Baldur's Gate 3: 11 Tips & Tricks The Game Doesn't Tell You
7. Movement Line Secrets
Before clicking away with reckless abandon during combat scenarios, drag your mouse over where you want to move to and take a look at your movement line.
If a portion of the line is yellow, this means that you will be travelling over difficult terrain. This is important to note as difficult terrain slows your movement by half and may even result in you being entangled in overgrown vines. If a portion of the movement line is red, you'll likely be taking damage from the movement.
You should also watch out for the opportunity attack notifier of enemies, which takes the form of a red arrow pointing towards you. To avoid this opportunity attack, try jumping past their reach and then continue on as though nothing had happened.
