Homebrew: Feat

v1.1.0

A feat in 5eTools is a commonly used variant rule that happens every 4 levels granting a special feature and powers.

Building a feat

As with any Homebrew item, make sure you have reviewed the _Meta section. If your file doesn't have it, it won't work.

Basic skeleton

To start, copy the following code block and fill the empty "" values.

Feat code block

"feat": [
    {
        "name": "",
        "source": "",
        "entries": [
            ""
        ]
    }
]

• "name" — the name of the feat.
• "source" — make sure it is the same as the "json" key in the _meta.
• "entries" — consists of text strings ("") separated by commas.

More options

Make sure you are adding these blocks in the same level as the "name", "source", etc.

Ability score increase

You can define an ability score increase from the feat. Really useful for filtering purposes.

"ability": [
    {
        "cha": 1
    }
]

You can also choose from a list of abilities.

"ability": [
    {
        "choose": {
            "from": [
                "str",
                "cha"
            ],
            "amount": 1
        }
    }
]

• "amount" — the quantity the ability score will increase.
• "count" — in case you want to give the option to choose more than one option (when not present, it defaults to 1).

Weighted options are a possibility as well.

"ability": [
    {
        "choose": {
            "weighted": {
                "from": [
                    "str",
                    "dex",
                    "con"
                ],
                "weights": [
                    1,
                    2
                ]
            }
        }
    }
]

NOTE: adding an "ability" to a feat will a line to the text entry (or inside the list, if there's one) detailing the ability score increase. If you prefer this line to not appear, add the following line inside the code.

"ability": [
    {
        
        "hidden": true
    }
]

Prerequisite

Some features will have a requisite, something that the player needs to fulfill if they want to be able to pick the feat, such as being a member of a certain race or having a high ability score. This is a very flexible category, so it is divided in several blocks.

Level

The simplest way to restrict by level is by Player Character level.

"prerequisite": [
    {
        "level": 10
    }
]

It is also possible to restrict by class/subclass level

"prerequisite": [
    {
        "level": {
            "level": 5,
            "class":{
                "name": "Fighter",
                "source":"PHB",
                "visible": true
            }
        }
    }
]

• "visible" — Governs whether or not the class name is visible in the list display/prerequisite line. *Not* recommended for features which implicitly carry a class restriction, such as Eldritch Invocations.
• To restrict by subclass, simply change "class" for "subclass"

Race

"prerequisite": [
    {
        "race": [
            {
                "name": "Elf",
                "subrace": "drow",
                "displayEntry": "Tel-quessir"
            }
        ]
    }
]

• "name" — the name of the race
• "subrace" — optional, name of the subrace
• "displayEntry" — optional long-form name to be used in the rendered entity.

Ability

Write the first 3 letters of the ability, followed by the minimum score.

"prerequisite": [
    {
        "ability": [
            {
                "dex": 13
            }
        ]
    }
]

Spellcasting

The ability to cast at least one spell

"prerequisite": [
    {
        "spellcasting": true
    }
]

Pact

Warlock pacts, like "Chain", "Tome", "Blade" or "Talisman".

"prerequisite": [
    {
        "pact": "Chain"
    }
]

Patron

Warlock patrons.

"prerequisite": [
    {
        "patron": "The Archfey"
    }
]

Spell

The knowledge of a spell.

"prerequisite": [
    {
        "spell": [
            "eldritch blast"
        ]
    }
]

• If the spell's source is not PHB, add it to the name followed by a | e.g. "Absorb Elements|XGE".
• If the name of the spell contains #c at the end, it will render as "Eldritch Blast cantrip".

Feature

Sometimes a feature is an advanced version of a previous one.

"prerequisite": [
    {
        "feature": [
            "Alert"
        ]
    }
]

Item

Mostly used for Artificer infusions.

"prerequisite": [
    {
        "item": [
            "A suit of armor or a shield"
        ]
    }
]

Psionics

The ability to cast psionic powers.

"prerequisite": [
    {
        "psionics": true
    }
]

Proficiency

Proficiency with different categories of weapons or armor.

"prerequisite": [
    {
        "proficiency": [
            {
                "weapon": "martial"
            },
            {
                "armor": "heavy"
            }
        ]
    }
]

• For weapons, choose between "simple", "martial" or the name of the weapon.
• For armor, choose between "light", "medium", "heavy" or the name of the armor.

Other

A free text prerequisite. Will render as "Special" in the table, with the text in the entry.

"prerequisite": [
    {
        "other": "Two eyes"
    }
]

To have a specific test in the table, use this format:

"prerequisite": [
    {
        "otherSummary": {
            "entry": "The full description",
            "entrySummary": "Short desc."
        }
    }
]

• "entrySummary" — used in short/list displays.

Reference Tag

How to link to entries within the "entries":

{@feat <name_of_feat>|<json_source>|<optional_text>

Example:
