Automation Reference¶

This page details the structure of Avrae’s Automation system, the backbone behind custom spells and attacks.

Basic Structure¶

An automation run is made up of a list of effects. See below for what each effect does.

All Automation runs provide the following variables:

caster (AliasStatBlock) The character, combatant, or monster who is running the automation.
targets (list of AliasStatBlock, str, or None) A list of combatants targeted by this automation (i.e. the -t argument).

Target¶

{
    type: "target";
    target: "all"|"each"|int|"self";
    effects: Effect[];
}

A Target effect should only show up as a top-level effect. It designates what creatures to affect.

target

"all": Affects all targets (usually save spells)
"each": Affects each target (usually attack spells)
int: Affects the Nth target (1-indexed)
"self": Affects the caster

effects¶: A list of effects that each targeted creature will be subject to.

Variables

target (AliasStatBlock) The current target.
targetIteration (int) If running multiple iterations (i.e. -rr), the current iteration (1-indexed).

Attack¶

{
    type: "attack";
    hit: Effect[];
    miss: Effect[];
    attackBonus?: IntExpression;
}

An Attack effect makes an attack roll against a targeted creature. It must be inside a Target effect.

hit¶: A list of effects to execute on a hit.

miss¶: A list of effects to execute on a miss.

attackBonus¶: optional - An IntExpression that details what attack bonus to use (defaults to caster’s spell attack mod).

Variables

lastAttackDidHit (bool) Whether the attack hit.
lastAttackDidCrit (bool) If the attack hit, whether it crit.

Save¶

{
    type: "save";
    stat: "str"|"dex"|"con"|"int"|"wis"|"cha";
    fail: Effect[];
    success: Effect[];
    dc?: IntExpression;
}

A Save effect forces a targeted creature to make a saving throw. It must be inside a Target effect.

stat¶: The type of saving throw.

fail¶: A list of effects to execute on a failed save.

success¶: A list of effects to execute on a successful save.

dc¶: optional - An IntExpression that details what DC to use (defaults to caster’s spell DC).

Variables

lastSaveDidPass (bool) Whether the target passed the save.

Damage¶

{
    type: "damage";
    damage: AnnotatedString;
    overheal?: boolean;
    higher?: {int: string};
    cantripScale?: boolean;
}

Deals damage to a targeted creature. It must be inside a Target effect.

damage: How much damage to deal. Can use variables defined in a Meta tag.

overheal¶: New in version 1.4.1: optional - Whether this damage should allow a target to exceed its hit point maximum.

higher¶: optional - How much to add to the damage when a spell is cast at a certain level.

cantripScale¶: optional - Whether this roll should scale like a cantrip.

amount¶: How much temp HP the target should have. Can use variables defined in a Meta tag.

higher: optional - How much to add to the THP when a spell is cast at a certain level.

cantripScale: optional - Whether this roll should scale like a cantrip.

Variables

lastTempHp (int) The amount of temp HP granted.

IEffect¶

{
    type: "ieffect";
    name: string;
    duration: int | IntExpression;
    effects: AnnotatedString;
    end?: boolean;
    conc?: boolean;
    desc?: AnnotatedString;
}

Adds an InitTracker Effect to a targeted creature, if the automation target is in combat. It must be inside a Target effect.

name¶: The name of the effect to add.

duration¶: The duration of the effect, in rounds of combat. Can use variables defined in a Meta tag.

end¶: optional - Whether the effect timer should tick on the end of the turn, rather than start.

conc¶: optional - Whether the effect requires concentration.

desc¶: optional - The description of the effect (displays on combatant’s turn).

Roll¶

{
    type: "roll";
    dice: AnnotatedString;
    name: string;
    higher?: {int: string};
    cantripScale?: boolean;
    hidden?: boolean;
}

Variables

lastRoll (int) The total of the roll.

Text¶

{
    type: "text";
    text: AnnotatedString;
}

Outputs a short amount of text in the resulting embed.

text: An AnnotatedString detailing the text to display.

Set Variable¶

New in version 2.7.0.

{
    type: "variable";
    name: string;
    value: IntExpression;
    higher?: {int: IntExpression};
    onError?: IntExpression;
}

Saves the result of an IntExpression to a variable without displaying anything.

name: The name of the variable to save.

value¶: The value to set the variable to.

higher: optional - What to set the variable to instead when a spell is cast at a higher level.

onError¶: optional - If provided, what to set the variable to if the normal value would throw an error.

Condition¶

New in version 2.7.0.

{
    type: "condition";
    condition: IntExpression;
    onTrue: Effect[];
    onFalse: Effect[];
    errorBehaviour?: "true" | "false" | "both" | "neither" | "raise";
}

Run certain effects if a special condition is met, or other effects otherwise.

condition: The condition to check.

onTrue¶: The effects to run if condition is True or any non-zero value.

onFalse¶: The effects to run if condition is False or 0.

errorBehaviour¶

How to behave if the condition raises an error:

"true": Run the onTrue effects.
"false": Run the onFalse effects. (default)
"both": Run both the onTrue and onFalse effects, in that order.
"neither": Skip this effect.
"raise": Raise the error and halt execution.

AnnotatedString¶

An AnnotatedString is a string that can access saved variables. To access a variable, surround the name in brackets (e.g. {damage}). Available variables include:

implicit variables from Effects (see relevant effect for a list of variables it provides)
any defined in a Roll or Set Variable effect
all variables from the Cvar Table

This will replace the bracketed portion with the value of the meta variable.

To perform math inside an AnnotatedString, surround the formula with two curly braces (e.g. {{floor(dexterityMod+spell)}}).

IntExpression¶

An IntExpression is similar to an AnnotatedString in its ability to use variables and functions. However, it has the following differences:

Curly braces around the expression are not required
An IntExpression can only contain one expression
The result of an IntExpression must be an integer.

These are valid IntExpressions:

8 + proficiencyBonus + dexterityMod
12
floor(level / 2)

These are not valid IntExpressions:

1d8
DC {8 + proficiencyBonus + dexterityMod}
