# Buildings & Items
### Buildings & Items
Buildings & Items are the key elements that determine how many Points your Land Block produces. Placing them on your Land Block is your main job as a player.
You can select buildings and items from the construction menu at the **bottom of your screen**.
Get new Buildings & Items by opening **Loot Boxes** in the **Store** or buying them from **NFT marketplaces**.

#### What Increases Earnings from Buildings & Items?
1. Rarity
Items and buildings come in 5 rarity levels:
* **Common → Uncommon → Rare → Super Rare (SR) → Special Super Rare (SSR)**
**Higher Rarity Benefits:**
* **Better Point Production**
* **Better Visuals**
{% hint style="info" %}
Higher rarity buildings may be larger in size.
{% endhint %}
2. Nearby Item Synergy
Compatible items and buildings placed near each other boost Point production. Try different arrangements to see which items work well together.
{% hint style="info" %}
Moving or removing items costs a small Point fee, so plan your placement carefully.
{% endhint %}
For a complete guide on which items work well together and which don't, check out the [Complete Item List](https://land-of-prosperity.gitbook.io/land-of-prosperity/in-depth-guide/buildings-and-items/complete-item-list).
3. Terrain Effect
Matching items to terrain gives bonus Points and mismatched items earn less Points.
| Terrain Type | Yield Bonus | Yield Penalty |
| ------------- | --------------------------------------------- | ----------------------------- |
| Tropical Land | ↑ 20% for tropical trees, water-related items | – |
| Ice Land | ↑ 25% for energy buildings | ↓ 10% for crops |
| Desert Land | ↑ 30% for desert plants, windmills | ↓ 15% for water-related items |

### Upgrading Buildings & Items
To upgrade buildings, players need **3 identical Building NFTs with the same rarity** to merge together. Players also pay **a small fee in Points**.
The NFTs used for merging get **burned** during the process, whether the upgrade works or not, meaning they will be eliminated from the circulation for scarcity.
There's always a chance the upgrade might fail - it's not guaranteed to succeed.
