=== How to add a missing ability to a list ===

If an ability should appear in a table but doesn't, it means none of its data properties match the list's property keys. The recommended fix is to find a matching property in [[Data:AbilityData.json]] and add it to the list. Only use a raw ability name as a fallback if no suitable property exists.

Before editing, read the comment above the list you want to change, it describes what kind of abilities belong there.

'''Finding the right property''': Open [[Data:AbilityData.json]] and search for the ability. Look through its properties for one that represents the relevant mechanic, for example, a silence ability might have <code>SilenceDuration</code>. A good property is one shared by many abilities with the same mechanic, not something unique to one ability.

If a property is shared by many abilities but only some of them have the value you care about, use the <code>Key:Value</code> form to narrow it down. Ability scaling is the usual case: nearly every ability has a <code>Scale</code>, so <code>Scale.Type:cooldown</code> is what separates the ones that scale with [[Ability Cooldown]] from the rest.

After adding the property or ability name, test the table to make sure no unwanted extra abilities appeared. If they did, the property is too broad, consider using a raw ability name instead, or adding the extras to <code>exclude_abilities</code>.

If your new ability has special column values, you may also want to update [[Module:AbilityTable/ComplexRenderers]]. And if it needs a descriptive note, add it in [[Module:AbilityTable/Notes]].

==== Example: adding Affliction to the "healreduce" list ====

Say {{AbilityIcon|Affliction}} is missing from the heal reduction table. First, check the comment above <code>["healreduce"]</code> in the module, it says "Abilities that reduce healing on their targets", so Affliction belongs there.

Open [[Data:AbilityData.json]] and search for <code>affliction</code>. Looking through its properties, you find <code>"DisableHealing": 1</code>, that looks like exactly what we need.

Check if <code>DisableHealing</code> is already in the <code>["healreduce"]</code> list. It isn't, so add it:

<pre>
["healreduce"] = {
    "DisableHealing", "HealAmpReceivePenaltyPercent", "HealAmpRegenPenaltyPercent",
},
</pre>

Save and test the table with <code><nowiki>{{AbilityTable|healreduce}}</nowiki></code>. Affliction now appears, and no unexpected abilities were added, so the property was a good fit.
