This page and related pages summarize rule changes from the implementation of Dungeons and Dragons 5th Edition (D&D 5e) rules to Baldur's Gate 3 (BG3).
The rule changes described on this page and related pages are written with the assumption the reader understands the relevant D&D 5e rule. These pages will not explain what the D&D 5e rule is, only what the changed or altered BG3 rule is. These pages also include many BG3 features and abilities that are unchanged from D&D 5e to help a D&D 5e player quickly see which options have changed and which have not, and make decisions without having to do additional research. If the BG3 rule aligns with a OneD&D rule or other playtest material from D&D 5e, that is considered a rule change from D&D 5e.
There will be rapid changes to these pages at BG3's launch, so leaving relevant comments with any edits are strongly encouraged.

| Blur | - | - |

| Pass without Trace | Duration increased from 1 hr to until long rest for as long as the caster maintains concentration. | - |
