To cast many long-lasting spells and use certain abilities in Baldur’s Gate 3, players must utilize Concentration. Although this vital spell mechanic appears frequently in the game, it isn’t immediately clear what it means and how players can maintain it in the middle of active combat.

What Is Concentration in Baldur’s Gate 3?
In order for certain skills and Cantrips to remain active, the player must maintain Concentration. If Concentration is broken, these long-lasting spell effects are lost, and the spell must be recast. If the caster is not interrupted, however, the spell will remain active, and more resources—such as spell slots—won’t be required to maintain their effects.
To identify if a spell requires Concentration, hover over it to see the description. Concentration skills will be tagged as such at the bottom right.
Typically, Concentration spells include ally buffs, enemy debuffs, and battlefield effects such as Silence or Blindness.
How to Maintain Concentration
You’ll need to keep your wits about you to ensure that you don’t lose Concentration in the midst of battle. As mentioned above, you can only have one Concentration spell cast at a time. If you’d like to have two consecutive Concentration spells active, another member of your party can cast one of your choosing. Additionally, you can cast as many non-Concentration spells as you like while still maintaining a Concentration spell.
Each Concentration spell will only last for a certain amount of time. The time is noted in the description, and it’s important to keep in mind that many spells will fall off on their own if you’re not careful. Some spells last a specific number of turns, while others will remain active until your next Long Rest. We’ve included the duration for each spell in the table at the bottom of this page.
When taking damage, your character must succeed in a Constitution Saving Throw in order to maintain Concentration and keep the spell active. Keeping your caster out of range of physical damage or positioning them behind cover to shield them from ranged damage can be vital in a fight.
Selecting the War Caster Feat will grant Advantage on Saving Throws to maintain Concentration, making it a perfect choice for powerful spellcasters.
While it may go without saying, if your character dies, the effects of any Concentration spell will end.
