# Skills

Skills mainly save you **waiting time** and strengthen your **empire**. They are leveled with **Gems <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/cur_gems.webp" alt="Gems">** and are kept across prestige ascensions.

There are **9 skills**, split into **3 modules**. Each module first has to be unlocked via a node in the [prestige tree](https://mebulalegends.bitmeup.com/wiki/en/guide/prestige/), after that you can upgrade the skills it contains with Gems as usual.

::: info Skills live in the prestige tree
The old Silver skills are gone, **Silver has been removed from the game entirely**. Skills are upgraded exclusively with **Gems**, and the modules hang off the last synergy nodes of the tree (Eternal Empire and Crown of the World).
:::

::: info No more combat module
The former combat module (Battle Claws, Guard Plating, Vitality, Weak-Spot Sense, Reflexes) has been removed. Its place has been taken by the **Time & Comfort** module. The prestige tree and gem skills no longer raise your Mebulis' combat power. That comes from levels, equipment, ultimates and [transcendence](https://mebulalegends.bitmeup.com/wiki/en/guide/transcendence/). If you had bought the old combat skills, you got gems back for them.

## Unlocking modules

Each module is opened by its own **unlock node** in the prestige tree (pure unlock, no effect of its own). These nodes sit on the **final tier** of the tree and cost **10 million PP + 3 prism seals** each:

| Module | Cost | Hangs off | Opens |
|--------|------|-----------|-------|
| <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/pr_wind.webp" alt="Time"> **Time & Comfort** (in the tree: Time Module) | 10 M PP · 3 seals | Crown of the World | 4 time & comfort skills |
| <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/nav_empire.webp" alt="Empire"> **Empire** | 10 M PP · 3 seals | Eternal Empire | 2 empire skills |
| <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/pr_compass.webp" alt="Comfort"> **Comfort** | 10 M PP · 3 seals | Eternal Empire or Crown of the World | 3 comfort skills |

::: warning The modules are true endgame
Together they cost **30 million prestige points**, roughly two thirds of the entire tree.

If you tap a still-locked module in the game, it tells you which prestige node you need for it.

Less waiting, more room: a faster idle chest, more room in Storage and a stronger [Resonance Chamber](https://mebulalegends.bitmeup.com/wiki/en/guide/resonance-chamber/).

| Skill | Icon | Max Level | Base Cost | Effect |
|-------|------|-----------|-----------|--------|
| Chest Tempo | <img class="ic-lg" src="https://mebulalegends.bitmeup.com/wiki/icons/ui_gift.webp" alt="Chest"> | 4 | 30 <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/cur_gems.webp" alt="Gems"> | −0.5 hrs idle chest interval per level |
| Inventory Expansion | <img class="ic-lg" src="https://mebulalegends.bitmeup.com/wiki/icons/nav_inventory.webp" alt="Inventory"> | 5 | 18 <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/cur_gems.webp" alt="Gems"> | +5 gear slots per level |
| Resonance Buffer | <img class="ic-lg" src="https://mebulalegends.bitmeup.com/wiki/icons/menu_graduation.webp" alt="Resonance"> | 5 | 24 <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/cur_gems.webp" alt="Gems"> | +2 hrs resonance storage per level |
| Resonance Yield | <img class="ic-lg" src="https://mebulalegends.bitmeup.com/wiki/icons/cur_xp.webp" alt="XP"> | 5 | 36 <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/cur_gems.webp" alt="Gems"> | +8% chamber XP per level |

- **Chest Tempo** stacks with the prestige node **Treasure Hunter**. Together they bring the idle chest from every 6 hours down to every 2 hours.
- **Inventory Expansion** counts everywhere: chests, dungeons and quests use your real limit, and [Storage](https://mebulalegends.bitmeup.com/wiki/en/guide/storage/) shows it.
- **Resonance Yield** applies to every chamber slot, even while Mebula Plus is running.

## <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/nav_empire.webp" alt="Empire"> Empire Module

Optimizes your gold production and automates expansion.

| Skill | Icon | Max Level | Base Cost | Effect |
|-------|------|-----------|-----------|--------|
| Construction Mastery | <img class="ic-lg" src="https://mebulalegends.bitmeup.com/wiki/icons/pr_construction.webp" alt="Construction"> | 10 | 15 <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/cur_gems.webp" alt="Gems"> | +8% gold for all buildings per level |
| Auto-Builder | <img class="ic-lg" src="https://mebulalegends.bitmeup.com/wiki/icons/pr_robot.webp" alt="Automation"> | 5 | 60 <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/cur_gems.webp" alt="Gems"> | Extends the build session by 50 min per level |

Everyone has the **Auto-Builder** in the empire from the start. It runs as a **build session** and expands automatically, even offline. Without the skill a session lasts 10 minutes, each level adds 50 minutes:

| Level | 0 | 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|---|
| Duration | 10 min | 1 hr | 1 hr 50 min | 2 hrs 40 min | 3 hrs 30 min | 4 hrs 20 min |

You get **1 start per day** (2 with Mebula Plus, VIP level 4 adds one more). With the prestige node **Comfort Omega** it builds along the Build Advisor's recommendation instead of blindly picking the highest building.

Faster quests, more loot and longer offline time.

| Skill | Icon | Max Level | Base Cost | Effect |
|-------|------|-----------|-----------|--------|
| Quest Speed | <img class="ic-lg" src="https://mebulalegends.bitmeup.com/wiki/icons/stat_speed.webp" alt="Quest speed"> | 5 | 24 <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/cur_gems.webp" alt="Gems"> | −8% quest duration per level (max −40%) |
| Treasure Sense | <img class="ic-lg" src="https://mebulalegends.bitmeup.com/wiki/icons/pr_key.webp" alt="Key"> | 5 | 24 <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/cur_gems.webp" alt="Gems"> | +20% Mebuli dust from [quests](https://mebulalegends.bitmeup.com/wiki/en/guide/quests/) per level |
| Diligent Sleepers | <img class="ic-lg" src="https://mebulalegends.bitmeup.com/wiki/icons/pr_moon.webp" alt="Offline"> | 5 | 18 <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/cur_gems.webp" alt="Gems"> | +1 hr offline time per level (base: 8 hrs → max 13 hrs, VIP levels add more hours) |

## Costs rise per level

The values above are the **base cost** for the first level. Each further level costs **×1.45** more.

```
Cost of next level = base cost × 1.45 ^ (current level)
```

**Example:** Resonance Yield (base 36 <img class="ic" src="https://mebulalegends.bitmeup.com/wiki/icons/cur_gems.webp" alt="Gems">) costs 36 Gems at level 0 → 1, but about `36 × 1.45⁴ ≈ 159` Gems at level 4 → 5.

## Recommended order

Since all three module nodes cost the same, you simply decide what comes first:

1. **Empire module**, Construction Mastery and especially **Auto-Builder** keep your GPS maxed out and so bring you your next prestige points faster.
2. **Time & Comfort**, if your Storage often runs full or lots of Mebulis are working in the Resonance Chamber.
3. **Comfort module**, **Diligent Sleepers** and **Quest Speed** if you often leave the game offline or run lots of quests.
