Lost Ark Growth Boost Shop: Every New September Item

Lost Ark Growth Boost Shop is the new name for the Single Mode tab in the Growth Support Shop, and Dimensions Unbound adds four progression items to make the section more useful for Ark Grid and honing support. The change is small compared with the Dimensionalist or Tier 4 overhaul, but it matters if you have been looking for the old tab and wondering whether the shop was removed.

Lost Ark Growth Boost Shop now contains an Epic Astrogem Selection Chest, an Astrogem Processing Reset Ticket, a bound T4 Metallurgy Selection Chest and a bound T4 Tailoring Selection Chest. Amazon describes the update as a way to round out the shop’s support for current endgame progression rather than leaving the old Single Mode label attached to a broader set of items.

Lost Ark Growth Boost Shop replaces the Single Mode tab

Lost Ark Growth Boost Shop is not a separate vendor that needs to be unlocked from scratch. The existing Single Mode tab inside the Growth Support Shop has been renamed to Growth Boost. If you know where you previously spent the relevant shop currency, start there instead of searching major cities for a brand-new NPC with the new name.

The renamed tab better reflects the fact that the shop is no longer only about one style of content. Its new items support Ark Grid setup and Tier 4 honing, which are progression systems used much more broadly than the old label suggested.

Lost Ark Growth Boost Shop: epic Astrogem and reset items are new

Lost Ark Growth Boost Shop adds an Epic Astrogem Selection Chest and an Astrogem Processing Reset Ticket. Those two additions give the shop a direct connection to Ark Grid progression, which is useful in an update that is simultaneously trying to accelerate returning characters toward current endgame systems.

Check the live shop for purchase limits and currency costs because Amazon did not publish those numbers in the release notes. The confirmed change is the presence of the items; the in-game interface is the correct place to see the current transaction details for your account.

New item	Purpose
Epic Astrogem Selection Chest	Ark Grid support
Astrogem Processing Reset Ticket	Astrogem reset
T4 Metallurgy Selection Chest (Bound)	Tier 4 honing
T4 Tailoring Selection Chest (Bound)	Tier 4 honing

T4 Metallurgy and Tailoring support honing

Lost Ark Growth Boost Shop also adds a T4 Metallurgy Selection Chest and a T4 Tailoring Selection Chest, both marked as Bound in the September notes. These items sit naturally beside the update’s wider progression overhaul because normal honing now begins in Tier 4 rather than asking characters to grind through the older Tier 3 upper path first.

Bound status matters when deciding which character should claim shop support. Do not buy a chest on the assumption that it can be freely moved or sold afterward. Use the shop on the character or roster plan that actually needs the Tier 4 progression help.

Why the shop update matters after Dimensions Unbound

Lost Ark Growth Boost Shop looks like a minor UI change until it is placed beside Jump-Up Boost, Rapid Growth and the new 1660 South Rimeria II Powerpass. All of those systems are trying to move characters through the same modern progression band, and the refreshed shop provides another place to fill gaps with current materials instead of old Tier 3 stock.

For returning players, the simple rule is to stop searching for the old Single Mode tab name and review Growth Boost before spending elsewhere. The shop is not a replacement for the major September events, but its new Astrogem and Tier 4 items make it more relevant to a character that is actively climbing through the updated endgame route.

The shop refresh is also a useful reminder to inspect existing currencies after a major progression patch. A currency that looked low priority under the old Single Mode label may buy something relevant now that Astrogem and Tier 4 support has been added.
