There's a Legacy Collection that gives you Beyond Light, Shadowkeep, and Beyond Light. Beyond Light gives access to Stasis. The Lightfall expansion gives access to Strand. There's a Lightfall Bundle that gives access to LIghtfall wi6h the four seasons (that will expire) if you're crazy enough to grind them before The Final Shape drops in June. The Final Shape offers a bundle with the three episodes (replacing the seasonal model) if you're interested. This expansion introduces Prismatic - an ability that will combine different class abilities. This is a long term game LOL so you may consider buying during seasonal or Event Sales And you will eventually buy a lot of their products.
