⚔️ Arena Guide

Welcome to the whirlpool waters at the deepest reach of the archipelago. Arena is LevelUp Land's competitive division, made up of multiple game worlds, each with its own theme and rules. The first world now open is NU World — a proving ground running entirely on BNB Smart Chain: 100 warriors enter, the draw is randomized on-chain, the victors are crowned, and the fallen become Spirits — yet hold the vote that decides the fate of the Epoch. This guide uses NU World as its example; when new worlds open, their own rules pages will apply.

NU World runs multiple battlefields at different ticket prices in parallel: a light battlefield at 1 USDT, alongside high-stakes battlefields at larger amounts. Rules, odds, and distribution ratios are identical across all battlefields, with prizes scaling proportionally with the ticket price. All amounts on this page use the 1 USDT battlefield as the example.

Quick Start: Enter in Five Steps

Link your wallet — bind your BSC wallet address in your profile, and make sure it holds enough USDT (plus a small amount of BNB for on-chain gas fees).
Pick a battlefield — go to /arena and choose a round that is "On Sale" (battlefields at different ticket prices run in parallel). Each card shows the ticket price, current progress (e.g. "87/100 entered"), and the round's position within the Epoch (e.g. "Battle 3 / 11").
Buy a Battle Soul — purchase this round's ticket at that battlefield's price. Each address may buy 1 per round. Once the purchase succeeds, you receive an on-chain NFT: your Battle Soul.
Wait for the draw — once all 100 tickets sell out, the system requests a random number from Chainlink VRF and completes the draw. You can check the status any time under "My Holdings".
Reveal your fate — after the draw, claim your Battle Soul's result: the NFT reveals your tier of fate and your Spirit's form, and any prize lands in your wallet instantly.

Reward Tiers: Your Fates at a Glance

After each draw, the 100 warriors are randomly assigned to five tiers of fate (prizes shown for the 1 USDT battlefield; return multiples apply across all battlefields):

Fate	Count	Odds	Prize	Return	Mind Diamonds / person
👑 Sovereign	1	1%	14.25 USDT	14.25×	0.75
🚩 Bannerlord	5	5%	5.70 USDT	5.7×	0.3
🏅 Glory	10	10%	2.85 USDT	2.85×	0.15
🛡️ Survivor	40	40%	0.475 USDT	0.475×	0.025
⚰️ Fallen	44	44%	0 (receives the Spirit's Choice)	—	0

Each round pays out 90.25% of the ticket pool as prizes (90.25 USDT on the 1 USDT battlefield), and 56% of participants walk away with USDT.
A further 5% of the pool feeds the Epoch grand prize pool; 4.75% is the platform reserve, against which an equal amount of Mind Diamonds is issued (4.75 per round on the 1 USDT battlefield — see the table above). A portion of the platform reserve also feeds the Growth Incentive Pool, rewarding users who keep growing in Level.
The Sovereign and the leaders also take their places on this round's Endorsement Board, earning the right to contend for the Epoch grand prize and the Grand Chieftain's throne.

💎 Mind Diamonds

Mind Diamonds are NU World's in-ecosystem resource and can be exchanged back into USDT at a 1 : 1 ratio. To exchange, go to Home → Me → Exchange rewards.

The Fallen: The Spirit's Choice

In NU World, falling is not the end. The Battle Souls of the 44 Fallen become Spirits, and each Spirit can make one irreversible choice — voting gives you a chance to win a USDT reward (see below):

🗳️ Endorse a Leader

Cast your one and only vote (weight 1.0) for any leader on this round's Endorsement Board. The vote is recorded on-chain and, once cast, is final — it cannot be changed or withdrawn. Your vote accumulates toward the Grand Chieftain's coronation at the Epoch's finale — and Spirits who take part in the endorsement stand a chance to share in the Epoch grand prize (see below).

The Epoch Grand Prize and the Grand Chieftain's Coronation

Every 11 rounds form an Epoch. 5% of each round's ticket pool feeds the grand prize pool (5 USDT per round on the 1 USDT battlefield), accumulating to 55 USDT by the Epoch's end, settled as follows:

Recipients	Share	Amount
Leaders on the Endorsement Board	≈90.9%	50 USDT
Endorsement voters (5 lucky Spirits drawn at random, 1 USDT each)	≈9.1%	5 USDT

At the Epoch's finale, the leader with the most endorsement votes is crowned Grand Chieftain, their name inscribed forever in the chronicles of NU World.

Claims, Refunds, and Common Operations

Claiming your prize

After the draw, go to "My Holdings" and hit Claim on each Battle Soul to reveal its result and collect the prize.
Prizes land in your wallet instantly — no lock-up, no delayed payouts. If an on-chain transfer temporarily fails, the amount is credited to your pending balance and can be claimed again at any time.
Claim rights belong to the NFT's current holder; each Battle Soul can only be claimed once.

Refunds

If a round fails to sell all 100 tickets within 24 hours, it automatically enters the cancellation process.
Buyers can reclaim the full ticket price, down to the last cent; the Battle Soul NFT becomes a commemorative "empty chest".

Fairness

Randomness comes from Chainlink VRF v2.5: the random seed's generation and cryptographic proof live entirely on-chain, verifiable by anyone — the platform cannot foresee or manipulate the draw's outcome.
Distribution ratios are hard-coded into the smart contract: prize tiers, grand prize pool contributions, and the platform reserve ratio are all locked in the contract — once a round opens, no one can change them.
One ticket per address: guaranteeing every round is a battlefield of 100 real participants.

FAQ

Q: What is the relationship between Arena and NU World?

Arena is the platform's competitive division (the parent), containing multiple independent game worlds; NU World is the first world to officially open. Future worlds will carry their own themes and economic parameters, each with a corresponding world guide.

Q: What do I need before I can join a battle?

A BSC wallet, enough USDT to cover your chosen battlefield's ticket price (light battlefields start at 1 USDT), a small amount of BNB for gas, and a LevelUp Land account with your wallet linked.

Q: I bought a ticket but the draw hasn't happened — what now?

The draw waits until all 100 tickets in the round are sold. If the round doesn't sell out within 24 hours, it is cancelled and you can claim a full refund.

Q: Can Battle Soul NFTs be transferred?

Yes. A Battle Soul is a standard on-chain NFT and can be transferred before its prize is claimed; claim rights move with the NFT to its current holder.

Q: I endorsed the wrong leader — can I change my vote?

No. Endorsement is an irreversible on-chain action — choose the leader you want to champion carefully before voting.

Q: Can Mind Diamonds be converted back into USDT?

Yes. Mind Diamonds can be exchanged back into USDT at a 1 : 1 ratio via Home → Me → Exchange rewards.

Q: Where do the platform's retained funds go?

Of the 4.75% platform reserve from each round's pool (4.75 USDT on the 1 USDT battlefield), a portion feeds the Growth Incentive Pool, rewarding users who keep growing along the Level Voyage Map — the heat of the Arena ultimately flows back to those who persist in growing.

A note on responsible play: Arena is on-chain competitive gameplay, and each round's outcome is decided by verifiable randomness. Play within your means, and enjoy the game and its story for their own sake.
