Every guild quest, along with several side quests and encounters, allows the party to gain a quest keyword upon completion. These keywords do not have rules themselves but can be referenced by other quests or encounters. Most importantly, they can modify the endgame’s difficulty. During the endgame, each encounter’s setup describes which keywords affect it and how. The party compares its keywords to those listed in encounter setup and resolves the relevant effects.
There are 2 types of keywords, Major and Minor.
