The season pass is a type of leveling that rewards you with exclusive items and xp boosts, as well as exotic and luminous engrams. The pass has 100 total levels to progress through. While the free version only has rewards for every few levels, the paid version offers a reward at every level. Each level requires 100,000 experience points to level up and these can be earned by completing any activity in the game, with higher-tier activities rewarding more xp.
