Achievement Checker lets you inspect the completion status of any achievement's individual criteria, even for achievements that Blizzard's UI hasn't unlocked yet (e.g. tiered achievement series where the next stage only becomes visible once the previous one is fully completed).
This is especially useful for content like Delves, where you can complete individual encounters at higher tiers long before the achievement tracking them becomes visible — Achievement Checker lets you verify your actual progress at any time.
Features:
- Shift-click any achievement (from the Achievements panel, chat, or links) into the checker window to instantly see per-criteria completion status
- Also works with plain achievement IDs — just type in the number
- Works on achievements that are still hidden/locked behind a prerequisite achievement
- Shows the Achievement ID directly in tooltips wherever achievements are displayed, so you no longer need to look it up on third-party sites
- Lightweight — no external dependencies, no database, no memory footprint
Usage:
Slash Commands:
/achcheck— Toggle the Achievement Checker window
Type /achcheck to open the checker window
Click into the input field
Shift-click an achievement anywhere in the game (or just type its numeric ID)
Click "Check Progress" to see a full breakdown of every criterion and whether it's completed
