You are not guaranteed to get a useful Legendary for leveling but, if you do, it can save you a lot of time. Take this weapon and use the 3rd Kanai’s Cube recipe to upgrade it into a Legendary.
Go to the Blacksmith and craft a Rare level 70 weapon (the weapon type will depend on your Class). Once inside, go to the end of the second level and you will unlock Kanai’s Cube. It will be located in the Ruins of Sescheron in Act 3 (at the top-right Waypoint of the map). If you have a pet, equip it using the Wardrobe at the Mystic, as it will pick up Gold for you. Take a Follower’s starting weapon, as it will be better than yours. Use the rewards from your Cache to immediately level your Blacksmith and Mystic to the max level. Once you’ve completed it, log on with your character and open the Cache you got as a reward. Complete a Challenge Rift before doing anything with your new character – you can access it from the Mode Selection screen. First Steps After Creating your Character
Note that these steps are for playing in Adventure Mode, as you won’t have access to most of these resources at the start of the Story Mode.
Luckily, there are a few ways you can make leveling a fresh character easier, and several strategies to use once you’re ready to start leveling, to hit level 70 within a couple of hours. This is especially true when a new Season starts, as you are forced to start from scratch to participate in each Season. Many players will want to get to the endgame content as quickly as possible.
