# FAQ

## Q1. Is MetaMask account necessary to log in to SL:U?

A : Creating an account in SL:U doesn't require an existing cryptocurrency wallet. You can create an account using your social media accounts (Google, Facebook, Twitter), and a wallet will be automatically created for you.

## Q2. Can I import my SL:U wallet into MetaMask?

A : Yes, it is possible. You can import it using the private key.

## Q3. How is it possible that users don't have to pay any fees when using SL:U?

A : SL:U operates on the **Avalanche mainnet** and provides service without user fees.

This is possible because it runs on the Otherworld subnet called **Space**, which has a system that covers fees using internal **Fuel tokens**.

## Q4. Can I receive rewards immediately after opening a gate?

A : Opening a gate with a Gate Key rewards you with a **Random Box**. You can either wait for the gate to clear time or use Essence Stones to open it immediately for rewards.

## Q6. Can I obtain Shadow Army cards just by clearing gates?

A : Here's the process for acquiring a Shadow Army card:

1. Obtain **S-Rank Monster Cards** from **S-Rank random boxes** through gate clearing
2. Upgrade to **SB-Rank Shadow Army Cards** using S-Rank Monster Cards and **Essence Stones** (probability-based)
3. Progress from B-Rank to **SA-Rank**, and finally to **SS-Rank Shadow Army Cards** through upgrade

## Q7. Are upgrade attempts always successful?

A : No, upgrade succeeds based on probability rates. If an upgrade fails, **the card used for upgrading is preserved**, and **only the Essence Stones are consumed.**

## Q8. Can I join the SL:U Hunter Rankings competition right after registration?

A : If you are **D Hunter Rank and own a card**, you will automatically participate in the Hunter Rankings’ competition.

## Q9. How is Season Score determined?

A : Season Score is the sum of **Activity Score and Collection Score**.

Activity Score is earned through gate entries and leveling activities, while Collection Score is determined by the ranks of cards obtained from Random Boxes after clearing gates.
