[Suggestion] World bosses affecting their region

Demostrathe

Not sure if this will be a mechanic implemented or not as i havent coped enough in scanning the wiki but if it isnt i think it would be a cool idea if a world bosses death for example after killing a earth dragon because their blood effected the dirt or something made special type of flowers,herbs or other resources spawn for a limited amount of time

Nice idea, or perhaps that the relevant resources spawn in unusually high grade and increased quantities.

The idea in itself is genius: Make Worldbosses into open world events revolving around them!
Let's stick to your example of the Earth Dragon:

• When it spawns it first starts building a lair, by either (A) making a cave in a nearby hill/mountain which causes quakes that scares away nearby animals and wakes up rock elementals nearby or (B) sapping life energy out of the nearby forest to grow a giant nest out of vines, thick like trees which results in herb drops and wood quality nearby decrease for some time.
• If left alone after some time things will somewhat normalize again, animals return and rock elementals go back to sleep
• The new lair could attract NPC plunderers to the area that try to steal resources from adventurers, leading to Caravans in the area now having an increased risk of being attacked by NPCs
• On kill the wodden dragon nest could become a temporary dungeon full of wood elementals formed from the leaking life of the dragon, they drop superior quality wood and herbs; the death of the cave dragon could cause the remaining rock elementals to move in and claim the cave for themselves, turning the dragon remains into crystals and other mining lodes all around the cave. At some point the elementals will shut the crystal cave off to the outside world.

It's possible considering that they can affect the area they spawn while alive. Same thing but backwards potentially.
