Core Gameplay

• Character Sheet (Edit Mode / Play Mode) for configuring attacks, power cost, and full ability values.

• Support for mental and social attacks (and defenses) as described in the Vastlands Guidebook (VLG).
• Descriptive results for saving throws, reactions, morale (NPC), and targeted attack rolls.
• Characters can spend hero dice to modify rolls or regain life (players must configure their main character in the User Configuration menu). Exploding dice are supported.
• Special roll results (magic numbers):
  • 1 = critical failure.
  • 13 = only one ammo or other resource left.
  • 20 = critical success.
• The system will automatically disable temporary active effects based on combat round/turn durations.

Items & Inventory

• Fully automated character inventory slots (each burden imposes a -1 penalty to all rolls, except hero dice rolls).
• Hovering over items in the inventory displays their key information (damage, range, power cost, etc.).
• Double-clicking an inventory item will open its sheet.
• Right-click any inventory item, trait, or burden to send a card to the chat.
• Easy item transfer between actors.
• Caravan cargo drop areas are highlighted when dragging an item.
• Items can be flagged as a hallmark (hallmark item leveling is not automated). The hallmark experience field supports math expressions.
• Items can be marked as notched or broken.
• Drag and drop a power into an Album of Power to add it to the Album; Referees can also extract powers from an album (copy power from the album to a new gear item).

Caravan System

  • Real container-based drag-and-drop inventory (sacks).
  • Shows total value and slots per sack for each container.
  • Overload indicator when the caravan capacity is exceeded.

• Customizable initiative rolls in NPC sheets.
• Shift+Click shortcut to skip opening custom roll dialogs.
• Ctrl+Click shortcut to make rolls in blind GM mode.
• Right-click roll results in the chat to open Apply as Damage and Apply as Healing menu options (applies to all selected tokens).

NPCs & Referee Tools

• NPCs support experience tracking (pets, sidekicks) and can use skills and traits in rolls.
• Referee utility functions are available directly as buttons in the token controls left menu (no need to use macros).
• Referee and Player utility functions are exposed in the system API for automation.

Customization & UI

• Highly configurable core game values (base defenses, item and trait slots, etc.).
• Chromatype customization:
  • Choose a main chromatype color for UI elements.
  • Dice So Nice integration with the "WTF Chromatype Dice" theme for Dice So Nice.
  • Separate configuration for Dice So Nice Chromatype color.

Localization
