when you mount it. It moves
as you direct it, and it has only three action options: Dash,
Disengage, and Dodge.
This restriction applies to ...
Alchemical Mastery (as of the 2019 v2 Artificer UA) states:
When you cast a spell using your alchemist’s supplies as the spellcasting focus, you gain a bonus to one roll of the spell. That roll must restore hit points or be a damage roll that deals acid or poison damage, and the bonus equals your Intelligence modifier (minimum of +1).
Cure wounds is affected by Alchemical Mastery
In general, bonuses stack as long as they are from sources with different names (notable exception for proficiency bonuses):
Different game features can affect a target at the same time. But when two or more game features have the same name, only the effects of one of them—the most potent one—apply while the ...
Let's run through these. All statements are from the perspective of the Ghosts of Saltmarsh Appendix. All statements are sourced from a comparison of the UA Article and the Ghosts of Saltmarsh Appendix A
Action Economy has been Changed
In the UA, on its turn a ship could Move its speed and fire all weapons--or half of its weapons (rounded down) if the ship ...
The rule for Curse of the Sea states:
At 1st level, when you hit a creature with a cantrip's attack or when a creature fails a saving throw against your cantrip, you can curse the target until the end of your next turn or until you curse a different creature.
Once per turn when you cast a spell, you can trigger the curse if that spell deals ...
Happily, this was directly addressed at about 15:00 in the 6/05/2019 Dragon+ Q&A with Jeremy Crawford.
Jeremy Crawford: It says you need to have a free hand to reload a one-handed weapon. Well, it stands to reason that if you don't need to load ammunition, you don't need that free hand to load the nonexistent ammunition. So the short answer is, you ...
Repeating Shot causes the crossbow to ignore the Loading property. Therefore, so can we. The Ammunition property states that you need a free hand to load a single-handed weapon, but Repeating Shot makes clear that deciding to "manually load it" is optional. Thus, if you decide not to manually load it, there is nothing in the Ammunition property that would ...
It is up to you and your DM, but likely it would be controlled.
Iron Defender (UA 11-12):
By 3rd level, the tinkering in your free time has borne you a faithful
companion, an iron defender. This metallic creature resembles a hound,
a cougar, a bear, or another four-legged creature of your choice. It
is friendly to you and your companions, and it ...
