TL;DR
- Complete campaign or at least first three acts for mount access before season start
- Collect all 160 Altars of Lilith for permanent account-wide stat bonuses and renown

Properly preparing for Diablo 4 Season 1 requires strategic campaign progression planning. The seasonal narrative directly continues from the main story conclusion, making campaign completion mandatory to access Season 1 content without encountering significant spoilers. Successfully finishing the storyline on any character permanently unlocks the campaign skip option for all future characters, including those created specifically for the seasonal experience.

For players pressed for time, completing the initial three campaign acts remains crucial as this milestone unlocks mount functionality. Your seasonal character will immediately gain access to their mount at level 1, provided you’ve achieved this progression in the Eternal realm. Mount access dramatically accelerates travel efficiency, reducing time spent traversing Sanctuary’s vast landscapes by approximately 40-60% depending on your route optimization.
Common Mistake: Many players underestimate the time investment required for campaign completion. Allocate 8-12 hours for full campaign completion or 3-5 hours for reaching the mount unlock threshold in Act 3.
Select Your Class
Strategic class selection forms the foundation of your seasonal success. Each Diablo 4 class features distinct mechanics, ability synergies, and specialized builds requiring careful consideration. Analyze each class’s early-game power spikes, resource management requirements, and endgame scaling potential before committing to your seasonal main.

Advanced players should examine class-specific paragon board interactions and legendary aspect availability. Certain classes like Sorcerer excel at rapid early progression while others like Barbarian demonstrate stronger late-game scaling with proper gear investment.
Pro Tip: Create a leveling roadmap detailing skill point allocation at key levels (15, 25, 35) to maintain consistent power progression. Understanding your chosen class’s defensive capabilities and mobility options proves equally important as mastering damage rotations.
Discover Altars of Lilith
The Altars of Lilith represent one of the most valuable permanent progression systems in Diablo 4. These hidden shrines provide account-wide bonuses including permanent attribute increases, Murmuring Obols currency, and Paragon Points for endgame advancement. With 160 altars scattered throughout Sanctuary, each discovery grants 10 Renown alongside their permanent stat benefits.
Comprehensive altar collection requires systematic exploration using dedicated online resources. Popular community tools like the interactive Diablo 4 map provide precise locations for all altars, transforming what could be a 20+ hour exploration endeavor into a manageable 6-8 hour targeted collection session.

Gain More Renown
The Renown system has emerged as a critical preparation focus following confirmation that seasonal progression requires new characters. Beyond altar discoveries, renown accumulates through dungeon completion, stronghold clears, and waypoint activation. Maximizing renown before Season 1 launch provides immediate skill points, paragon points, and gold bonuses to your seasonal character.
Each region offers five renown tiers with progressively valuable rewards. Completing all renown activities across Sanctuary’s five regions typically requires 12-18 hours but provides permanent account-wide benefits that significantly accelerate seasonal progression.
Reveal the Map
Full map exploration represents another crucial preparation element. Clearing the Fog of War across all regions before Season 1 ensures your seasonal character begins with complete geographical knowledge, saving approximately 4-6 hours of exploration time.
Before the season commences, ensure you log into any character possessing completed progression milestones. Account-wide propagation occurs automatically, transferring map discovery, altar benefits, and renown progress to all seasonal characters.
Collect Malignant Hearts
Malignant Hearts constitute the defining seasonal mechanic for Diablo 4’s inaugural season. These powerful items drop exclusively from Malignant Enemies—corrupted variants of standard foes featuring enhanced abilities and improved loot tables.
Season 1 introduces four distinct Malignant Heart types, each providing unique combat enhancements:
Vicious Heart – Offensive power specialization
Brutal Heart – Defensive and utility enhancements
Devious Heart – Crowd control and tactical advantages
Wrathful Heart – Ultimate ability modifications and synergies

Malignant Hearts feature color-coded rarity systems and exclusive seasonal availability. These powerful items socket directly into jewelry slots (amulets and rings), creating build-defining synergies and power spikes unavailable in the Eternal realm.
Acquisition Strategy: Target Malignant Tunnels for specific heart type farming through invocation mechanics. Cormond’s Wagon provides crafting alternatives for obtaining desired heart variants.
The seasonal mechanics enable immediate engagement from level 1, providing substantial power advantages during the critical leveling phase. Early acquisition of even common Malignant Hearts can reduce leveling time by 15-25% through enhanced combat efficiency.
Theorycraft Build and Farm Gear
Sophisticated build planning separates elite seasonal performers from casual players. Develop comprehensive skill tree progression, identify critical legendary aspects, and plan paragon board pathing before Season 1 launch. Research community-tested builds while adapting them to your preferred playstyle and available resources.
Strategic gear preparation involves collecting low-level equipment with valuable affixes like +Skills, Cooldown Reduction, or Resource Generation. These items provide substantial early-game advantages, particularly when combined with the new seasonal mechanics introduced in Season 1.
Plan Leveling Strategy
Effective leveling strategies incorporate optimized route planning, monster density exploitation, and event participation timing. Advanced players should research experience bonus stacking through elixirs, party play, and seasonal mechanic integration.
Resource accumulation proves equally important—stockpile leveling gear, gems, and crafting materials in your shared stash. This preparation enables immediate gear upgrades and resource utilization upon reaching key level thresholds.
Learn the Season Mechanics
Season 1 launches with integrated mechanics designed for rapid power accumulation. The Malignant Heart system functions similarly to legendary gems from previous Diablo titles but with enhanced customization and farming depth.
These seasonal power-ups insert directly into jewelry sockets, providing immediate combat enhancements. Early engagement with seasonal content from level 1 creates substantial progression advantages through optimized power curve management.
