Following on from the version 1.0.0 update in this post , I have released another update to the Concentration mod - version 1.1.0. You can download it directly from GitHub: <a href="https://github.com/steverobertsuk/roll20-api-scripts/releases/download/concentration-v1.1.0/Concentration_v1.1.0.zip" rel="nofollow">https://github.com/steverobertsuk/roll20-api-scripts/releases/download/concentration-v1.1.0/Concentration_v1.1.0.zip</a> The update should reach the One-Click Installer soon. [1.1.0] - 2026-11-02
Brings Concentration up to the standard of the other Mods maintained by MidNiteShadow7. Version 1.0 settings, macros and commands keep working.
Fixed
Ending concentration posted nothing, so the last line in chat was often the earlier "is now concentrating on …" message, which read as if ending had started it again. Every way concentration ends now says so, and on which spell. Players clicking a reminder's Roll or Advantage button started or ended concentration on whatever token they had selected instead of rolling. The buttons now roll for the GM and the token's players. Damage was compared as text, so a bar going from 10 to 9 was not seen as damage. Bar values are compared as numbers. The One-Click settings on the Mod's page were never read. They now apply on startup when changed. Changing the HP Bar needed a restart. A failed save on one goblin took the marker off every token made from the same sheet. Unlinked tokens now concentrate on their own. Send Reminder To character whispered to the first word of the token's name. Whispers now go to the character by its full name, with a copy to the GM. 5e OGL spell cards that list charname before name gave the caster's name as the spell.
Added
End messages: "is no longer concentrating on …", "loses concentration on …" after a failed save, and "drops to 0 hit points and loses concentration on …". Spell switching: naming a different spell, or casting another concentration spell from a sheet, switches to it and says so. Putting the marker on or taking it off by hand starts or ends concentration, with a message. End at 0 HP setting (on by default): concentration ends without a save at 0 hit points. Save DCs stop at 30, as in the 2024 rules. end and status commands, with End buttons on the status card; help and journal . Concentration - Help and Concentration - Command Deck handouts (GM only). Custom token markers can be the Status Marker; changing it moves the marker on concentrating tokens. Commands from other Mods (playerid API ) are accepted, and a globalThis.Concentration API ( isConcentrating , spellOf , start , end , list ). Translations into 24 languages, with a Language setting. D&D 2024 spell cards use the message's character ID when Roll20 provides it. Deleting a concentrating token ends its concentration; new linked tokens of a concentrating character get the marker; pasted marked tokens are tracked.
Security
Spell cards only start concentration for characters the sender controls (or from the GM and other Mods); version 1.0 let anyone mark any character by posting a card with its name.
Changed
A D&D 2024 card that only mentions concentration in its text can start concentration but no longer counts as casting a concentration spell over an existing one. Repeated cards for the current spell are ignored. New chat cards in the same style as the other Mods, with the settings as buttons in one card. reset asks for confirmation and keeps who is concentrating. Source split into ES modules under src/ , bundled with Rollup; Node tests run the bundle against a Roll20 stub. docs/ folded into README.md , TESTING.md and DEVELOPERS.md .
