Boss names will not be spoiled in navigation, but full names and mechanics are spoiled in actual boss guides. Other lore will not be spoiled.
My guides aim to accurately explain mechanics in intricate detail, and provide a rough guideline of strategies you can use to effectively deal with those mechanics. There are undoubtedly more “optimized” ways of dealing with or outright ignoring certain mechanics - if your group is executing those strategies, you should view my guides as more of a mechanics recap than a set of rules.
