NPDs

Non-Player Dominions or bots are randomly generated dominions that are spawned prior to OOP to facilitate attacking since inactive dominions are virtually non-existent after adding Click-Through Protection (CTP). Since Round 23, about half of them will automatically train and explore land.

Land Size

NPDs are located in Realm 0 'The Graveyard' along with inactive dominions that have not left protection. NPDs spawn at a human to bot ratio of ~1.74:1.

NPD Distribution
Land Size	Percentage of NPDs
525-600	30%
451-525	50%
400-450	20%

Defense

NPDs spawn with defense based on this formula 120 * exp(0.0058 * [Total Land]) multiplied by a random factor. The random factor for ~85% of NPDs is +/- 10%, but for the remaining ~15% it is +15-20%. Dominions on the lower end of the spectrum will spawn with a random amount of offensive specialists to mask the increased networth of those on the higher end. Every NPD will have an additional 1700-2200 defense incoming during the first 12 hours. The larger dominions are more likely to have Guard Towers, but none of them have walls until later in the round (so no need to castle spy at OOP).

Behavior

All NPDs will actively perform automated actions and grow toward a predetermined size between 375 and 3000 acres. Each NPD has around a 1 in 3 chance of 'logging in' each hour. They will build barren acres, cast spells, train defense, train spies/wizards to a 0.05 ratio, invest, and explore (no sooner than 12 hours after OOP). They will cast their spells any time they drop below 4 hours remaining, therefore it is rare that they drop off, but not impossible. If they recast, it is around 30 minutes into the hour. Each NPD is limited to exploring 12 acres in a single hour and between 36-47 over a twelve hour period. NPDs will train defense up to the following formula, which is then increased by 2% each time they are successfully invaded.

Post-OOP DPA Formula

(-0.0181 * [DaysAsFraction]^2)) + (2.5797 * [DaysAsFraction]) - 4.1725

Additional DPA to phase out over first 10 days

max(0, 5 - [DaysAsFraction]/2)

Expected Land Size Multiplier

[Land] / (40 * [DaysAsFraction] + 410) (capped between 0.8 and 1.2 and multiplied by the DPA above)
