   "instructions": "The **AD&D 1e Revised Sheet** includes all of the basic stats from the existing **AD&D 1st Edition Sheet** on Roll20 and should also be compatible with other OSR-style systems such as **OSRIC**. The **AD&D 1e Revised Sheet** may continue to change as needed/requested by the Roll20 community.\n**NOTE:** Updating an existing **AD&D 1st Edition Sheet** character with the **AD&D 1e Revised Sheet** should automatically migrate most attributes. That said, there are some sheet changes, newer attributes, and features that may require minimal, manual editing/updating in order to get full sheet functionality. I highly suggest testing the **AD&D 1e Revised Sheet** template on a copy of any existing **AD&D 1st Edition Sheet** game to see how the migration may effect your game. Simply change the character sheet template to the game settings to the **AD&D 1e Revised Sheet**.\n**Sheet Highlights:**\n - Sheet roll buttons for Ability-based skills, Saves, Thief Skills, Attacks, Spells, Special Abilities, and more.\n - Repeatable Weapons, Equipment, Spells, Special Abilities, Non Weapon Proficiencies.\n - Subcategories for Equipment.\n - Armor Details section that is linked to Equipment|Armor \n - Hover over fields and buttons to view the associated attributes name and descriptive text.\n - Roll templates for Attacks, &{template:attacks} and a General &{template:general} for custom macro {key}={value}\n - Monster sheet statblock\n**Sheet Auto-Calculations:**\n - Ability row attributes auto-fill according to the PHB.\n - Hit Points and AC.\n - Saves and Thief Skills\n - Total Armor bulk, Encumbrance, and Movement\n - Encumbrance and costs for Equipment, Armor, Weapons, and Coins.\n**Sheet Options:**\n - to-Hit Matrix or THAC0 table whispered to the DM when using the attack button.\n - Background Options (parchment, goldenrod, moldvay, etc.).\n - Hide/Show various sections of the sheet as desired. \n - Nearly all sheet macros are customizable. Attacks, Surprise, Initiative\n----------\nPlease post suggestions/questions/comments to the Roll20 Character Forum.\nhttps://app.roll20.net/forum/category/277980",
