# OSRS Quest and Achievement Diary Progression — Guthixian Guidance

## Which OSRS quest should I do next?

A quest's value is larger than its direct reward screen. Guthixian Guidance models prerequisite chains, skill requirements, direct rewards and known secondary unlocks so quests can be ranked by what they enable for the account's current objective.

A quest is especially valuable when it unlocks several later quests, a new region, a combat system, useful equipment, an activity or an important account capability. The engine therefore favors dependency-aware progression rather than a fixed universal quest order.

## Which Achievement Diaries should I prioritize?

Achievement Diaries matter when their rewards improve repeated future work. The progression model gives diary completion meaningful weight because travel, utility, resource and skilling benefits can compound across later grinds. The best diary tier is therefore account-dependent: prioritize a reachable tier when its rewards improve activities the account is already doing or is about to do.
