General information

 * Be the last team standing to win.
 * Dead allies can be revived by clicking in their gravestone and waiting a few seconds.
 * If an enemy dies, but their team remains alive, you can deny the enemy's revival by using their gravestone. This takes 20 seconds.

 * Click on a hero's icon to see their custom stats and abilities for this event.

Rooms

 * Clear rooms to get XP and gold. Fully cleared rooms will spawn a treasure chest in the center with gold, items, and healing.
 * Shops periodically appear in rooms. They sell items and healing potions.
 * Rooms closer to the center are more difficult and contain better loot.
 * Roshan destroys a ring of rooms every five minutes, starting with the easier outer ring. Players in destroyed rooms take very high damage per second.
 * The contents of the map are randomly generated each time you play, so while the rooms physically remain the same, their location, difficulty and rewards will differ.

Caps and bonuses

 * Players can only earn a maximum amount of Battle Pass points per week. This cap can be increased by leveling the Battle Pass.

Emoticons

Strategy

 * Dynamite can be used to destroy the otherwise impassable stone walls, or it can be sold for 800g, or it can be used as a 1000-damage nuke to an enemy team (with the proper setup, to ensure that it damages them). Be careful though, as placed dynamite will damage everyone in the radius, including yourself and your team.
 * Always open chests before going shopping. Often, whole assembled items will drop from chests, which may change your purchasing choices. Alternatively, you can sell the items you receive from those chests for gold.
 * Observer Wards can be placed on the other side of gates and stone walls to scout ahead.
 * Some heroes are better at clearing creeps, some are better at clearing "boss" units, and some are better at fighting enemy heroes. Try to find a good balance between these so that your team is not too weak in one area.
 * Some of the map is on higher elevation than others. Always try and fight enemy ranged heroes while you have the high ground.
 * Enemy corpses will always drop their items and current gold. Invest this gold into items to help you gain a lot of power quickly.
 * Always stay on the move. The timer is ticking and Roshan is moving inwards. Be careful not to get caught in a room he controls!
