"As the moon's grasp on the constant grows stronger, so too does its influence on the clouds and tides."
The Lunar Rainforest:
The primary idea behind the Lunar Rainforest is an environment with permanent rain that encourages preparation before exploration, on top of gaining wetness (without rain gear), the unique rain will also give players lunacy overtime, similar to how it works on the lunar island. The resources here could be required to make more advanced lunar gear/equipment/magic items. Maybe some could be used to harness the power of the storm?
I'm not sure if gestalts would be included on this island, but maybe they could be replaced with moon storms that specifically target players with high lunacy? These storms wouldn't have fire spreading properties, but would be a high focus strike, dealing more damage than a regular lightning strike, they persist randomly until the player either lowers their lunacy or flees the island.
A Few item Concepts:
Celestial Effigy
Recipe: 1 x Moon Spore, 3 x Wane Leaf, 1 x Compass(?)
A one time usage item that grants the ability to warp to a player of choice through the power of the moon storm! The effigy could work as a way to get around the world quickly, but the resources for it would be exclusive to the Lunar Rainforest. I'm not sure how it would compare to the Lazy Deserter, though.
Storm Staff
Recipe: 1 x Electrical Doodad, 1 x Cratered Moonrock, 1 x Star Stone
Fires a concentrated bolt of the moon's lightning at a target, counts as electrical damage, damage does not scale with any modifiers, more uses than an average staff. (50 uses?)
Conclusion
Thanks for stopping by to read this little brainstorm exercise! What do you all think of this idea? I personally only made this because I loved the idea of an island that never stopped raining, giving more uses for rain gear outside of spring.
