Roll20 Updates D&D 2024 Sheet and Builder with Upcasting, Action Modifiers

Roll20’s latest update to the D&D 2024 character sheet and character builder added a new modifier that lets DMs attach actions to features, effects, and conditions, improving automation for linked abilities and NPC behaviors. The change was documented in Roll20’s change log entry for Feb. 12, 2026 and follows a string of sheet improvements that started in October 2024.

Help Roll20 confirmed a major quality-of-life win: "Added the ability to upcast 2024 spells from the compendium." The developer also flagged a known edge case: "There is one known edge case where spells with multiple distinct attacks sometimes will not prompt for upcasting, a fix is in progress and you can expect it in a couple of days." Help Roll20 additionally stated that "Upcasting for legacy spells is in progress and coming soon," signaling that 2014-content compatibility is still being finalized even as 2024 spell upcasting goes live.

Interface tweaks landed alongside the upcasting feature. Help Roll20 reported it had "Made some small updates to the layout of the Spells Tab of the PC sheet (e.g. reduced some spacing and updated the names of the different views)." The Feb. 12 changelog entry also referenced improved UI behavior and included the truncated phrase "spell section headers now stick to the to," which appears in the entry text as provided.

Roll20 expanded defenses and immunities handling for creatures and players with a new type: "Added Condition/Damage Defenses type for PC and NPCs; NPCs now have more defined condition immunity vs other defenses," according to Help Roll20. That change will affect how DMs model NPC vulnerabilities and immunities when migrating or building encounters.

The updates build on fixes and features shipped in October 2024. The Oct. 14, 2024 changelog added "modifier support for Advantage/Disadvantage on Saving Throws and Attacks, including situational effects" and fixed issues such as "a bug where ability scores were sometimes being cleared in the builder when leveling up your character." The Oct. 10, 2024 entry added attunement functionality, noting "Added functionality to attunement that allows you to add effects that apply either on attunement only or only when the item is also equipped."

Roll20’s roadmap lists many launched items that aim to make the 2024 ruleset usable on the platform, including "[Launched] Spell Upcasting of 2024 Spells," "[Launched] Compact Layout by Default," drag & drop support for proficiencies, feats, and features, and an NPC Compact Sheet. The company’s blog summarised the 2024 Player’s Handbook content counts as "12 classes, 48 subclasses, 16 backgrounds, 10 species, and 75 feats," underlining why sheet support has been a major engineering focus. Community-facing posts from Roll20 staff have said "Since January, we’ve been updating the Roll20 Character Sheet with better automation, smarter tools, and tons of bug fixes, all to make your D&D 2024 experience smoother and faster."

Players and DMs continue to push for workflow improvements. Forum user keithcurtis reported that "Unchecking items from your inventory does not adjust your weight (we are playing variant encumbrance so this matters)" and that users "Cannot customize the order of spells, features, inventory, etc. after creation." Alexis P. asked, "Any chance you can make a simplified version that is just the 2014 character sheet but able to use the 2024 content?" Roll20 replied through staffer Mic that an alternate "compact" layout exists and "You can switch between the layouts via the 'Manage Sheet' settings modal on the Player Sheet."

Next steps you can take this week: open a 2024 spell in your compendium and test upcasting, toggle the Compact layout via Manage Sheet, and if you hit the edge case with multiattack spells or find inventory/ordering issues, report the bug through Roll20’s Help page so the team can prioritize fixes. Share your test notes or a short screen clip in the Roll20 forum or subreddit to help devs reproduce issues and to give your table immediate benefits from these updates.
