The Infinite Forest is one of the big new features in Destiny 2: Curse of Osiris, the game’s first expansion. Taking place on Mercury, the Infinite Forest is a Vex-made simulation. It’s essentially a small grouping of map-like puzzle pieces that fit together to form a bridge from one area to the next.
You will spend quite a bit of time in the Infinite Forest during your run through the Curse of Osiris campaign. Once that’s done, though, you’ll have three adventures to take you back in. Brother Vance requires the normal adventures before he allows you to start crafting weapons. The heroic adventures are a little more interesting and rewarding. You’ll gain access to all three of those after you finish them all on normal.
How to start one
Starting a heroic adventure is easy. Go visit Brother Vance in the Lighthouse. In his inventory, he’ll have the three normal adventures for you to repeat or three purple (Legendary) adventures for you. Choose from any of the three heroic adventures and return to the Infinite Forest gate on the other side of the planet. Here, your mission icon will direct you to a small statue of a stag. Make sure your party has the adventure and begin the mission.
There are three heroic missions currently available in Curse of Osiris, all of which focus on a specific faction: The Up and Up (Fallen), The Runner (Cabal) and Bug in the System (Hive). The adventures are actually fairly tough and have modifiers like the Nightfall. Make sure you have a crew that is ready to focus before jumping in.
What you get
In terms of rewards, heroic adventures fall somewhere between Strikes and Public Events. You’ll receive some gear, Mercury tokens and the new crafting material, Paradox Amplifiers. Grabbing these crafting materials can be tedious, so using heroic adventures to break up the monotony of grinding strikes can be helpful.
