This couldve been mentioned in a different way but an idea i was thinking about today was a kingdom song like how we have mining song that uses kingdom authority (gives us more to spend on) to cast and lasts a certain period of time and has a cooldown effect like a month etc. Basically we have a few songs that do different things that last for a day or a few days thats sort of like festivals for the kingdom. For example we could have a songbird Festival where swans magpies ptar eagles etc all spawn a hell of alot more etc and others for animals or foragables.
Potential songs (festivals)
Festival of the ferioucious- Increases the spawn of aggresive animals like bears,boars,wolverines,wolves, slimes, mammoths and eagle owls.
Festival of the druid - Dryads, butterflies, dragonflies,fireflys,ladybugs and other simple curiosity creatures spawn more and better quality.
Wanderers Luck -forageables and rare forables spawn more and better quality
Loki's Day of peace- random things spawn anywhere bears in bases mammoth in a mine etc whatever jorb thinks would be funny.
I would say a war-cry or town-crier buff for during sieges i think that's been mentioned as a buff to a kingdom to boost defenders as in anyone whose hf is in the kingdom lands.
One final idea on top of this, Let us create iriminsul or monoliths (perhaps a npc has a chance to become one from a rare hard quest) or some sort of kingdom wonders as right now it looks like alot of kingdom buffs will never be 5/5 for anyone because they require like 10 monoliths and only 2 -4 on a island.
