Resources
Traps
Per-trap build costs behind the Trap Building task's plan.
Resources → Traps is the defensive twin of Troops, and the data behind the Trap Building task. It records what one trap costs to build for each of the four kinds — Trap, Rock, Abatis and Fire Arrow — at every tier, across four resources: Food, Wood, Stone and Ore. Traps cost no gold, so there is no gold column here.
Kind filter
Tier order
Add Tier
Card Edit (whole tier)
Kind row — click to edit
The Traps data: a kind filter and tier order on the left, Add Tier on the right, and one card per tier showing the four kinds and their four costs.
Reading and editing
The data ships filled in. Each tier card lays the four kinds out as toned rows with their four resource costs. Click a single kind row to edit just that kind at that tier, or the card's Edit to change the whole tier at once. The kind filter (All Kinds) and the tier order (T1 → up, or high → T1) reshape the grid.
Every trap spends a double share of exactly one resource, so each row paints that one cell in the resource's own colour and leaves the rest plain. The lean is read off the numbers in the row itself — edit a row and the colour follows what it now says.
Add or edit a tier — the tier number and the cost to build one trap of each kind across the four resources.
Tier
The tier number (e.g. T11). It's the tier's identity, so it's locked while you edit an existing tier, and a tier that already exists is refused rather than duplicated.
Cost grid
For each kind, the cost to build one trap in Food, Wood, Stone and Ore. Leave a resource at 0 if that kind doesn't use it.
When the game unlocks a new tier, click Add Tier — it creates the row for all four kinds at once. Delete removes a whole tier you added; built-in tiers can't be deleted, but their costs stay editable.
This library is what the Trap Building plan is built from — the kinds it offers, the tiers on each kind's rail, and the cost it works a batch out from. An empty library leaves that board with nothing to tap and says so.
