Mob Arena Overview

Mob Arena is a cooperative team game in which you choose one of 7 Classes to battle waves of mobs and bosses using powerful Spells and Abilities.

Equipment is provided for you in the form of Classes - you do not (and cannot) use your own gear.

Classes and Abilities

Classes are a core system to Mob Arena. Each class has a different play-style, and a different ability pool to choose from. Abilities are special powers you can use to defeat mobs. Each class has a pool of 20 different abilities split evenly into 5 categories:

  1. Basic Abilities
  2. Secondary Abilities
  3. Tertiary Abilities
  4. Quaternary Abilities
  5. Ultimate Abilities

For each game, you may choose one ability from each category to use as your loadout. Loadouts may be edited in the Mob Arena lobby by clicking on the class you wish to select.

Abilities may be upgraded, up to Level 7. Each upgrade roughly increases the ability's effectiveness by 10% of the previous level.

Upgrading an ability can be performed from the Ability Selection menu in the Mob Arena lobby, and costs Tokens and Ability EXP, neither of which exist as physical items.

Tokens are earned from each game of Mob Arena based on your personal performance. Post-game reward crates can also award some extra Tokens.

Ability EXP is earned only from post-game reward crates, and are tied to a specific ability (e.g. Fireball EXP). Your reward crate can only give EXP for the abilities you had in your loadout that game.

Powers are passive effects that are active for each game of Mob Arena. They are unlocked very rarely from rewards crates, and can be upgraded up to Level 3. Once unlocked, they are permanent; however, you can only select one Power to be active per game. You must get all Powers of a previous tier before you can start upgrading Powers (e.g. to get a Level 2 Power, you must first unlock all Level 1 Powers).

Ultimate Abilities drain less Rage when used.

Gameplay Mechanics

The basic goal of the game is to slay mobs and survive as long as possible. Each arena does have an end, but depending on your Difficulty selection and player skill, you may or may not get to it. Dying is not permanent, as there are several ways to get resurrected:

Ways to get Resurrected

Upon getting resurrected by a class ability, such as Genesis or Monody, you will gain a temporary, but unclearable Weakness effect. On your first resurrection, you receive Brush with Death, which reduces your damage and healing ability potency by 25%. This debuff becomes Death's Door, which reduces your damage and healing ability potency by 50%, if you die again while Brush with Death or Death's Door is active.

When all players die, you will get an option to continue. Accepting the continue will place you back on the wave you died on, refund all consumables (spells, bandages) used that wave, and grant a cash bonus of $4,000 split among all players, or $500 each, whichever is greater. All players will also receive permanent potion effects for the remainder of the game. However, that wave will not contribute to your score, and future score and rewards earned from that point onwards will be reduced by 25% each time, stacking with the number of continues used.

2 I (1) I (1) I (1) 0.56x

You can select one of several difficulties when playing a Mob Arena. Note that lower difficulty indirectly reduces rewards since there's overall less mobs to kill, and they have lower health.

  • Swarm Waves - Spawns a very large amount of enemies in a short amount of time, but they have reduced health.
  • Boss Waves - Spawns a single boss monster, who has special Abilities of their own. Boss fights can have dialogue and multiple phases. When defeated, bosses drop a lot of money, several minor Spells (Striking or Flaming Impact), and one major spell (Equilibrium, Resurrection, Shielding, Forfeiture, or Rage).
  • Upgrade Waves - Usually happen after a Boss Wave. All dead players are resurrected, and sometimes gear gets upgraded.


The stockpile can be accessed by right-clicking with the chest on your hotbar.

You can share items and money with your team through this interface. Dying with spells in your inventory will deposit all of them into the stockpile if there's space (or drop them on the ground otherwise). However, money and bandages will NOT be deposited automatically on death.

Mob Arena Shop

Enemies drop money upon being killed. Money collected does NOT persist between games, and can be spent in the in-game shop accessible by right-clicking the book on your hotbar. Note that the prices can change per arena; listed below are the default prices.

Ending a Mob Arena will award a Loot Crate if you've earned at least 50 value. Everyone's loot crate will have the same base value, which is an average of your team's performance. The following game actions affect rewards, in order of importance:

  1. Non-trivial damage dealt
  2. Non-trivial health healed through Abilities
  3. Wave Reached
  4. Mob Killcount

Non-trivial actions refer to actions that actually contribute to the fight. For instance, waiting for mobs to naturally regen, then hitting them is considered trivial damage, and will not contribute to score. Similarly, healing someone who is at full health, or purposefully stalling the round to take more damage is considered trivial healing, and will not contribute to score.

Each crate can also have a random multiplier depending on what type it is:

Crate Type Chance Reward Multiplier
Old default x1.0
Normal ~1/4 x1.25
Intricate ~1/20 x1.5
Occult ~1/50 x2.0

Rewards include Enchanting EXP, Tokens, Ability EXP, and Rare Items.

  • Ornament Kits - can be crafted with weapons or tools to add a cosmetic skin. These can be removed at any time by putting the ornamented item in a crafting grid, preserving both the item and the ornament kit
  • Powers - unlockable passive effects you can use in Mob Arena
