Blizzard has revealed the upcoming itemization changes and new additions to crafting in the Season 4 Campfire Chat livestream. Here is a summary of everything you need to know about the upcoming itemization and crafting updates!

Season 4 PTR Overview, Itemization Rework — Campfire Chat Liveblog

Base Item Updates

• The amount of loot dropping will be reduced, but overall loot quality will be higher. The goal is for players to use crafting to customize their gear further.
• Smaller affix pool — many unused affixes have been removed from the game.
• More relevant and potent affixes, such as Core Skill Ranks and existing affix values will be adjusted so they can be felt.
• Legendary or Unique items will now be tradeable. Modifying an item, e.g. through Enchanting, will make it account-bound and thus no longer tradeable.
• Only Sacred items will drop in World Tier 3.
• Only Ancestral items will drop in World Tier 4.
• Legendary items will now have 3 affixes, down from 4.
• Rare items will now have 2 affixes, down from 4.

• Legendary items dropped from monsters level 95+ will always have 925 item power.
• Gems have been simplified and made stronger.
• Gold costs to reroll items at the Occultist now have a cap.
• Some crafting materials have been removed and consolidated.
• Forgotten Souls will now also drop from Whispers and rarely from Elites.
• Many Unique items can now drop in World Tier 1 and 2. All Unique items can now drop in World Tier 3.
• Uber Unique items start dropping from monsters level 55.

Codex of Power Updates

• All Legendary Aspects can now be found in the Codex of Power.
• Salvaging a Legendary item at the Blacksmith will upgrade the Aspect's values within the Codex of Power. These can be upgraded up to 16 times to reach their maximum potential.
• Legendary Aspects with maxed-out values will now only drop in World Tier 4.

New System: Greater Affixes
