FoundryVTT module for the PF2e system, which allows creating temporary Effects from chat messages, to easily mark tokens as affected by a spell/action/item that doesn't normally have embedded effects.
To install, browse for it in the module browser, or directly copy the manifest link for the latest release .
To use, select one or more tokens and then right-click on a message in the chat. An option, "Extempore Effect", should appear. Clicking that option will grant a new Effect to all controlled tokens.
The Effect will have its name, description, level, traits, etc. match the message's item ("item" here being a spell, an action, a feat, a weapon, etc.). The duration will usually fit if possible (required some hardcoding and doesn't cover all bases). Afflictions will always start at Stage 1 and will expire after Stage 1's duration has passed.
The image will fit the item too, but not if it's a "default image" (like the default feat icon or any of the simple 1/2/3-action icons). To avoid having several Effects with the same image (and avoid the boring default images), this module will either use the image of the original item's token/actor, or will randomly pick a simple colored image.
As a bonus feature, right-clicking actual Effect messages will display an "Apply Effect" option to just apply that same effect to the controlled token. This is just a quality-of-life feature.
When you create an effect from an affliction chat message - such as the one from Scalathrax Venom - the module will attempt to give the effect a list of stages equal to the affliction's stage count, set the initial stage to 1, set the duration to the first stage's duration, and set the expiration to the end of the turn. These, altogether, do not automate affliction tracking - but they should at least help keep track of things nicely until the core system support is added.
If you hold the Shift button, the effect's sheet will be opened up for you to see and edit, after being applied. You can configure to use Ctrl instead of Shift, or to disable this behavior, in the module settings.
This is useful if you want to quickly edit the effect - for example:
You can shift+click an existing effect icon in the panel that appears in the top right corner of the screen, when controlling a token. This will open the sheet of that effect/condition, allowing you to read it and edit it. Useful if you want to get a refresher about its rules, or to edit a small detail about it.
This is less useful now that the core pf2e system allows editing effects from the effects panel.
This new keybinding, "Quick create empty effect", will do something similar to the Extempore Effect except with fully empty contents (not based on any message), also immediately opening the sheet for you to edit. The name will be untitled and the image will be a random icon (the randomness depends on screen position, so if you don't pan or zoom around you can keep creating random effects with the same icon, which is sometimes handy).
By default, this will only notify the GM about secret (unidentified) effects, though there is a setting to make it notify for all effects. When it triggers, it will both create a notification and create a chat message detailing which effect expired, what its duration was, which actor it applied to, and so on. If you have the PF2E automation setting for "remove expired effects" turned on, then this message will also include a button to reapply the just-removed effect.
Note that this will not work for tiny 1-round time changes (which happens in combat), because of technical difficulties. However, this is probably not a problem for you - if you have an effect with a duration measured in rounds, you probably aren't going to forget about it.
The "Create unidentified effects by default" setting can be used to change this default behavior, in which case all new extempore effects will be unidentified unless you hold Alt/Ctrl.
A lot of pf2e items, feats, features, etc have no image, so instead of using that uninteresting default icon this module will pick a random abstract color image from the core foundry magic icons. You can change this behavior with the "Prefer random images over default images" setting.
The setting called 'Shorten "Stage 2" to e.g. "[2/6]" in effect badges' will do... that. It may be useful if you use particular CSS themes that have less space for text in them (in the top right effects area).
