Tech tree and custom kits

The tech tree (Store then Open tech tree, address /store/custom) lets you research the blueprints of Rust items with gems and then compose your own kit, item by item. It is the gem-powered version of the in-game tech tree.

How it works

1. Pick a server in the top bar. Research and tier unlocks are per server.
2. Pick a tree with the tabs at the top.
3. Unlock the tree (a one-time fee per server per wipe), if it shows as locked.
4. Research blueprints you want. Blueprints go straight into your Blueprint Book.
5. Add items to your kit and buy the kit. Claim it in game with /kit.

Trees

Tab	What it is
Tier 1, Tier 2, Tier 3	The three workbench tiers of the game.
Engineering	Engineering workbench items.
Extra trees (for example Military)	Trees added by the platform and switched on by the community, plus the community's own custom trees.

A community can hide any game tree or switch extra trees on or off, so the tabs you see differ per community. Locked trees show a lock icon on the tab.

Unlock a tree

A locked tree shows "Tree is locked on server. Unlock it to research its blueprints." and an Unlock - N button (the fee in gems). Signed-out visitors see Sign in to unlock. A tree can cost 0 gems; it is then free.

• The unlock lasts for the current wipe of that server. A full wipe of the server resets it.
• Unlocking again is blocked ("Tier already unlocked").
• Fee: set per tree by the community.

How research works

Researching an item:

• Unlocks the blueprint in your Blueprint Book instantly.
• Needs you to be connected to the server you selected when you research.
• Takes gems only once the server confirms the blueprint was granted. If the game refuses (player not found, blueprint already known, plugin missing), your gems are refunded for that item.
• Unlocks every missing item on the path: clicking a deep item shows Unlock - N, the total gem cost of the cheapest chain from an unlocked item to the one you picked. Costs are shown per chain, not per item.
• Resets on wipe. Unlocks reset with the server's full wipe.
• Is closed for 4 hours after a wipe. Trying earlier shows "Researching is on wipe cooldown. Try again in N minute(s)."

Item costs are set by the community (an unlock cost per item or a scrap-based rate).

Use the canvas

Action	How
Move around	Drag, or arrow keys on the focused canvas.
Zoom	Scroll wheel, pinch, + / - buttons, or the plus/minus keys.
Reset view	0 or the reset button.
Item details	Hover (desktop) or tap an item: name, description, ingredients, craft time, gem value, unlock cost.

On phones, selecting an item opens a bottom sheet with the actions.

Build and buy a kit

1. Select an unlocked item and click Add to kit (shown as Remove from kit if it is already in). Locked items show Unlock - N instead; items from a locked tree show Unlock tree first.
2. Open Your kit. For each item use the plus / minus controls to set the amount. Clear empties the kit (with an Undo).
3. A kit holds up to 24 items. At the limit you see "That's the maximum of 24 items for one kit."
4. Check Balance and the total. The total is the sum of each item's gem value times its amount.
5. Click Buy kit - N. If your balance is too low the button becomes Add gems.
6. The kit is written to the server in the background and ready in a few seconds (up to about a minute). Then type /kit in game.

Rules for custom kits:

Rule	Detail
Price	Calculated by the server from the item catalog, never from the page.
Wipes	"Purchased custom kits will not be wiped unless claimed": by default a map or full wipe removes only custom kits you already used; a force wipe deletes all of them. The community can change this.
Cooldown and uses	Come from the community's custom kit template, if it has one.
Failed setup	If the kit cannot be set up in game, your gems are refunded.
Cart	Kept in your browser between visits.

Troubleshooting

Message	Fix
Select a server first	Choose a server in the top bar.
You must be connected to the selected server to synchronize Blueprints	Join the server, then research again.
Server is currently offline. Blueprint sync requires an online server.	Wait until the server is online.
Researching is on wipe cooldown	Research reopens 4 hours after the wipe.
Not enough gems	Add gems from the top bar.
Partial success	Some items were refused by the game and refunded; retry for the rest.
