Aghanim's Labyrinth: The Continuum Conundrum

Aghanim's Labyrinth: The Continuum Conundrum is a gauntlet style event game mode available during the winter of 2021. It is the continuation to Aghanim's Labyrinth, where teams of four must battle their way through a series of monster-filled rooms of the Continuum Vault to reach the boss, The Primal Beast, at the request of Aghanim himself to save an alternate version of himself.

Gameplay

 * Teams of four enter a dungeon with several possible rooms. Finish the objectives of the room to move onto the next. Complete 17 rooms to beat the level.
 * Each player has a set number of lives. Upon dying, players automatically resurrect after 10 seconds. Dead teammates cannot be revived.
 * All dead players are automatically resurrected when a room is cleared.
 * The game ends when all players are out of lives and dead.

Heroes

 * 14 heroes with modified abilities are available for this game mode.
 * Additional 15 heroes from last year's Aghanim's Labyrinth are unlockable through Blessings and can be randomly unlocked on certain level rewards in the Battle Pass.


 * Heroes with an asterisk (*) are not playable initially and must be unlocked.

Abilities

 * Heroes have some modified or completely different abilities, either to better fit this game mode or for balance reasons

Scepter Shards

 * Scepter Shards are obtained by clearing rooms. They allows heroes to pick one of three random upgrades for their abilities.
 * At the start of the exploration of the Continuum Vault, you are given option between three Legendary Shards, which give unique traits to an ability, or in certain heroes, may give an entirely new ability.
 * Normal Rooms drop Common Shards, which give minor buffs to the hero or an ability's existing stats.
 * Elite Rooms and Trap Rooms drop Elite Shards, which give buffs that are twice as potent as Common Shards.
 * Boss Rooms drop another Legendary Shards.
 * This table shows all Legendary upgrades. Common upgrades are not shown. Crossed out upgrades were removed.

Types & Order

 * Rooms come in different types, and appear at different depths (order of exploration).
 * One of several possible rooms will appear at each depth (see list below). Teams can select which room to enter by channeling on an outpost, which displays the room's name, type, and rewards.
 * Most depths give players a choice between two types of rooms.
 * Challenge: Team must clear one of three challenges. These rooms can randomly receive a difficulty upgrade, making them an Elite room, which has 1 extra room effect (some of which are specific to elite rooms).
 * Combat: Clear all enemies.
 * Trap: Reach the end of an obstacle course.
 * Random: Either a Combat or Trap room. The type of room, as well as its room effects, will be revealed after the room has been selected.
 * Event: Occurs at random between various challenge rooms, they each contain an NPC that offers potential bonuses and upgrades, sometimes for a cost.
 * Boss: Fight against a powerful boss. The boss's statue can be seen at the start of each act, allowing the team to prepare.
 * Rest: Rest area before the start of Act 2 & Act 3 as well as before the final boss fight. Will have all three shops.
 * Bonus: Mini-game room that rewards team with evenly distributed gold.

Room Rewards

 * After a room is completed, players will be rewarded with a fixed amount of gold, experience point and 3 random Scepter Shards (pick one), except for Rest rooms and Aghanim's room. If a combat room has multiple waves, players will get experience point after each wave.
 * Challenge rooms also reward:
 * Gold: Varied amount of bonus gold, depending on depth.
 * Items: Neutral Items (items' tier depends on depth) or consumable items.
 * Life: Two Bonus Lives.
 * Elite Challenge rooms have double the rewards, including Elite Scepter Shards, which are twice as potent as regular Scepter Shards.
 * Trap rooms have treasure chests at predetermined locations with seemingly random rewards, which is twice as much if they are also an Elite Challenge rooms. Regardless of difficulty, they always give Elite Scepter Shards.

Challenge Room List

 * Combat rooms can also be Elite rooms.
 * Rooms with asterisk symbols are returning encounters from the original Labyrinth, and cannot be encountered in Apprentice difficulty.

Event Room List
Event rooms will appear at random throughout your way through the labyrinth, serving as a rest area before the next encounter. Unlike challenge encounters, you cannot choose what you will encounter. It does not replace any challenge rooms, so you will have to clear the same number of rooms regardless of whether one appears or not.

Each contains an NPC hero that offers various wares or upgrades. They sometimes cost gold, result in downgrades or may very well be completely free. They can appear between most rooms, but some rooms only seem to appear in certain acts (parts of the game).

Hidden items
Some items availiable in this mode are not displayed in the Shop. These items are:

Neutral items
