Now, let's clarify exactly what progress gets carried over into Season 1. You'll transfer across all of Diablo 4 Gold the map you've revealed previously, including every Diablo 4 Altar of Lilith you've claimed, although only the five major towns of Kyovashad, Cerrigar, Ked Bardu, Gea Kaul, and Zarbinzet will appear so you'll need to revisit the other waypoints for more Diablo 4 fast travel options.
The Season Renown related to revealing the map and claiming Altars of Lilith will carry over, so if you've completely cleared the fog and found every statue then you should be able to immediately claim the first two tiers of Renown rewards in each region, getting you five additional Skill Points and five more Diablo 4 health potions. For further Renown rewards during Season 1, you'll need to unlock more waypoints, take over Strongholds, complete quests, and clear Dungeons.
Knowing how to craft a Diablo 4 Malignant Invoker is essential if you're grinding your way through Diablo 4 Season 1, as it will increase both the quantity and quality of Malignant Hearts you can gather as you clear out the new Malignant Tunnels – which are appearing instead of regular dungeons in certain locations.
If you're trying to complete the A Plague of Hatred quest then you may be facing some difficulties, as the game isn't great at explaining how the various parts of this new system works and how to cheap Diablo IV gold use Invokers in Season 1.
