Summary

Season 15 of Diablo 4 has introduced some massive changes that weren't fully documented in the patch notes. From rune words in the Horadric Cube to Hell difficulty Prime Evils, there's a lot to unpack. If you're looking to skip some of the early grind, you can buy Diablo IV Items to give your character a head start. This guide will walk you through everything you need to know to maximize your seasonal experience.

Critical Warning: Don't Start Your Seasonal Quest Line Early

Before you dive into the new season, heed this warning: Do not start your seasonal quest line on a new character right away.

Here's why:

Bal will always drop Loric's Crown – the most important item this season.

If you kill him before level 70, you'll get a 400 Item Power crown instead of a 600 Item Power crown.

The same applies to the Stone of Jordan, which you'll receive 100% during the seasonal quest line.

You want both items at the highest Item Power possible. Wait until you're level 70 before progressing through the seasonal quest line.


Why Loric's Crown Is Essential

Loric's Crown counts as jewelry and increases the effect of any gem socketed into the helm.

Example benefits:

Bonus attack speed

Crit chance

2.1% bonus damage per enemy killed (stacks up to 200 times)

You can also socket damage reduction or damage soul splinters, but you'll lose crit chance – which doesn't matter much in the first eight Torment tiers.

Don't worry if you made the mistake – Hell difficulty Prime Evils will drop Loric's Crown again.


What Are Hell Difficulty Prime Evils?

From Torment 10 onwards, Prime Evil portals change from the normal yellow version to a red, dangerous version.

How to access them:

Play through their pinnacle dungeon once again.

Fight them another time.

No resources required – you can do this repeatedly.

Why farm them?

They are jam-packed with loot, including Greater Affix items and Mythics.

The loot explosion is massive.

Personal experience: Reached Torment 12 in 6 hours. The Blazing Scream build was doing 50 to 300 billion damage – enough to take out these Prime Evils. Had to be quite tanky because they hit hard. Ranged builds may have an easier time.


Choosing Your Prime Evil Power

During the seasonal quest line, you must choose a Prime Evil power. Here's how to swap away from it:

Splinters found in the world:

Splinter of Destruction

Splinter of Terror

Splinter of Hatred

How to get them: Kill the Prime Evils. You can go into their layers before Torment 10 (e.g., Torment 5, 6, 7) and kill them for another splinter. However, you need to get the exact splinter you're looking for.

Drop mechanics:

Bal does not drop Destruction – he could drop Terror.

Mephisto does not drop Hatred – he could drop Destruction.


Which Splinter Is Best?

Lord of Hatred (Recommended)

Boosts the first two nodes in the Pit, allowing you to upgrade glyphs as if your Pit was 10 levels higher.

Example: Finish Pit 120 → upgrade as if it were Pit 130.

More glyph upgrades = insane progression.

In Nightmare Dungeons, boss revive chance is increased, plus a bonus chest.

Reviving is very rewarding – had Kicksart respawn four times in a row.

Potential gold from a gold reserve Nightmare Dungeon escalation: 500 million to 1 billion gold.

Lord of Destruction (Second Best)

In the Undercity, gives 50% more experience orbs and increases monster power.

Increased monster power = more experience overall.

Lair bosses drop additional runes.

Nemesis portal appearance chance is increased.

Note: You need to push your seasonal rank to 18 to unlock these bonuses.

Seasonal Rank Progression

Your seasonal rank goes up in two ways:

Killing elites anywhere in the world.

Finishing Waking Nightmare dungeons – killing Diablo, Bal, Mephisto, or doing scripts like:

Unholy Altar

Chronicles Nightmare

Den of the Evil

Some are super fast – for example, Tarasha's Tomb (just go in, done). It can also appear as a Forgotten Wisdom – kill it for massive reputation.

You can also just finish elites over and over again.

As you rank up, you unlock the bonus power of your splinter. For example, the Hatred one says: "While in the Pit, enemies damaged by Ghost of Odium have a chance to drop progression orbs."

This is the main reason to take Hatred – more progression orbs in the Pit means shorter Pit runs and faster glyph XP.

Bonus effects:

Makes enemies vulnerable

Deals maximum life damage

Killing enemies gives more Ghost of Odium → more progression orbs


Horadric Cube and Secret Items

You can craft powerful secret items using rune words in the Horadric Cube. Here's a full list:

Stealth (Best Early Game Item)

Required runes: Tal + E

How to craft:

Get a white armor ( gamble for chest armors, hope for an ancestral one).

Take it to the Horadric Cube.

Remove affixes until it's a white item.

Add the Tal and E runes.

Transmute to a Greater Affix Stealth.

Stats:

Max life

Resource generation

Attack speed

Movement speed

Damage reduction

Bonus: You can reroll stats you don't like. Since you get so many Tal runes, you can make a low-level version for a new character.

Other Craftable Items

Enigma

Prudence

Lure

Rain

Call to Arms (gives 5 ranks to all skills if affected by shout skills – great for Barbarians)

Runes needed: Maltur, Tales, Amra, Malist, Om


Soul Splinters (General)

Soul Splinters are found everywhere throughout the world. Loot filters do not make them disappear.

Must-have splinters:

Splinter

Effect

Notes

Splinter of Lies

Bonus XP

Makes you always weakened and vulnerable. Wear unless fighting Hell Prime Evils.

Monster Power Splinter

Increases monster power

More experience. Insane value.

Bonus HP Splinter

Increases HP

Use when survivability is an issue.

Important: These splinters do not get more XP when put in Loric's Crown. For the crown, use:

Damage reduction

Bonus attack speed

Critical strike chance

Black Soul Stone

Amalgamation: Put five splinters in to upgrade them to a higher quality. Don't upgrade away if you don't have spare.

Rune offerings and invocations:

Bonus weapon damage

Deadly strike chance

15% damage reduction (put a soul in, put a su in front of it, cast five skills)

This might be more efficient than having Druid Earth and Bulwark as a constant barrier.


Charms and Seals

Don't make the mistake I did.

Value Reroll

Does not roll the affixes.

Only rolls the value.

Example: If you have impairment reduction, it will only roll the impairment reduction value.

Frankly useless unless you already have a seal with crit damage and want it maxed.

Horadic Reroll

Fully randomizes all base affixes on a talisman item.

Takes legendary upgrade materials you don't use.

Same as roll set charm, but you stay on the set charm.

Example: Have a Phoba with +4 Hellfire skills, but Beiru only at +3. Reroll Beiru and hope for something interesting.

Later, you'll have thousands of Pure Primordial Dust.

Cost: 100 resin (vs. 50 resin for reroll set charm).

Tip: If you have only one affix you don't want and all others you do want, it might still be better to hit transmute.

Unique Charms

Can get unique power rerolls.

Example: Mine is at 55% – horrible. Want it at 90%.

Any demon form grants all metamorphosis upgrades for free and they're 90% more potent.


Which Prime Evil to Farm?

Prime Evil

Difficulty

Notes

Diablo

Annoying

Has faces you have to go through with portals around him. Leave out.

Bal

Easy

Shortest dungeon. With enough movement speed, go quick. Wave-based event at the end.

Mephisto

Easy

Can be absolutely nuked.

Recommendation: Farm Bal and Mephisto. Skip Diablo.


Personal Progress

Paragon points: 167 after 8 hours

Torment level: Comfortable in Torment 12

Build: Blazing Scream (50 to 300 billion damage)

Glyph level: 70 at 6 hours in

Final Tips

Wait until level 70 before starting seasonal quest line.

Choose Lord of Hatred for Pit glyph upgrades.

Craft Stealth early – it's the best item.

Use Splinter of Lies for bonus XP, but swap to HP splinter for Hell Prime Evils.

Farm Bal and Mephisto for loot explosions.

Amalgamate soul splinters to upgrade them.

Be careful with rerolls – value reroll only changes the value, not the affix.
