Lord of Hatred launched on April 28, 2026: and there’s a window to grab the right things. Diablo 4 has a clear rule: when a season ends, characters and items transfer to the Eternal Realm, but seasonal mechanics and the Season Journey itself go dark. Knowing what transfers and what doesn’t: and pairing that knowledge with the best Diablo 4 boosting resources to save time: is the difference between walking into the new expansion ready and starting from scratch.
What Actually Transfers When the Season Ends
Before going over specific items to chase, it helps to understand the system. When Season 12 closes, your seasonal character moves to the Eternal Realm with everything in their inventory and stash. Seasonal mechanics: Killstreaks, Bloodied Items, Fresh Meat currency: disappear. Loot, Resplendent Sparks, Codex of Power entries, and cosmetics all stay. Renown tied to Altars of Lilith and map exploration also persists into Season 13. The Codex of Power is account-wide, so every Aspect you unlock this season is available to every character you ever create: at minimum roll, but free and forever.
Priority Targets at a Glance
The table below breaks down the four main farming categories, what they give you, and where to get them before the expansion drops.
| Category | What You’re Getting | Primary Source | Transfers? |
|---|---|---|---|
| Mythic Uniques | Bis gear, build-defining effects | Uber Bosses, Belial, Crafting | Yes: to Eternal Realm |
| Resplendent Sparks | Mythic crafting currency | Season Journey, Uber Lilith, Tormented Bosses | Yes: as items |
| Codex of Power Aspects | Permanent account-wide unlocks | Dungeon clears, salvaging Legendaries | Yes: permanently |
| Seasonal Cosmetics | Transmogs, mounts, trophies | Battle Pass Reliquary, Season Journey | Yes: cosmetics tab |
Mythic Uniques: The Items Worth the Grind
Mythic Uniques are genuinely build-defining, not just a stat bump. The priority targets heading into Lord of Hatred are The Grandfather, Ring of Starless Skies, Tyrael’s Might, and Shako: multi-season staples that will stay relevant until new expansion items settle the meta. Belial, the Exalted Lair Boss, deserves a special mention: he lets you choose your loot pool, which turns the standard 2% Mythic drop chance into something you can actually aim at.
The Season Journey guarantees three Resplendent Sparks through its rank milestones. Once you have Sparks, crafting at the Jeweler with two Sparks plus Legendary Runes gives you the exact Mythic you want: no RNG. The Blacksmith route with two Sparks gives a random result, useful when Sparks are flowing faster than your priority list. Mythic farming overview covers current boss drop rates in detail.
The most efficient Mythic farming sources in Season 12 are:
- Duriel and Andariel remain the highest base drop rate bosses in the game for Mythic Uniques.
- Belial (Exalted Lair Boss) lets you select a loot pool, effectively letting you target a specific item class.
- Mythic Prankster Nightmare Dungeons still drop one Mythic per run after the Season 12 nerf, making them worth running when a Prankster sigil appears.
- Resplendent Spark crafting at the Jeweler converts two Sparks plus specific Legendary Runes into the exact Mythic you want: zero RNG required.
Codex of Power: The Silent Long-Term Investment
The Codex of Power is the most underrated pre-expansion task. Every Aspect you unlock now is available account-wide: at minimum roll, but free and infinite-use. Aspects from dungeon completions go in permanently; those extracted from salvaged Legendaries save their roll too. The window before Lord of Hatred is ideal for clearing remaining dungeons and salvaging any high-rolled gear sitting unused in your stash.
Aspects worth locking in before the expansion:
- Class-specific offensive Aspects from Nightmare Dungeons are the highest priority since they directly multiply skill damage.
- Generic mobility and utility Aspects (like Wind Striker) are worth unlocking because they apply to every class you will ever play.
- Any salvaged Legendary with an above-average Aspect roll should go straight to the Blacksmith: saving the roll beats saving the item.
- Aspects introduced in the Season 12 Season Journey become permanent Codex entries once unlocked, so complete those chapters now.
Seasonal Cosmetics: The One Thing You Can’t Buy Back
Gear and Aspects can be re-farmed in new seasons. Cosmetics earned through the Season Journey and the Battle Pass Reliquary cannot. Season 12 uses the Reliquary system from Season 8: Favor Tokens earned through normal gameplay let you claim premium cosmetics without spending real money. They cap at 99, so spend them before the season ends. The Butcher-themed armor set and Fresh Meaty Barding mount cosmetic are the headline targets, both tied to Season Journey completion and gone when Season 12 closes.
Cosmetics to claim before Season 12 ends:
- The Butcher-themed armor cosmetics tied to the Season 12 Season Journey are only obtainable during this season.
- Butcher’s Fresh Meaty Barding mount armor is a time-limited reward from the seasonal Slaughterhouse activity milestones.
- Premium Battle Pass Reliquary items can be obtained for free via Favor Tokens, which are earned through regular gameplay with no purchase required.
- Any unclaimed Season Journey chapter rewards should be finished now, as the seasonal quest chain closes permanently at expansion launch.
Practical Pre-Expansion Checklist
Six days before Lord of Hatred drops, the priority order matters. Resplendent Sparks should be spent first: they won’t carry forward as crafting currency once Season 12 closes. Cosmetics are the harder loss, so Season Journey chapters and Favor Tokens come second. Codex dungeon clears fill whatever time is left. Altars of Lilith and map exploration are worth logging at least once per account, since that progress carries into Season 13 and skips a chunk of early-expansion busywork.
Final pre-expansion to-do list:
- Spend all Resplendent Sparks on targeted Mythic Unique crafting at the Jeweler before the season ends: they don’t transfer as crafting currency.
- Finish the Season Journey through at least Rank 7 to collect all three guaranteed Resplendent Sparks from the milestone objectives.
- Spend Favor Tokens on the Battle Pass Reliquary before the 99-cap and claim any unclaimed Season Journey cosmetic rewards.
- Log in on your highest-progression Eternal character to register Altars of Lilith and map discovery, which carries forward into Season 13.
Season 12 is a focused bridge into the expansion rather than a major content drop: the farming loop is clean, the crafting paths are reliable, and the cosmetic system is accessible without touching the shop. Six days is enough to check every box on this list if you work in order. Walk into Skovos with the best gear your current character can carry.
