In Destiny 2, seasonal bonuses are special perks that are available for a limited time during certain seasons. These bonuses can include things like increased experience gains, exclusive gear, or bonuses to certain activities. They are designed to offer players new challenges and rewards to keep the game fresh and engaging. These bonuses are usually tied to in-game events, and they can be earned through completing specific tasks or objectives.
Most, if not all of the items in this category are likely to be unavailable most of the year and will only become available during the season they were introduced in.
