Applying buffs
A buff can be applied through skills in a battle, curio interactions, town events, or through camping skills. Duration of buffs are decreased by 1 at the end of a Heroes turn. Buffs applied through camping skills last for the next 4 combats (counting the night ambush if there is one). Curio buffs last the longest, as they remain until the next camp. The Abbey and the Tavern can provide buffs (or debuffs) that will last for an entire expedition.

Making use of buffs in combat
By themselves, buffs are rather not useful, as a character usually has to wait until the next turn to make use of them, making them effectively skip a turn. That's why most buffs in the game ether apply to a whole party, deal small amount of damage to finish an enemy off, cure other status effects or have a health or stress heal to go with them. It's an important strategic choice when to apply buffs and when to push for damage.
