What gear does the Egg Heist shop sell?

Gear you take into a run is gear you can lose: if you die or faint during an Egg Heist run, your carried items, your backpack and your equipped gear all go with you. Every purchase from the Equip tab is a stake in the next run, not a permanent upgrade.

The backpack is the piece most players buy first. It costs 5,000 coins and adds carry slots, so you can haul more loot out per run. Extracted loot is mostly worth what it sells for, so more slots means more coins coming back to the shop. The defense unit keeps you alive longer, and staying alive is how you keep the backpack. The attack amplifier helps you in fights.

Durability and repairs

Egg Heist equipment such as robots and amplifiers wears down and has to be repaired, and repairs cost coins. Repair between runs, outside the dungeon, where it is cheap. Repairing mid-run costs more.

The shop's currency is earned only from Egg Heist and goes by several names, including Eggshell Coins and shell coins. It is the same currency you spend on talent nodes, so money spent on gear and repairs is money not spent on your talent tree.

Keys are sold separately

Keys are not on the Equip tab, but you buy them from the same vendor before a run. The shop sells door keys, the Sanctum key that opens sealed reward rooms in the Sanctum, and a Gilded Key at 100,000. Keys can also be bought from an NPC trader inside the dungeon or found in loot boxes.

Not settled: The facts give a price only for the backpack. The defense unit and attack amplifier have no listed cost, and there is no list of tiers or variants for any of the three.
