Separate playable content from currency, compare Blizzard's announced collection contents, and check what you already own before buying more.
Quick answer
Start by separating playable content from currency. Blizzard's Lord of Hatred announcement says Lord includes Vessel of Hatred, both expansions require the base game, and the Age of Hatred Collection combines the base game with both. Platinum is currency, not a base-game or expansion licence. Compare those contents with what you already own and want to play.
Game, expansion and currency are different purchases
Blizzard's Lord of Hatred pre-purchase announcement states that Lord includes Vessel of Hatred and that both expansions require the Diablo IV base game. It describes Age of Hatred Collection as the base game plus both expansions. Blizzard's BlizzCon 2026 recap gives the same grouping for its Nintendo Switch 2 collection.
Blizzard's post-launch overview describes Platinum as currency used for cosmetics and Battle Pass purchases. Buying currency is different from buying the base game or an expansion licence. This guide compares those product categories; it is researched buying guidance, not a hands-on review or a current checkout test.

Diablo IV ownership and product-category comparison
Your situation
Product category to compare
Avoid an unnecessary purchase
Own nothing; want the base game
Base-game licence
A Platinum pack is not the game.
Own nothing; want base game and both expansions
Collection explicitly including those components
Check the platform and actual included content, not just the edition name.
Own base game; want Lord
Lord expansion, advertised by Blizzard as including Vessel
Check that inclusion before buying Vessel separately too.
Own base game and Vessel
Compare the additional Lord content you want
Vessel overlap is not proof of a discount, refund or spare copy.
Own the content you want to play
No new licence needed for the same owned content
Treat optional cosmetics or Battle Pass purchases as a separate decision.
Switch 2 collection offer at Driffle
Driffle's Europe-labelled Nintendo Switch 2 digital-key listing explicitly names the Diablo IV base game, Vessel of Hatred and Lord of Hatred. It is a Nintendo offer, not a PC, Xbox or PlayStation licence. Check the eligible countries, seller and final checkout total before buying.
For an existing base-game owner, the advertised inclusion of Vessel with Lord matters: check that inclusion before purchasing Vessel separately as well. Already owning Vessel means overlapping content, not evidence of a discount, refund or second-copy entitlement.
If you own the base game and both named expansions, another package covering those same components is unnecessary for access to them. Additional extras need their own comparison. Choose the content you want and compare checkout totals rather than assuming a larger edition is automatically better value.
Check the platform and the exact package
Use Blizzard's announced contents as a reference, then check the game, included expansions and activation service on your chosen offer. A collection for Nintendo Switch 2 is not a PC purchase. Do not infer ownership on another platform merely from account linking or cross-progression.
Historical preorder extras and early-access wording are not current purchase guarantees. If your goal is an expansion campaign, compare playable-content entitlements rather than the size of a currency pack. If you already own the content you intend to play, there is no need to buy it again.
