Returns the age or maximum age of blocks and age for entities (there in no maximum age for entities).
For blocks, 'Age' represents the different growth stages that a crop-like block can go through. A value of 0 indicates that the crop was freshly planted, whilst a value equal to 'maximum age' indicates that the crop is ripe and ready to be harvested.
For entities, 'Age' represents the time left for them to become adults and it's in minus increasing to be 0 which means they're adults, e.g. A baby cow needs 20 minutes to become an adult which equals to 24,000 ticks so their age will be -24000 once spawned.

 │ │ └──── {list::2::1::1}: 4

 │ └──── {list::2::2}: 5

Where using %size of {list::*}% will only return 3 (the first layer of indices only), while %recursive size of {list::*}% will return 6 (the entire list)
Please note that getting a list's recursive size can cause lag if the list is large, so only use this expression if you need to!

Return the currently opened inventory of a player.
If no inventory is open, it returns the own player's crafting inventory.

Parses text as a given type, or as a given pattern.
This expression can be used in two different ways: One which parses the entire text as a single instance of a type, e.g. as a number, and one that parses the text according to a pattern.
If the given text could not be parsed, this expression will return nothing and the parse error will be set if some information is available.
Some notes about parsing with a pattern:
- The pattern must be a Skript pattern, e.g. percent signs are used to define where to parse which types, e.g. put a %number% or %items% in the pattern if you expect a number or some items there.
- You have to save the expression's value in a list variable, e.g. set {parsed::*} to message parsed as "...".
- The list variable will contain the parsed values from all %types% in the pattern in order. If a type was plural, e.g. %items%, the variable's value at the respective index will be a list variable, e.g. the values will be stored in {parsed::1::*}, not {parsed::1}.

The error which caused the last parse operation to fail, which might not be set if a pattern was used and the pattern didn't match the provided text at all.

The blocks associated with a portal in the portal creation event.

The amount of time before an entity can use a portal. By default, it is 15 seconds after exiting a nether portal or end gateway.
Players in survival/adventure get a cooldown of 0.5 seconds, while those in creative get no cooldown.
Resetting will set the cooldown back to the default 15 seconds for non-player entities and 0.5 seconds for players.

Create a new potion effect to apply to an entity or item type. Do note that when applying potion effects
to tipped arrows/lingering potions, Minecraft reduces the timespan.

An expression to obtain the amplifier of a potion effect applied to an entity.

Represents the active potion effects of entities and itemstacks.
You can clear all potion effects of an entity/itemtype and add/remove a potion effect/type to/from an entity/itemtype.
Do note you will not be able to clear the base potion effects of a potion item. In that case, just set the item to a water bottle.
When adding a potion effect type (rather than a potion effect), it will default to 15 seconds with tier 1.

The prefix or suffix as defined in the server's chat plugin.

A projectile's critical state. The only currently accepted projectiles are arrows and tridents.

The protocol version that will be sent as the protocol version of the server in a server list ping event. For more information and list of protocol versions visit wiki.vg.
If this protocol version doesn't match with the protocol version of the client, the client will see the version string.
But please note that, this expression has no visual effect over the version string. For example if the server uses PaperSpigot 1.12.2, and you make the protocol version 107 (1.9),
the version string will not be "Paper 1.9", it will still be "Paper 1.12.2".
But then you can customize the version string as you wish.
Also if the protocol version of the player is higher than protocol version of the server, it will say
"Server out of date!", and if vice-versa "Client out of date!" when you hover on the ping bars.

This can be set in a server list ping event only
(increase and decrease effects cannot be used because that wouldn't make sense).

The quit reason as to why a player disconnected in a quit event.

Gets a random item out of a set, e.g. a random player out of all players online.

One or more random characters between two given characters. Use 'alphanumeric' if you want only alphanumeric characters.

If strings of more than one character are given, only the first character of each is used.

A random number or integer between two given numbers. Use 'number' if you want any number with decimal parts, or use use 'integer' if you only want whole numbers.
Please note that the order of the numbers doesn't matter, i.e. random number between 2 and 1 will work as well as random number between 1 and 2.

Returns a random UUID.

The raw Minecraft material name of the given item.
Note that this is not guaranteed to give same results on all servers.
