King of Stone

Towers and walls. Trebuchet gains a projectile for each construction, Quarry buffs every building each year, and Earthworks unlocks plots.

High-difficulty build

Trapper and Trebuchet (Aevean): Trappers have stunned since Patch #30 and gained damage in Patch #31. Trebuchets deal area damage since Patch #29 and fire 1 extra projectile per construction in your kingdom, so fill spare plots with buildings. Aevean drops the Stronghold base and wall plan, which were weakened. Perks: Hunter (longer stuns) and Hurler (extra rocks). Decrees: Dynamites (traps trigger again) and Engineering (double tower damage).
Poison Ballistas (Vao): place Cauldrons beside Ballistas so their piercing bolts poison, 3 stacks per Cauldron level. Take Venom and Distillery (Cauldrons reach diagonals), use Brewer, add walls in mid-game and keep levelling the Stronghold.

Two sources disagree on whether to level the base.

From Builds for every king, where the player guides behind each plan are listed. Run plan for all kings: How to beat King difficulty.
