Sephiria Side Bag Guide: Store Spare Items Without Losing Your Plan

What the Side Bag is confirmed to do

TEAM HORAY's announcement introducing Side Bag describes it as a feature for storing spare items. The same announcement makes its most important limitation clear: items in the Side Bag are inactive. It is therefore not another row of active build space and not evidence that a stored Artifact, Tablet, or other item is still helping your combat plan.

The announcement also says Side Bag is unlocked through Destiny Inscription. That makes it a progression feature, not something every new save must already show. If you cannot find it, first check the current Destiny Inscription requirement in your own game instead of assuming that an old screenshot shows the same unlock state.

Use inactive storage to protect a decision, not avoid one

A spare item is worth storing when you can say why it is not active right now. Perhaps it does not fit the current board, asks for a damage type you have not committed to, or may become relevant after you test another branch. That is a clear reason to preserve an option without pretending it is part of the build already.

Do not use the Side Bag as a mental shortcut for an unsolved board. If you cannot explain which active effect you are keeping and which condition would make the stored item worth returning, pause and read the item descriptions again. A small active board with a clear job is more useful than a large collection whose effects you have stopped tracking.

A four-step spare-item decision

This short check keeps a storage move connected to a real run question. It also prevents the easy mistake of counting a stored item as part of a Combo or other active effect when the official feature description says storage is inactive.

Keep the note concrete. You are not trying to predict the perfect final build; you are preserving information so the next decision has a visible reason.

• 1. Name why you are moving the item: no room, wrong condition, untested effect, or a possible later branch.
• 2. Confirm that the item becomes inactive in the Side Bag, then stop counting it as an active part of the board.
• 3. Keep the active board focused on the effects, Combo tags, and placement result you can currently see working.
• 4. Return an item only when a real change gives it a job, then recheck the board rather than assuming the old layout still works.

Move one thing, then verify the active board

Side Bag is most useful when it reduces clutter around one experiment. For example, test an unfamiliar weapon upgrade or place one Tablet, then decide whether the spare item now has a clear purpose. Change only that one variable before judging the result. Moving several items at once can hide whether the improvement came from placement, an active Combo, a new weapon action, or simply a different room.

The official 1.0 patch notes contain fixes involving a Tablet obtained into Side Bag and starting items kept after a Side Bag move followed by a Costume or Talent change. Those notes are a reminder to verify the board after a complicated swap or preset change. They do not justify inventing a universal bug workaround; use the current game behavior first and the official support path if you can reproduce a problem.

Keep the unlock and the active build separate

The Destiny Inscription question is whether Side Bag is available on this save. The board question is whether an item is active and earning its space in this run. Keeping those two questions separate makes both easier: verify the unlock through the live progression text, then decide storage and placement by the item's current effect.

When an item comes back out of storage, treat it like a new pickup. Read its current description, check its cells and conditions, and test the immediate result before investing more space around it. That process keeps the Side Bag useful as a reserve rather than turning it into another source of build confusion.
