UFL Mini - Rules & Guide

Quick Start

1. Sign Up using only Username and Password. Your username will be your character's name. You can create multiple profiles for multiple characters.
2. Adjust your character attributes (only a few), select pronouns and gender (helps AI narration avoid awkward misgendering), and optionally upload avatar images and character reference images (up to 3).
3. Choose which moves your character can perform from a list of Default and Community moves.
4. Earn gold and items - fight PvE enemies to earn XP, gold, and loot. Buy or craft gear from the Shop or Market.
5. Create or join a room from the dashboard. You can fight other players (PvP) or challenge AI-controlled enemies (PvE).
6. Select your role: participant fights; observer watches, chats and comments.
7. As participant, click Join Room, then Ready. When all participants are ready, the match starts.

Core Rules

Stats

Each character has the following stats

• HP (Health Points) - Your total health.
• AC (Armor Class) - 0-20, default 10. Attacks must meet or exceed AC to hit.
• DMG (Damage Modifier) - Flat bonus added to some damage rolls (e.g., 1d6 + DMG).
• AP (Action Points) - Energy to perform moves each turn. Default 3 AP per turn.

Ranked vs Unranked Stats

You have both unranked stats and ranked stats.

Unranked stats are freely editable stat set for casual roleplay fights. There are no caps or restrictions - you can set them to whatever values you like. These stats are used in unranked (public casual) matches.

Ranked stats are a separate stat set used in competitive (ranked) fights. They start at baseline values and are upgraded using stat points earned through leveling up. This is your progression path - similar to an MMORPG, where you earn the right to improve your character.

Combat Flow

Most of this is handled internally by the game engine, but here are the core rules that it follows.

• Initiative - At match start each participant rolls a d20. Highest to lowest defines turn order; ties break by username.
• Attack Resolution - An attack hits on 1d20 ≥ target AC.
• Critical Hit - Natural 20; damage is doubled.
• Status
  • Alive: HP > 0.
  • Unconscious: HP ≤ 0.
  • Dead: HP ≤ −(Max HP ÷ 2). (e.g., if Max HP is 20, you die at −10 HP).
• Turns & AP - On your turn, use moves while you have AP > 0. When AP is spent, your turn ends - click End Turn to pass to the next fighter.
• Conditions - Some moves apply status effects (DoT, Stun, Stat debuffs/buffs). These expire after a set number of turns.

Match Types

• Unranked - Casual fights with no XP or ELO consequences.
• Ranked - Competitive fights. Win to earn XP, gold, and ELO rating. Loss still earns partial rewards.
• PvE - Fight AI-controlled enemies. Win to earn XP, gold, and item drops. Enemies have difficulty levels (easy, medium, hard, boss) affecting rewards.

Disqualification & Victory

• DQ Rule - Per-room setting: KO (lose on unconscious or dead) or Death (lose only on dead).
• Victory - Currently: last fighter remaining who is not disqualified.

Per-Room State

In-match stats (current HP/AP, move uses, status, conditions) are instanced per room, so you can fight in multiple rooms independently.

Moves

• Definition: Name, Damage (e.g., 1d6, 1d12, 1d20 + DMG), AP Cost, optional Uses per Match, Description.
• Global Library: All user-created moves are available for others to select.
• Selection: Each fighter builds a personal Move Set from the library.

Important: New fighters start with no moves selected. Go to Profile → Move Set and choose your moves, otherwise you cannot act in combat.

Creating Moves

Ability to creat your own moves tailored to your character's style is one of the key sandbox features of UFL. By creating different moves both through adjusting it's stats and using appropriate (or inappropriate! 😋) titles and description you can shift the entire dynamics and tone of a fight.

You can create purely physical wrestling moves like a Piledriver or Tombstone, you can create magical moves like a Fireball that burns your opponent over time (using DoT) or Ice Shard that freezes (Stun) your opponent. You can create sexual moves like a Kiss or a Tease that may lower your opponent's ability to hit a target, as if they are distracted, and more.

To add a new move to the global library, use the Moves page. Each move consists of:

• Name - A short, memorable name for the move.
• Damage - A dice expression (e.g., 1d6, 1d8 + DMG, 2d6+3). Use HEAL prefix for healing moves (e.g., HEAL2d4).
• AP Cost - Action points spent to use the move. Default is 1.
• Uses per Match - Optional limit on how many times the move can be used in a single fight. Leave blank for unlimited.
• Requirement - Finisher moves require a target state before use: below_25_pct (target below 25% HP) or unconscious. They can also have a Failure Penalty (e.g., backfire damage).
• Heal - Optional healing expression for support moves (e.g., 2d4).
• Cure Effects - Comma-separated list of effect types to remove from self (e.g., dot,stun).
• Description - Plain text description shown to players.
• Is Public - Whether other players can use your move in their movesets.

Move Effects

When creating a move, you can attach one or more Effects - special effects that are applied to the target (or yourself) when the move hits:

• Archetype - The type of effect:
  • dot - Damage over Time. Deals damage each turn at the start of the affected fighter's turn.
  • stun - Target loses their next turn.
  • stat_debuff - Reduces target's chosen stat (ac, dmg, hp, ap) for the duration.
  • stat_buff - Increases your own stat for the duration.
  • accuracy_debuff - Reduces target's chance to hit (lowers their d20 roll).
  • accuracy_buff - Increases your own chance to hit (raises your d20 total). Use to crack high-AC opponents.
  • loaded_dice - Warps the probability of the target's attack rolls. Positive magnitude loads rolls high (more hits & crits); negative loads them low. Works on self (load your own rolls high) or enemy (load theirs low).
• Magnitude - Effect strength (e.g., 2d6 for DoT damage, or 2 for stat penalties).
• Duration - Number of turns the effect lasts.
• Target - Who receives the effect: enemy or self.

Support and Benefits

UFL is a free-to-play game with no ads. We rely on community support to keep the game running. This section outlines the costs of running the project, how you can support us, and the benefits you'll receive in return.

Costs

Running UFL involves significant costs, including:

• Server Hosting: Hosting costs for our server. Undertow forum has ads, but it covers only 10% of the server cost.
• Development and Maintenance: Developing and maintaining this website takes significant amount of time.
• AI Services: Part of the AI inference is ran on our hardware, another part is run in the cloud. Both cost money - whether it's hardware and electricity or cloud AI credits.

Support Benefits

We try to make sure that the benefits are proportional to the support you provide, and we are only gating features that cost literal money on our end to run, like image generation - each image generation request costs us money. So you are paying directly for the image generation features.

Here are some of the benfits of supporting us on Patreon:

• Vouchers: Vouchers are AI credits. Right now you can use them to generate images (avatar variations and "!illustrate" command in chat). In time more features will be added that can be unlocked with vouchers.

Voucher Spending and Accumulation notes

Vouchers are handed out each month upon subscription renewal. They don't expire and will accumulate over time. When you make a donation 50% of your donation cost is converted directly to vouchers, with other 50% going to the server and development costs. I do believe this is fair.

Vouchers are consumed upon image generation attempt and are not currently refunded if the image generation fails. Given the nature of the website - be aware that if the image generation produces an NSFW image that is going to trigger a censorship filter, you will still be charged for the image generation attempt. This works this way because the cloud image providers (like nano banana, grok, etc) generate the image first, and then they check if it's NSFW. On our end we are trying to automatically prepare the ai-generation prompt to avoid NSFW images, but it's not always possible.

When generating avatar variations we rely on your character's first reference image as reference for avatar generation. If it contains extreme NSFW content the image generation may fail. You can work around that by cropping out the NSFW bits first, uploading this cropped image as your first reference image, and then generating avatar variations. You can later replace it with the full reference image again.

Some nudity, however, does seem to come through just fine, especially for non human characters. For example my own character reference image seems to work just fine, even though it technically includes nudity.

Trust & Safety

New accounts start with limited social capabilities to protect the community from spam and abuse. As you play, your trust level increases automatically.

Trust Levels

• New - Default for freshly created characters. Can fight in rooms and use basic features. Cannot vouch for others or file reports.
• Verified - Automatically earned after completing 5 fights. Can vouch for new players and file reports. Full access to social features.
• Trusted - Granted by admins to longstanding community members. Carries additional weight when vouching.

Vouching

If you are at least Verified, you can vouch for New characters from their profile page. Vouching signals that you've interacted with the player and they're legitimate. A character's vouch chain is visible to admins and helps identify alt accounts and bad actors.

Progression as Deterrent

Your character's level, items, ELO rating, and reputation represent real time investment. Banned characters lose all of this - creating a new account means starting from scratch. This is by design: the cost of being toxic should be tangible.
