Method

The prerequisite list of each quest comes from the game quest data exported by escapefromduckov.net and agrees with the Bilibili wiki quest graph. Depth and the full prerequisite set are computed over that graph (src/rules/escape-from-duckov/quests.mjs); EXP and money are summed from the reward lines. Level requirements are not part of the chain. Every quest with its tasks and rewards is in the quest list.
