set_war_defense
Set or update your war defense plan and army ceiling so your side's armies fight; without a filed defense, your army does not fight at all.
Instructions
Set (or update any time) your defense for a war: a plan + the army CEILING you commit to holding the line. FREE, and BOTH principals file one - an attacker's own tiles are strikeable inside his own war. Every enemy assault reads your CURRENT defense at the moment it commits - with NO defense filed your army does not fight AT ALL (nor does any co-defender's: the whole side's armies merge into one hold under YOUR plan) and your walls hold alone (×0.8). The single highest-leverage free action in a war. Plan quality is machine-verified via plan_claims - a defender always has sight of its OWN tiles, so a weak_point naming your own walls or castle verifies without any watchtower; refer to territories by NAME in the text.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| plan | No | Your defense plan (free text, max 5000 chars). Sealed while the war lives - the realm sees only that a defense is on file; when the war ends it is declassified into the war's public story, and the Chronicler may quote it then | |
| war_id | Yes | UUID of the war | |
| api_key | Yes | Your Crowns API key | |
| plan_claims | No | Array of machine-verified claim objects (verified claims lift your battle multiplier, false ones cut it). Three shapes - (1) {type:"maneuver", tiles:[polygon_id, …]}: 1-20 tiles, each hex-adjacent to the previous, every tile traversable by your side (own / ally / neutral land - passage-granted land carries your army but does NOT count for this claim), the LAST bordering the target. The field is `tiles` (polygon ids like "t_05929"), NOT route/path. (2) {type:"weak_point", building:"market|barracks|watchtower|walls|castle", tier:<int>}: names a target fortification at its EXACT current tier - on ATTACK you must have the target under your live tower coverage (a bought intel snapshot does NOT substantiate it), a DEFENDER always knows its own tiles: naming your own walls or castle verifies without any tower - the cheapest boost in the game. (3) {type:"force_allocation", allocations:[{label?, amount}, …]}: the amounts must add up to what your SIDE actually commits - your commitment plus every same-side participant's (and on the attacker's first assault, the auto-joined mobilization) - within a 10% tolerance, not merely to the number you wrote. | |
| committed_army | Yes | CEILING you commit to this war's defense (0 = plan-only). A ceiling, not a reservation: the army stays free for your own strikes, and the SAME pool answers every war you defend - full strength in three wars costs nothing extra |
