A spell like this has material components that are not consumed. This means that the components can be reused. The components for this spell also do not have a cost indicated, so you can use a spellcasting focus or component pouch instead (these options can also be repeated as long as you have spell slots).

A spell like Identity has a material component with a set cost (a 100gp pearl). This means that the pearl is required and can not be replaced with a spellcasting focus or component pouch. The pearl however is not consumed. This means that as long as you have that pearl, you can cast the spell as much as you want.

Some spells (such as revivify) have components that are consumed when the spell is cast. These components will need to be replaced each time you cast the spell.

Is their a similar spell for warlock

could you cast this spell at higher levels and get more of an arm or body? say using it at a 9th level spell make an upper bust like a susanoo???

1) Can this spell block movement?

2) a Creature can squeeze to try to pass (if it succeeds on the saving throw)

3) Can a creature jump over it?

yes on both accounts at my table, but i'd talk to your DM first

the components aren't consumed

not raw but cool

look up jumping, squeezing, and moving through a creatures space rules

Is it a concentration spell?

If there's one thing I like about this spell, while it cannot replace a spell like web being single (doubled with twinned spell) Against a low strength mage even if they misty step they are still restrained by the hand.

A Medium hand made from compacted soil rises there and reaches for one creature you can see within 5 feet of it. The target must make a Strength saving throw. On a failed save, the target takes 2d6 bludgeoning damage and is restrained for the spell’s duration.

To break out, the restrained target can use its action to make a Strength check against your spell save DC. On a success, the target escapes and is no longer restrained by the hand.

While Web states you are no longer restrained when you leave the area or break out.

Each creature that starts its turn in the webs or that enters them during its turn must make a Dexterity saving throw. On a failed save, the creature is restrained as long as it remains in the webs or until it breaks free.

A creature restrained by the webs can use its action to make a Strength check against your spell save DC. If it succeeds, it is no longer restrained.

So yeah, cast, run, take cover and laugh, as the necromancer gets crushed to death in the next room.

As a necromancer, you can easily reflavor this as a skeletal or zombie hand.  

Fun random thing I've used this spell for: I created a hand shaped chair of stone cause I was bored while the rest of the party knew a language I didnt and were figuring out a puzzle in said language.

I like this spell, but it is kind of a noobtrap. 

The first cast is great and the damage each turn plus restrain is good too, but after that the fact that you can use the action to MOVE the hand will cost many newer players to waste a turn thinking that means you can actually grab something else. 

Its better to just let go of the spell as soon as noone is in range any more, since afterwards you wont be able to grab anything you have to move towards since they can just step away in the turn it takes the hand to get a second action to grab. 

I'd argue that it's less an outright trap and more just one you need to think about a bit. If you're up against a mob of opponents, for example, you can place it in the middle of the scrimmage so even if the current target escapes, you'll have the opportunity to grab another before they have a chance to get away. Or you might be able to position it on a move so that the target has to decide between risking the save or having to take one or more attacks of opportunity getting out of reach. There will definitely be situations where it's better to drop the current cast of it, but with a little planning you can keep it going beyond the first passed save.

I think this is the spell Simon uses in the movie, not bigby's hand

Is the damage considered Magical?

Quote from CazadorJD >>

can this be use to restrain a large or huge creature?

 I have read that grappling rules suggest a medium sized hand could only restrain up to one size above... though the RAW doesn't mention "grappling" so I'd be interested to know what people think on this too. I think realistically anything thats huge+ would have the strength to resist the trap in the first place?

I would say sure, it can be used to restrain anything of any size, because the spell doesn't mention any size restrictions. The only exception would be creatures who have a general immunity to being restrained from some feature or other. This isn't grappling, so the grappling rules aren't relevant here.

Would the damage from this spell (and similar ones where an object magically created by the spell deals damage) be considered magical for the purpose of overcome damage resistance or immunity.

Personally I would vote no. To all intents and purposes you have magically summoned a tangible stone that you use to bludgeon things. The damage itself is not inherently magical, it’s just the physics of hard object vs squishy object.
