This page of the Baldurs Gate 3 Game Guide provides information on how to perform long jumps and what's the use of jumping. This is a mechanics that you will be familiar with already from the prologue, but which has different applications throughout the game.
Each member of the team has the option to jump. It is one of the so-called Bonus Actions. Jumps can be activated both during real-time exploration of the game's world and during battles against opponents. In the latter case, they can be performed within a given round regardless of the "main" action.
When planning a jump, you need to fit within the white circle. The game can also refuse to execute a command if the chosen landing site is not stable, flat bedding.
The jump range depends on the value of the Strength skill. The higher the value, the further you can jump.
Important note – Don't plan to jump down from too high, even if the game allows it. That character may receive fall damage.
Jumps have two main uses in BG3:
- Reaching seemingly inaccessible places - while traversing the game world, take an interest in the higher or lower ledges and platforms you encounter. By jumping or jumping down, you can, for example, find a different path to your current destination or discover a whole new area where there may be some treasures or interactive objects.
- Getting close to or running away from opponents - jumping can be helpful in reaching enemies occupying higher or distant ledges, e.g. to reduce their high ground advantage or to prevent them from launching effective ranged attacks. However, you can also use them to escape, e.g. strong opponents aiming for hand-to-hand combat. By landing on a ledge with worse access, your character will feel safer.
