Tiered Achievements
Some achievements come in tiers - bronze, silver, gold, or other progressions - where each tier is earned by reaching a higher milestone. As you cross into the next tier, the previous ones collapse so the list stays clean.

How Tiers Work
A tiered achievement is really a chain of achievements around the same theme:
| Theme | Tier 1 | Tier 2 | Tier 3 | Tier 4 | Tier 5 |
|---|---|---|---|---|---|
| Habit streak | 7 days | 14 days | 31 days | 100 days | 365 days |
| Taskmaster | 100 tasks completed | 1,000 tasks completed | |||
| Arena Champion | (milestone 1) | (milestone 2) | |||
| Demon Slayer | First vanquishing |
Each tier is its own unlockable - you earn the first tier when you hit 7 days, the second when you hit 14, and so on. Each tier grants its own gold and XP.
Viewing Progress on the Current Tier
In the achievement list, tiered achievements show:
- The highest tier you've already unlocked - displayed as earned.
- The next tier - displayed as locked, with its condition visible.
- Tiers beyond the next - collapsed or dimmed, accessible by expanding the card.
This way, your focus is on the next meaningful step, not a long list of future tiers.
Why Lower Tiers Collapse When Superseded
Once you've earned tier 3 of a chain, tiers 1 and 2 are automatically "past" achievements. The list collapses them so they don't clutter your current progress view - but they're still on your record, still counted, still displayed on the detail page if you expand the card.
Why collapsing matters
Without the collapse, a seasoned player's achievement list would be dozens of entries of the same chain, each just a smaller version of the current one. Collapsing keeps the list readable - you see the current tier and the next, not the ancient history.
Tier Rewards
Each tier grants its own one-time payout - gold and XP. Higher tiers pay more than lower tiers, since they're proportionally harder to earn.
A 365-day streak achievement is worth substantially more than a 7-day streak - both in terms of what it represents and the XP/gold it delivers.
Tiered vs Non-Tiered
Not every achievement is tiered. Single-tier achievements (bind to a specific condition like "First arena victory" or "Defeat your first demon") are their own one-shot unlocks.
Tiered achievements exist when the theme has a natural progression - streaks, counts, milestones that scale up over time.
Broken Tiers Still Count
If you break a habit streak, the tier you'd already reached stays unlocked - it records that you once had that streak, which remains true.
Starting a new streak puts you back at zero toward the next tier, but the earned tiers don't revoke. A player who had a 100-day streak, broke it, and is now at day 5 of a new streak still shows the 7, 14, 31, and 100 tiers as earned.
