• Cast items are defined the same as a Magic Item String.
• You can instead reference one of your predefined Magic Items.
• You can control what properties of Cast Items are ignored globally with general options.

Block data is a pair of Material and its possible block states. The material part is case insensitive, meaning it could be lowercase. Format:

material[state_1=value_1, state_2=value_2, ...]

block_without_state: "stone"
block_with_state: "quartz_stairs[waterlogged=true]"

• Costs represent a string list of spell reagents.
• Follows format: <type> <data>
• type can be: health, mana, hunger, experience, levels, variable, durability, or money (if Vault plugin is present).
• data for all types should be the quantity required (double value, 1 by default), except for variable, which should be the variable name before quantity. (e.g. variable varName 10)
• You can also require items as costs. Format for that is <item> <quantity>, where item should follow Magic Item String format, and quantity is 1 by default.

A boolean state may either be exclusively on, exclusively off, or toggling between either state. Use the following values for:

• on: on, yes, true, enable, or enabled
• off: off, no, false, disable, or disabled
• toggle: toggle, or switch

You can find a color picker tool here. May be in formats:

Hex number, from 000000 to ffffff (Red, Green, Blue). It may be optionally prefixed with #.

color_1: c0ffee
# Must be in quotes if it starts with # because it'll otherwise be a YAML comment.
color_2: #ff0000 

Each component may be in the range [0, 255].

color:
  red: 0
  green: 0
  blue: 0 

Very similar to Color, with an additional Alpha channel specifying color opacity. Add it to the existing Color format like so:

• String: Two hexadecimal digits before a color's "RGB" section (e.g. #c0ffee -> #ffc0ffee, where ff is 255 decimal, or 100% opacity).
• Config: Additional alpha value in range [0, 255] which equates to 0-100%.

Represents a decimal angle value used for pitch and yaw. It optionally supports starting with a ~ to specify a relative angle and its value may be an expression.

Defines a 3D vector (x, y, z). Config and List formats support dynamic values through expressions. Formats:

vector: "0,1,3" # "x,y,z"

vector:
  x: 10
  y: 4
  z: 6

vector_expanded:
  - 1
  - 4
  - 3
vector_compact: [1, 4, 3]
