Aether Mechanics & Refresh Costs
Base Mechanics and Natural Regeneration
Aether restores at a fixed rate of 1 point every 6 minutes. The hard cap is 240, meaning a depleted account takes exactly 24 hours for full natural recovery.
- Pro tip: Log in at least twice daily to spend excess Aether before hitting the 240 limit.
- Use the Garden Cafe daily to choose between 80 instant stamina or a 60 stamina Ether Vial Powder.
The Stamina Refresh Cost Curve
When potions run dry, you can refresh up to 8 times daily. Costs scale sequentially:
- Refresh 1 & 2: 50 crystals each
- Refresh 3 & 4: 70 crystals each
- Refresh 5 & 6: 100 crystals each
- Refresh 7 & 8: 150 crystals each
- What works: Always spend free Aether and Garden Cafe rewards before committing to the 50-crystal refreshes.

Optimal Farming Routes & Event Timing
Simulations and Captain Level EXP
Simulations drain Aether but grant vital Captain Level EXP for Promotion Missions. Time your heaviest spending around specific event windows.
- Overdrive - Simulation: Runs from 05/27/2026 (post-maintenance) until 06/02/2026 18:00 UTC. Grants 2x Gr

owth Currency. Limit Overdrive mode to 6 daily sessions to max out double rewards.
Event Milestones and Returnee Rewards
Special events heavily incentivize stamina consumption.
Toward the First Light: Requires heavy Aether spending to reach critical progression milestones.
Garden Cafe Returnee Present: Rewards returning players specifically for spending Aether.
In practice: Stockpile Ether Vial Powder and Tear of God items (from Growth Guide) before these events. Spend everything on day one to secure early milestone rewards and leaderboard positioning.
Advanced Stamina Management
Potion Stacking and Inventory Limits
Garden Cafe recovery items have a strict hold limit of 4 in your inventory.
- Ether Vial Powder (Garden Cafe) and Tear of God (Growth Guide) must be consumed before hitting this cap.
- Never claim your daily Garden Cafe stamina item if you already hold 4 recovery items.
- Choose the 80 instant stamina option at the Garden Cafe if your potion inventory is full.
Handling Offline Overflow
Natural regeneration stops exactly at the 240 cap. Failing to manage this wastes passive generation.
- 240 Aether takes exactly 24 hours to regenerate.
- If you sleep for 8 hours, ensure your stamina is below 160 before logging off. This prevents capping while you're away.
ROI and Account Security
Time vs. Currency Investment
Is buying crystals for stamina worth it? The first two refreshes cost 50 crystals each. Since a 60-crystal pack costs under S$1.00, the investment for an extra 120 Aether (with first top-up double) is minimal compared to the hours saved grinding.
- Prioritize the 50 and 70 crystal refreshes for the best ROI.
- Avoid 150 crystal refreshes unless you're pushing a critical endgame leaderboard.
Safe Trading Practices
buffget uses secure data handling for your Stove, NAVER, or Google credentials.
- Never share passwords in public forums or unverified Discord servers.
- Rely exclusively on established platforms with verified escrow and buyer protection.
- Change your password periodically after completing large transaction batches.
