Build time and upgrade cost by level
Every upgrade to Watchtower costs food, wood, stone and iron in a fixed 1 : 0.8 : 0.5 : 0.4 ratio, and takes a time derived from this plot's own base of 24 seconds. The curve has two phases: it climbs gently to level 19 — the tier-7 milestone the whole opening is paced around — and compounds harder above it, so the summit costs a real hoard as well as real patience.

What the tower lets you see
The Watchtower gates the quality of your warning, not whether you get one. Without a tower you still know a host is riding at you and when it lands — you simply do not know whose, how many, or what they brought. Each tier peels back more of that fog, and the ladder is short: everything the tower can ever show you is visible by level 5, which makes this one of the cheapest complete upgrades in the keep.
| Watchtower level | Tier | Host size | Attacker's name | Troop composition |
|---|---|---|---|---|
| 0 – 0 | Lookout | Hidden | “an unknown host” | Hidden |
| 1 – 2 | Watch | Shown | “an unknown host” | Hidden |
| 3 – 4 | Vigil | Shown | Shown | Hidden |
| 5 and above | Farsight | Shown | Shown | Estimated by band |
The composition read is an estimate, deterministic per march — the tower reads banners, not muster rolls — split across vanguard, horse, bowmen and siege. Seeing siege in that estimate is the single most actionable thing the tower tells you, because siege is what clears your traps.
