Aghanim's Labyrinth Guide:
Dota 2 Aghanim’s Labyrinth is one of the hardest mini-game ever made. Here is an in-depth Aghanim's Labyrinth guide for the starters to get the drift:

Only 12 heroes are playable in this game mode.
These heroes are Magnus, Mars, Omniknight, Snapfire, Tusk, Sniper, Viper, Ursa, Weever, Disruptor, Winter Wyvern, and Witch Doctor.
Encounters:
You can choose 3 types of Challenges in this game mode. Heart, Coin and Chest. Here are the details of each path
Heart: Choosing a challenge with a Heart Icon will give Additional Life when you complete the Encounter. Depending on which Depth your party is in will inversely affect the number of Lives it will give.
Coin: Choosing a challenge with a Coin Icon will give Additional Gold when you complete the Encounter. This Gold is separate from the Gold given to you from the mobs of the Encounter. The deeper the depth the bigger the Gold reward.
Chest: Choosing a challenge with a Chest Icon will drop additional Neutral Items, Tomes, and Consumables when you complete the Encounter. The deeper the depth the higher the tier of Trinkets that will drop.

Bonus Tips For Aghanim's Labyrinth:
Winter Wyvern can bypass Trap Rooms if he uses his Arctic Burn before you enter the stage. Goes without saying that it lasts for as long as your skill lasts.
You can actually build an Aghanim's Scepter and Divine Rapier if you just buy the materials needed for it.
You can also give your ally's additional gold by giving them Iron Branch for them to Sell.
