Can you target someone with a “that you can see” spell if you can only see a hand or a foot?

If you just get a glimpse of someone turning a corner, maybe just a foot, can you cast a spell that says "that you can see"? A situation that came up for me was as follows.

Command:

You speak a one-word command to a creature you can see within range. The target must succeed on a Wisdom saving throw or follow the command on its next turn. The spell has no effect if the target is undead, if it doesn’t understand your language, or if your command is directly harmful to it.

A gnome is on my back and I want to cast command to get it to leave. I can only see a hand, but he can hear me. Can I cast command on him? What about skeletons just cresting a sand dune? And can I do a melee attack?

What I’m trying to get at is what it takes to see someone. Do you have to see center mass, a whole body, do they have 3/4 cover if you can only see a hand, even though it is not covered, just behind me?

Is there any way for a Medium PC to wield a 2-handed sword in one hand?

I have a player in my game that has chosen to wield a Greatsword, a 2-handed weapon. As a Fighter, this is within the rules. However, he has asked if he can wield it 1-handed by somehow giving it the Versatile property.

He’s fine having to wield it two-handed if need be for now, but he’s interested in knowing if he can wield it one-handed later. He doesn’t want it for the Duelling or Dual Wielding feats — just “rule of cool” reasons.

RAW, is there any way this can be achieved? Either now, or through character advancement?

Context free languages invariant by “shuffling” right hand side

Given a grammar for a Context Free language $ L$ , we can augment it by "shuffling" the right hand side of each production, e.g.:

$ A \to BCD$ is expanded to $ A \to BCD \; | \; BDC \; | \; CBD \; | CDB \; | \; DBC \; | \; DCB$

It may happen that the resulting language $ L’$ is equal to $ L$

For example:

Source               Shuffled S -> XA | YB         S -> XA | AX | YB | BY A -> YS | SY         A -> YS | SY B -> XS | SX         B -> XS | SX X -> 1               X -> 1 Y -> 0               Y -> 0 

Is there a name for such class of CF languages ($ L = \text{shuffled}(L)$ ?

How to make a handaxe return to my hand after being thrown?

I’m playing D&D 5e and my character is a dwarf fighter. He has two throwable handaxes, and I thought it would be really cool if they could come back to me just after throwing them on someone (like Thor do with Mjolnir). That could be either a boomerang-ish move or some magic (enchantment).

Is there a way to make this possible?

I’m just starting the game as a 1st level character and planning for the future.

Pagination (archive posts) getting out of hand – what to do from an SEO POV?

WordPress as many of us know creates an archive loop of old posts.

From an SEO POV, some of my categories are now at 100+ pages which is a lot of bloat…

Sure, I can set each of these paginated pages a canonical link but still, feels like it is a bit unnecessary for all these indexed pages that just contain a title and an excerpt (which is basically duplicate content..)

Is one approach to simply switch off archive loops or does Google ignore these archived pages?

Thanks

Can I wield Spiritual Weapon in my off hand to mimic two weapon fighting?

Spiritual weapon says:

You create a floating, spectral weapon within range…

…As a bonus action on your turn, you can move the weapon up to 20 feet

This is purely for aesthetics I understand I am actually giving up some of the combat advantage of having a weapon that can move 20′ as a bonus action.
Can I instead wield the spectral weapon in my off hand and otherwise use it as intended? Is there a precedent or rule variant that says so?

The concept of wielding a Shadow Blade and spiritual weapon simultaneously is too cool for me to pass up.

How to delete certain cards that has been used from player hand? [closed]

I am programming the game in Java. I am using Java ArrayList to store the cards. But do a ignore case string check on the cards, the problem is it is deleting the cards with the name "Trooper", but it always leave one trooper card in the player hand. I wanted it to leave all trooper cards.

Card Display in Java Console: Trooper Agent Agent Agent Trooper Trooper

Jave Code:

if(mouseCursor.getRectangle().intersects(placeList.get(i).getRectangle())                         && mouseCursor.isPressed() )                         {                              if(attackPower >= placeList.get(i).getAttackPower())                             {                                 for(int j = 0 ; j < playerDisplayDeck.size();j++)                                 {                                     System.out.println(playerDisplayDeck.get(j).getName());                                 }                                                                  for(int j = 0 ; j < playerDisplayDeck.size();j++)                                 {                                      if(playerDisplayDeck.get(j).getName().equalsIgnoreCase("trooper"))                                     {                                         playerDisplayDeck.remove(j);                                     }                                 }                                                                  for(int j = 0 ; j < playerDisplayDeck.size();j++)                                 {                                     System.out.println(playerDisplayDeck.size());                                 }                                                                  attackPower = attackPower - placeList.get(i).getAttackPower(); }                              

Can Mage Hand drag more weight than it can carry?

I have been watching/listening to Chance’s D&D Spellbook, which highlights a potential ‘loophole’ in that the spell doesn’t list how much the hang can drag, say if attached via a rope that weighs less than 10lbs.

Normally a spell only does what it says, but carrying and dragging seem closely enough related that there might be some room for interpretation.

Wielding two wands in one hand [closed]

So I have a Warlock/Sorceror in my campaign. He just picked up Warcaster to carry a shield. However, he wants to create a nonmagical item(essentially a Chinese finger trap) to hold his hand of the war mage and his wand of fireball without having to use a bonus action to put one away and pull out the new one. I think it’s a bit much, but I’d love some insight from other DMs

Hand crossbows, shortswords, and artificers

Ok, so here is my question. Let’s say you have an artificer that is a battle smith, so he has the extra attack ability. Now let’s say he has a shortsword in one hand, and a hand crossbow which is given the repeating shot infusion; Which specifically ignores the reloading property, and causes it to magically generate ammo to fire. Now, let’s say the artificer takes the attack action, would the artificer be allowed to swing with the shortsword with the first attack, and fire the hand crossbow with the second attack against another enemy? Or must both attacks granted from Extra Attack be made with the same weapon?
