Mythic for Foundry

An unofficial system implementation for playing the fan-made Halo: Mythic tabletop roleplaying game on Foundry Virtual Tabletop.

This system (once complete) provides character sheet support for various Actor and Item types, mechanical support for dice and rules necessary to play games of Mythic 4.0 and later. Coming soon will be compendium content for the Bestiary, the Flood, and all in-game items.

You can find video guides on how to install and use Mythic for Foundry on my YouTube channel.

Installation

The latest version of the Mythic for Foundry system can be installed using the manifest. On the Foundry VTT home page ("Configuration and Setup"), navigate to the "Game Systems" tab. Select "Install System," and provide the following link as the Manifest URL:

• https://raw.githubusercontent.com/AugmenTab/mythic/main/system.json

Any current or prior version can also be installed manually. You must clone or extract the system files to your Data/systems/mythic folder. Archives of all editions can be found in the Releases.

Always remember to back up your world files before updating.

Features

The following is a list of features offered by Mythic for Foundry.

Actors

All available Actor types in this system. Unimplemented items are italicized.

• Named Character: The primary Actor type for player characters, NPCs, and special Nemesis enemies. Nearly every aspect of this character sheet can be customized to fine-tune exacting stat requirements.
• Bestiary Character: The Actor type representing all unnamed mooks in the game, pulled from the Bestiary. These are made to be generic boilerplate templates for enemies that can be rolled from and adjusted quickly so as to represent a variety of similar enemies.
• Flood: An Actor type specifically for the Flood Bestiary, playing to their unique strengths and offers multiple avenues of adjustment for stats and swarm sizes.
• Vehicle: The Actor type for vehicles, permitting them to own items and weapons that can be swapped out to represent different configurations without requiring different sheets.

Items

All available Item types in this system.

• Ability: All purchasable abilities, as well as abilities unique to particular races or soldier types, traits, and augmentations.
• Armor: All wearable protective armor suits available in the game.
• Education: All purchasable educations.
• Equipment: All other items that don't fall into any other category are represented by this item type.
• Weapon: Anything that requires a to-hit roll or deals damage can be made into a weapon, which can be rolled from the owner's sheet to make attacks and post informative messages about the item to chat. Weapons come in three main categories: Ranged, Melee, and Thrown.

Compendia

All of the compendia that come included with this system. Unimplemented compendia are italicized.. Development on some Compendia will rely on as-of-yet unimplemented features or bug fixes, and thus won't be introduced until those dependencies are resolved.

Known Bugs

• Talents tabs do not apply active class when first clicking in from elsewhere.
• Experience Apply buttons are discarding first attempt to alter values, then work correctly afterward.
• Experience Purchase Price field does not focus coming off the Name field. It has to be focused a second time before the focus sticks.
• Equipping a new armor while one is already equipped updates the character sheet n + 1 times, where n is the number of armors the user has in their inventory. This is not so much a bug as it is a quirk of how it updates each armor in turn to unequip them before finally equipping the new armor. This may cause unforeseen issues, but as of yet none have been observed. In the future, I would like to batch these changes, then update them all at once.
• Not all Wound and Luck calculations are accurate for all soldier types with the 5.0 update.
