Vanilla Changes

Boss Progression
Boss progression isn't changed in Pre-Hardmode, but it has been seriously overhauled for Hardmode. The Lunatic Cultists spawn after the defeat of the 3rd Mechanical Boss, and post Mechboss content such as Plantera, Chlorophyte, and Lifefruit begin spawning in the Jungle at the beginning of Hardmode.

The Temple Key is craftable out of a Jungle Key and Lizhard Shards.
