What is new in the world this patch
At Account level 150, reset a level 150 skill to earn Vow Points, then spend them on a tree of permanent bonuses. Progress on every other skill is untouched.
A fief that stays solo can make a permanent choice to cut all fief costs and raid enemy stats by 70%. Once taken, nobody can ever join it and it cannot be undone.
Forge and Merchants contracts build standing. Higher standing pays more, unlocks bigger jobs and drops bonus caches. Posting contracts earns Patronage, which discounts your posts and boosts your caravans.
Giving from your inventory now earns Account XP, and fief reserve gifts earn the fief Renown. Both scale with the value given, and the panel shows what you will earn before you send.
Upgrade costs now ramp 8% per level from level 1, with clean round prices. Spoils of War also adds +50% increased raid bonus loot per level.
Empower is friendlier now. The chance starts at 15% and rises 15% per failed try, with the sixth try guaranteed. The tooltip lists the Azurite cost of every try.
Every system, cost and formula is documented. Read the Wiki.
Knightfall Idle places you in a persistent medieval world where nothing you do is wasted. Chop wood, mine ore, fish the rivers, fight for loot, and process it all into gear, upgrades, and wealth.
Raise a kingdom from a single castle to a thriving settlement. Found or join a fief and hold it through sieges. Give to The Realm and every player on the server benefits. Trade on a living auction house, take guild contracts, and roll trinkets into powerful builds. Chase achievements, earn ranks, and climb the leaderboard. Every cost, chance and formula is documented in-game. Nothing is hidden.
The world does not pause. While you are away, your kingdom grows, caravans arrive, and new decisions await your return.
