Hello Again,
I got few ideas for items, maybe someone will find it useful.
1) in Long worlds, for example in my world where I have 7300+ days, I have too many Bone Armors, Shadow Thuribles and Bone Helms and i don't even need that many. Now When there is added New Boss on Lunar Island I used most of my Bone Helms, but still Im Left with many Bone Armors and Shadow Thuribles.
For That I have two Suggestions. First, make thoose items tradeable with Pig King for random gems or gold. Second, much higher durability and Stun Resist chest armor. Recipe for Example: Bone Armor, Thulecite Suit and maybe something else. Maybe even Iridescent gem which has only two uses for third igredient.
2) Item which calls rain. I remember there was discussion about this already awhile ago and I dont think what happened, but it will be very useful item, for summer and mostly for boss fights.
3) Buildable Pit, which deletes items you toss in. I know we all use Lure Plants for that, but Pit would be more better and easier. Also I don't know if this is fixed or not, but Lure Plants don't grab Walter's Slingshot, maybe because I had ammo within or they just dont want it.
4) Last, but not least! Upgrade for Telelocator staff, which will allow you to teleport things which you normaly can't. For Example Wormholes, Florid Postern and Spawn locations for Few Bosses, such as Bee Queen, Klaus, Moose/Goose nests. Sometimes there are wormholes which lead only few tiles away from another, but with this item you can fix it. Another good thing for this item, you can teleport one to Lunar Island for quick travel, since there is new boss and you will be spending much time there. Only 3 Uses for staff and recipe for example: 3x Telelocator Staves, 3x purple gems or 1x Iridescent gem and 3x Living Logs.
