Energy
Energy is a resource that fuels certain activities in ELHEXA. Only battle quests require energy to start — typically costing around 100 energy per run. Energy is also spent when tapping adventurer portraits for EXP and when speeding up quests at institutions.

Consumption
Energy is consumed by three activities:
- Battle Quests — Each battle quest costs a fixed amount of energy (typically 100). Normal production quests do not require energy.
- EXP Tapping — Tap an adventurer’s portrait on the home screen or card detail to convert energy into EXP. The energy spent per tap scales with your Energy Rank.
- Quest Speed-Up — Tap on an active quest at an institution to speed up its completion. Each tap consumes energy based on your Energy Rank.
Energy Rank
Your Energy Rank determines three key values:
| Property | Description |
|---|---|
| Max Energy | The maximum energy you can hold. Starts at 600, increasing by 200 per rank up to 3,400 at Rank 15. |
| Regen Rate | How fast energy regenerates over time. Higher rank means faster recovery. |
| Per-Tap Cost | The amount of energy consumed per EXP tap or quest speed-up tap. Scales with rank. |
Energy Rank can be upgraded in the Shop for 100 Elhexa Crystals per rank, up to a maximum of Rank 15. Each upgrade also instantly refills your energy to the new maximum.

Recharging Energy
Energy regenerates passively over time, even while you’re offline. The recharge rate is affected by your Energy Rank — higher rank means faster recovery. When you return, your energy will have recovered up to your current maximum.
Energy Refill
When you need energy now and don’t want to wait for regen, you can top up instantly from the Refill panel. Each refill adds a full tank — your entire Max Energy — on top of whatever you currently have.
Refills come in two tiers. Free refills reset daily — they are always spent first. Once the day’s free refills are gone, paid refills take over, costing Elhexa Crystals each — and paid refills are unlimited: there is no daily cap on how much energy you can buy.
| Tier | Cost | Daily Limit | Refill Amount |
|---|---|---|---|
| Free | — | 3 | Full |
| Paid | 50 Crystals | Unlimited | Full |
The panel lists both tiers — free on top, paid below. Free refills are always consumed first; the paid tier unlocks once the day’s free ones are spent. And because each refill stacks a full tank on top, your energy can rise above its maximum — natural regen simply pauses until you’re back under the cap.

Energy Rank Details
The table below shows how each Energy Rank affects your capacity, regeneration speed, and effective daily output. Daily energy assumes you start full, use all 3 free refills, and spend energy continuously throughout the day.
| Rank | Max Energy | Regen / hr | Full Charge | Daily Energy |
|---|---|---|---|---|
| 1 | 600 | 360 | 1h 40m | 11,040 |
| 2 | 800 | 378 | 2h 07m | 12,272 |
| 3 | 1,000 | 396 | 2h 32m | 13,504 |
| 4 | 1,200 | 414 | 2h 54m | 14,736 |
| 5 | 1,400 | 432 | 3h 15m | 15,968 |
| 6 | 1,600 | 450 | 3h 34m | 17,200 |
| 7 | 1,800 | 468 | 3h 51m | 18,432 |
| 8 | 2,000 | 486 | 4h 07m | 19,664 |
| 9 | 2,200 | 504 | 4h 22m | 20,896 |
| 10 | 2,400 | 522 | 4h 36m | 22,128 |
| 11 | 2,600 | 540 | 4h 49m | 23,360 |
| 12 | 2,800 | 558 | 5h 02m | 24,592 |
| 13 | 3,000 | 576 | 5h 13m | 25,824 |
| 14 | 3,200 | 594 | 5h 24m | 27,056 |
| 15 | 3,400 | 612 | 5h 34m | 28,288 |
Daily Energy = 4 × Max Energy (start + 3 refills) + 24h of natural regen. Rank 15 provides over 2.5× the daily energy of Rank 1 — and that’s just the free baseline: unlimited paid refills can push a big day as far as your crystals allow.
Energy Rank can be upgraded in the Shop for 100 Elhexa Crystals per rank, up to a maximum of Rank 15.
Tips
Battle quests are the only quest type that requires energy and give the best rewards. Spend your energy here first.
Normal production quests don’t consume energy at all. Keep your adventurers busy even when your energy bar is empty.

One of the most impactful progression milestones — it directly lets you do more each day. Rank 15 provides over 2.5× the daily energy of Rank 1.
