Note that the client rates champions on a scale of 1-3, with champions that feature both None and Low in a particular strength being marked equally. In contrast, this Wikia uses a 0-3 scale for Toughness, Control, Mobility and Utility. Any champions listed as 0 can be considered a 1, officially.Damage - A champion's ability to deal damage.Toughness - A champion's ability to survive being focused.Control - A champion's ability to disable or disrupt enemies.Mobility - A champion's ability to move quickly around the map, blink or dash.Utility - A champion's ability to grant beneficial effects to their allies or to provide vision.Champion attribute overlay.png

Throughout the family of templates, fixed names are used for the parameters. (The parameter names are kept short to reduce counts for the post expand include size and the template argument size in cases where these are applicable.) However, not necessarily all parameters have been given a value: some parameters may not be applicable, while for some other parameters the value may just have not been specified yet. The table shows all parameters, and for each the value, if specified.

Derived data

True as_base is 0.625, rounded to 3 decimal places as 0.625[1]

At level 18, the attack speed is 0.911875

Retrieval of data items

{{data Shadow Assassin|pst2|as_base}}, using parameter selection template Template:Pst2, gives the parameter as_base, etc.

For retrieval of more data items it is more efficient to prepare a template for that, to be used as follows:

{{data Shadow Assassin|template name|..|..|..|..}}

so that this data template needs to be called only once.[2] The default template is Template:Champion data, producing this page.

The four parameters are optional, they are passed on to the prepared template as parameters 2-5.

A parameter being undefined or empty typically means the same, see below. {{data ..|pst2|..}} gives the empty string and the text "{{{..}}}", respectively. Therefore an application checking the parameter has to check both. Checking whether a result is equal to e.g. the text "{{{popinc}}}" cannot be done directly with #ifeq in a template which itself has also a parameter with that name, because if that is defined, there would be a comparison with the value instead of the text itself. Instead, it can be checked whether the first character of the result is "{", e.g.: {{#ifeq:{{padleft:|1|{{data {{{continent}}}|pst2|popinc}}}}|{|..|..}}.


In this template system each template contains various properties of a single entity, as opposed to the other common system, where a template contains one property (e.g. population or area) of many entities. Although that other system can be convenient if updates of a property for all these entities become available together, in the case of large-scale use of data on one page that other system can be problematic due to its inefficiency. This is because of the following:

  • There are often more entities than properties, and page counts (or in the case of #switch, average page counts) are proportional to the number of data items in the data template (if they are stored in a linear way, not in a tree, and not stored as unnamed parameters).
  • In the case of large-scale use of data on one page there are usually one or more tables, where an entity forms a row and a property a column, because there are often more entities than properties, and because this way the sorting feature allows sorting entities based on a property. In this template system this allows producing a row with only one call of the data template, making the count not grow faster than proportional to the average number of data items stored per data template, times the number of entities in the table.

The include part of the data template of an entity does not contain a long list of its sub-entities or their properties, because that would make this method inefficient too.
