Sephiria Side Bag Guide

Why Side Bag changed 1.0

Before Sephiria 1.0 (2026-07-31), every awkward artifact fought for active inventory grid cells. The Side Bag stores spare items inactive so you can keep exploration pieces during rooms and swap defensive or burst kits before bosses — especially the Chapter 6 Final Boss and Hard Mode elemental checks. Players who ignore Side Bag still play Early Access muscle memory; players who unlock it early treat the bag as a tactical toolbox.

Sephiria inventory and build gameplay — Side Bag mindset

How to unlock Side Bag

Side Bag is gated behind Destiny Inscription. After you earn enough Sapphires:

1. Open the inscription board in Bunnyville.
2. Find the inventory / storage branch (wording may vary slightly by language pack).
3. Purchase the Side Bag node.
4. Confirm the bag UI appears in the next run’s inventory screen.

Track the purchase on the Destiny Checklist so you do not double-buy after a break. Mid-Early-Access runs that never saw Side Bag should reread Version 1.0 notes — save compatibility for mid-run EA files does not carry into 1.0 runs.

Active grid versus Side Bag

Location	Items	Effect
Main grid	Artifacts + tablets	Active power, adjacency, Combo Effects
Side Bag	Spare artifacts/tablets/consumables	Inactive until swapped

Never assume bag items still grant passives. Always swap before the boss door, then Q/E preview the final board from Controls habits.

Side Bag workflows that win runs

Exploration kit

Keep mobility, gold find, or XP helpers active while clearing rooms. Park awkward shapes that break rails — see Tablet Combinations.

Boss kit

Before chapter finales:

• Swap sustain for burst if the phase is a DPS check.
• Insert elemental tablets matching Hard Mode modifiers.
• Hold a cleanse Potion or Miracle from Miracles & Potions without clogging adjacency.

Experiment kit

Bank a speculative artifact until its matching tablet drops. Side Bag makes greedy “maybe later” picks safe instead of dead cells.

Priority among inscription purchases

Recommended Sapphire order for many accounts:

1. Survival nodes that keep you alive long enough to earn Sapphires.
2. Side Bag once Home Repair Talents are online.
3. Committed weapon branch offense.
4. Luxury quality-of-life.

Skipping Side Bag to rush vanity weapon nodes is a common reason Chapter 6 feels “unlootable.”

Co-op and Side Bag

Each player manages a private bag. Call swaps in co-op so the party does not enter the boss while someone still has exploration junk equipped. Host disconnect still ends the run — finish swaps before the cutscene, not during.

Mistakes to avoid

• Leaving burst pieces in the bag during the DPS check.
• Swapping mid-combat without a safe room.
• Filling the bag with junk you will never equip — sell or trash from Artifacts logic.
• Forgetting to re-enable a tablet line after a swap (preview Q/E).

Practice drill

1. Unlock Side Bag within your first dozen Sapphire spends after talents.
2. Clear a chapter with one intentional pre-boss swap.
3. Beat a mini-boss using a bag-stored defensive artifact.
4. Enter Chapter 6 with a written bag checklist — sustain, burst, cleanse.

Side Bag is the quietest 1.0 power spike. Unlock it, treat it like a loadout editor, and stop deleting the artifact you needed two rooms later.
