How can I increase my Monk’s unarmed damage?

I’m pretty new to D&D, and I just started an Evil campaign. I am a wood elf, Chaotic Neutral aligned, 3rd level Monk(Open Hand).

Our party has a couple of barbarians, a few rogues, and a trickster.

I realize that fist fighting isn’t going to get a 1d10 or even a 1d8, but 1d4 is pretty useless unless you’re brawling in a bar. If there’s a way I can use a feat or something to get a small bonus (I already have a Dex bonus of +4) I would appreciate it

I have noticed that my damage output is considerably lower than my friends’ damage. We are trying to escape a mining complex. I didn’t notice the damage difference until everyone got better weapons than rocks and pickaxes.

I can make a bonus attack but with only 1d4+4 damge per hit, I do nothing to the guards, who have an ac of 12 and 14 hp.

Does “Magic Weapon, Legion’s” affect the monk’s unarmed strikes as the normal “Magic Weapon” does?

"Magic Weapon, Legion’s", states the following (emphasis mine):

This spell functions like magic weapon (see page 251 of the Player’s Handbook), except as noted above and as follows. It affects only weapons held by allies when the spell is cast. It has no effect on ammunition.

and "Magic Weapon" states the following:

You can’t cast this spell on a natural weapon, such as an unarmed strike (instead, see magic fang). A monk’s unarmed strike is considered a weapon, and thus it can be enhanced by this spell.

Therefore, does the Legion’s version also consider the monk’s unarmed strikes are weapons held or not?

Does a monk’s Unarmored Movement speed increase apply to the fly speed gained from a Fly spell?

A monk’s Unarmored Movement class feature increases the monks speed by 10 feet at level 2, and further at higher levels. According to this Sage Advice, this stacks with an Aarakocra monk’s fly speed, because that fly speed is innate to the race.

However, how does this interact with fly speeds gained from other sources, such as the Fly spell? That spell specifically states that “the target gains a flying speed of 60 feet for the duration.” Can this gained flying speed then be improved by a monk’s Unarmored Movement, giving a level 2 monk a flying speed of 70 feet with the Fly spell cast on them?

What features, items, or spells allow dodging as a bonus action other than Monk’s Patient Defense?

I’m looking for features, spells, or items that trigger Dwarven Fortitude without the use of Ki points.

Dwarven Fortitude:

Whenever you take the Dodge action in combat, you can spend one Hit Die to heal yourself. Roll the die, add your Constitution modifier, and regain a number of hit points equal to the total (minimum of 1).

The feat requires performing the Dodge action. As such, Sword of the Paruns, Blur, Foresight, or any other thing that gives the benefits of the Dodge action would not trigger the feat, as far as I’m aware.

Does a Tortle’s Natural Armor interfere with the Monk’s Unarmored Movement ability?

The Tortle’s Natural Armor ability says:

Due to your shell and the shape of your body, you are ill-suited to wearing armor. Your shell provides ample protection, however; it gives you a base AC of 17 (your Dexterity modifier doesn’t affect this number). You gain no benefit from wearing armor, but if you are using a shield, you can apply the shield’s bonus as normal.

The Monk’s Unarmored Movement ability says:

Starting at 2nd level, your speed increases by 10 feet while you are not wearing armor or wielding a shield. This bonus increases when you reach certain monk levels, as shown in the Monk table.

The comments on this answer to a related question briefly mention the interaction between Natural Armor and Unarmored Movement, but nothing conclusive is discussed.

It is not clear if Natural Armor counts as worn, or even as armor, for the purposes of the Monk’s Unarmored Movement Ability.

Does a Tortle’s Natural Armor interfere with the Monk’s Unarmored Movement ability?

Are monks only allowed to use non-unarmed weapons as off-hand when two-weapon fighting?

Do the special rules regarding monks’ unarmed strikes prevent monks from using unarmed strikes as off-hand weapons when using two-weapon fighting?

The monk class’ unarmed strike section states:

There is no such thing as an off-hand attack for a monk striking unarmed.

The context of this is dealing with 1x vs. 1/2x strength, but as a side effect, does it mean a monk must use a weapon rather than an unarmed strike when using two weapon fighting to generate more attacks per round?

Two-weapon fighting states:

If you wield a second weapon in your off hand, you can get one extra attack per round with that weapon.

It then states later on, confirming that unarmed strikes may normally be used:

(An unarmed strike is always considered light.)

Can you kill a Tarrasque with the Open Hand monk’s Quivering Palm feature?

I see the Tarrasque has Legendary Resistance so it can pass failed saving throws. It has a list of Legendary Actions 3 times a day. I keep seeing people say to keep making it do saves to get rid of the Legendary Resistance even though it is not listed under the limited Legendary actions.

Since the Way of the Open Hand monk’s Quivering Palm technique relies on failing a Constitution save to instantly reduce the target to 0 HP, can Quivering Palm kill a Tarrasque?

Is the “Way of the Astral Self” Monk’s extra punch useless?

Martial arts for monks states that when you take the attack action you can make 1 unarmed strike as a bonus action. However Astral monks at third level says the same thing: “you can make 1 unarmed strike as a bonus action.”

I know at higher levels that increases but I’m asking about only level 3. Because you only get 1 bonus action does that make that extra attack feature from one or the other useless?

Also, flurry of blows makes 2 strikes as a bonus action so if you use that are both these abilities rendered pointless. Finally, at level 11 of astral monk you can make 2 strikes as a bonus action. Would this make flurry of blows a pointless ability? Have I understood this correctly or would all these abilities stack on top of each other?

Can I exclude characters from understanding my magically understandable speech from the monk’s Tongue of the Sun and Moon feature?

The rules for the monk ability Tongue of the Sun and Moon state:

Starting at 13th level, you learn to touch the ki of other minds so that you understand all spoken languages. Moreover, any creature that can understand a language can understand what you say.
PHB, pp.79

The text says that this ability is something you learn to do, not something that simply happens to you, so it’s not necessarily always on. Further, it seems logical to say that this is something you would do actively. That is, you could choose not to touch someone’s mind, thereby excluding them from understanding you. You could also choose not to understand someone yourself, just in case they’re telling the funniest joke in the world, or using a subliminal trigger.

Assuming you can choose not to touch someone’s mind, let’s reason further. Suppose you’re speaking and don’t know that there is someone listening in nearby. Would they understand you, i.e. is the default that you are or aren’t touching someone’s mind? Similarly, if you are speaking to a large group of people, would you have to focus on all of them at once for them to understand you? Would this take effort? Is there a range?

My questions are:

  1. Can you exclude some characters from understanding you while allowing others to do so?
  2. Can you decide not to understand someone who is speaking?

Basically, these boil down to: Can you choose not to touch someone’s mind?

Then, assuming that the answer to the above is yes:

  1. Do you have to know someone is listening in order for them to understand you?
  2. Is there a limit to the number of people you can affect? A range?

I also asked this related question about the mechanism of the ability.
