As you prepare to play Shadow of the Erdtree in Elden Ring, you must maximize your current build, gather the best equipment, and make sure you have the right tools to deal with any new situation that may arise. You’ll be ready to face any new challenges the DLC has in store by tuning your stats, upgrading weapons and Spirit Ashes, stocking up on consumables, and optimizing your gear. As you progress through the new content, don't be afraid to experiment and adjust.
Character Level
•Recommended Level: Players often suggest being at least level 120 for an optimal experience. This level allows you to have enough vigor, damage output, and resilience for the challenges ahead. However, if you're aiming for a particularly challenging playthrough or if you're new to Souls-like games, you might want to consider being between levels 100 to 150.
Stat Distribution
•Vigor: Ensure you have a high amount of Vigor to increase your health pool. The DLC's enemies and bosses are reportedly tougher, so surviving longer in combat is crucial.
•Main Stats: Depending on your build:
•Strength/Dexterity: For melee builds, make sure your weapon scaling stats are high enough to maximize damage output.
•Intelligence/Faith: For casters, ensure you can cast the spells you wish to use effectively.
•Arcane: If you're focusing on Bleed or Occult builds, this should be prioritized.
•Endurance: Don't neglect this, as you'll need stamina for dodging and attacking, especially with bosses that might require more precise timing.
Gear and Upgrades
•Weapons: Upgrade your main weapon(s) to the maximum level possible. Given that the DLC introduces new weapons, having a partially upgraded base weapon can be useful for experimenting with new gear.
•Armor: Choose armor for balance between protection and weight. Consider the type of damage you'll frequently encounter in the DLC; for instance, if there's a lot of magic, armor with good elemental resistances might be beneficial.
•Talismans: Equip talismans that provide benefits like increased damage, health, or resistances. Consider switching talismans based on the situation or enemy type.
•Flasks: Ensure your Flask of Crimson Tears is fully upgraded for maximum healing potential. Also, customize your Flask of Wondrous Physick with Crystal Tears that might give you an edge in combat.
Preparation Steps 
•Defeat Required Bosses: You'll need to have defeated Mohg, Lord of Blood, to access the DLC. Ensure you're ready for this fight with the right level and gear.
•Explore and Collect: If you haven't already, explore the base game to gather all possible upgrade materials, spells, ashes of war, and talismans. These can significantly enhance your capabilities.
•Spirit Ashes: Upgrade your favorite Spirit Ashes. They can be lifesavers in tough boss fights, especially if you're playing solo.
•Respec: If you're interested in trying out new builds for the DLC, stock up on Larval Tears to respec at Rennala. This allows you to experiment with different playstyles without starting over.
Community Tips 
•Be Ready for Challenge: The DLC is designed to be challenging, similar to facing Malenia from the base game. Expect tough fights and plan your approach carefully.
•Explore: The Land of Shadow is vast, and exploration can yield significant advantages in terms of gear and knowledge of the environment.
•Engage with NPCs: New character questlines are introduced, and engaging with these can provide unique gear, insights, and story elements.
•Ensure you have a healthy stockpile of Rune Arcs to activate your Great Runes. Use them sparingly but strategically, especially when heading into tougher encounters.
Conclusion
By following these guidelines, your character should be well-prepared to tackle the "Shadow of the Erdtree" DLC. Remember, while level and stats are important, skill, strategy, and familiarity with game mechanics will also play a crucial role in your success.
