This event is met only when player has specified item in his inventory. You specify items in a list separated by commas (without spaces between!) Each item consists of its name and amount, separated by a colon. Amount is optional, so if you specify just item's name the plugin will assume there should be only one item.
Example item emerald:5,gold:10
This event is met only when player is holding a specified item in his hand. Amount cannot be set here, though it may be checked with item condition.
Example hand sword
Alternative of specified conditions. This means that only one of conditions has to be met in order for alternative to be true. You just define one mandatory argument, condition names separated by commas. ! prefix works as always.
Example: or night,rain,!has_armor
Conjunction of specified conditions. This means that every condition has to be met in order for conjunction to be true. Used only in complex alternatives, because conditions generally work as conjunction. Instruction string is exactly the same as in alternative.
Example: and has_helmet,has_chestplate,has_leggings,has_boots
It returns true only when the player is closer to specified location than the specified distance. Just one mandatory attribute - location defined exactly as x;y;z;world;distance.
Example: location 100;200;300;survival_nether;5
Requires the player to have equal or more health than specified amount. The only argument is a number (double). Players can have 0 to 20 health by default (there are some plugins and commands which change the maximum) (0 means dead, don't use that since it will only be met when the player sees the red respawn screen).
Example: health 5.6
This condition is met when the player has a specified level (default minecraft experience). It is measured by full levels, not experience points. The instruction string must contain an integer argument.
Example: experience 30
The player must have a specified permission for this condition to be met. The instruction string must contain permission node as the required argument.

Example: tag quest_completed
The armor condition requires the player to wear specified armor, as an item defined in items.yml file.
Example: armor helmet_of_concrete
To meet this condition the player must have an active potion effect. There is only one argument and it takes values from this page: potion types.
Example: effect SPEED
There must be specific (Minecraft) time on the player's world for this condition to return true. You need to specify two hour numbers separated by dash. These number are normal 24-hour format hours. The first must be smaller than the second. If you want to achieve time period between 23 and 2 you need to negate the condition.
Example: time 2-23
There must be a specific weather for this condition to return true. There are three possible options: sun, rain and storm. Note that /toggledownfall does not change the weather, it just does what the name suggests: toggles downfall. The rain toggled off will still be considered as rain! Use /weather clear instead.
Example: weather sun
This condition requires the player to be below specific Y height. The required argument is a number or a location (for example 100;200;300;world). In case of location it will take the height from it and use it as regular height.
Example: height 16
This one requires the player to wear armor which gives him specified amount of protection (armor icons). The first and only argument should be an integer. One armor point is equal to half armor icon in-game (10 means half of the bar filled).
Example: rating 10
This condition is met randomly. There is one argument: two positive numbers like 5-12. They mean something like that: "It will be true 5 times out of 12".
Example: random 12-100
Sneak condition is only true when the player is sneaking. This would probably be useful for creating traps, I'm not sure. There are no arguments for this one.
Example: sneak
This condition will return true if the player has specified entry in his journal (internal name of the entry, like in journal.yml). The only argument is name of the entry.
Example: journal wood_started
This condition is met if the block at specified location matches the given material. First argument is a location, for example 100;200;300;world, and the second one is material of the block to check against, from this list.
Example: testforblock 100;200;300;world STONE
To meet this condition the player has to have specified amount of empty slots in his inventory.
Example: empty 5
To see details about parties read "Party" chapter in Reference section. This condition takes three optional arguments: every:, any: and count:. "Every" is a list of conditions that must be met by every player in the party. Any is a list of conditions that must be met by at least one player in a party (it doesn't have to be the same player, one can meet first condition, another one can meet the rest and it will work). Count is just a number, minimal amount of players in the party. You don't have to specify all those arguments, you can use only one if you want.
Example: party 10 has_tag1,!has_tag2 every:some_item any:some_location,some_other_item count:5
This condition will return true only if there is a specified amount (or more) of specified mobs in the specified area. There are two required arguments - monsters and location. Monsters are defined as a list separated by commas. Each mob type (taken from here) can have additional :amount suffix, for example ZOMBIE:5,SKELETON:2 means 5 or more zombies and 2 or more skeletons. The location is specified as 100;200;300;world;10, where last number is a range aroung the location in which the mobs will be looked for. You can also specify additional name: argument, with the name of the required mob. Replace all spaces with _ here.
Example: monsters ZOMBIE:2 100;200;300;world;10 name:Deamon
This condition allow for specifying multiple instruction strings in one, longer string. Each instruction must be started with ^ character and no other dividers should be used. The condition will be met if all inner conditions are met. It's not the same as and condition, because you can specify an instruction string, not a condition name.
Example: check ^tag beton ^item emerald:5 ^location 100;200;300;survival_nether;5 ^experience 20
This condition works in the same way as item condition, but it checks the specified chest instead of a player. The first argument is a location of the chest defined as 100;200;300;world (only integers!) and the second one is the list of items defined in the same way as in item condition. If there is no chest at specified location the condition won't be met.
Example: chestitem 100;200;300;world emerald:5,sword
With this condition you can check if the score in a specified objective on a scoreboard is greater or equal to specified amount. The first argument is the name of the objective, second one is amount (an integer).
