GroupCheck 1E is a Roll20 GM utility built to speed up AD&D 1e style group resolution from one chat menu. After the GM selects linked tokens and runs !groupcheck , the script stores that selection and presents buttons for applying damage, morale, surprise, reaction, saving throws, ability checks, thief skills, non-thief hearing and stealth checks, detect invisible rolls, and token marker management, all resolved across the selected group instead of one token at a time. It pulls values directly from linked character attributes where needed, applies modifiers from prompts, reports clear pass/fail style results in a formatted GM whisper, supports custom token markers from the campaign, and includes a help/setup screen plus an optional morale modifier reference so the GM can run common combat and exploration checks quickly without digging through multiple macros or sheets.
