Magic wand of flatness - can decrease cliff by 1 tile, 100 uses (5$),
What if you want to increase? And people could just make 1x1 tile vaults where it goes down 100 tiles around their walls.
Scroll of fast travel - single use only, can teleport you to your mate claim if you know his HS even if you got rights of englishman skill (5$),
Inb4 chief ports to everyone who posts a hearth secret on the forums or ingame...
Farmer pack - some seeds, humus and agri skill for good start (20$),
Decent but the price is off.
Mason/Miner pack - quarrying and simple fences skills, pick axe (20$),
Again price is off
Necklace of bear - protects from aggressive animals for 48-96h (5-10$) (most wanted by newbies

)
Can't see much of a problem with it but sort of pointless since animals can't murder anyways, just less of an annoyance really
Hammer of destruction - removes selected object on your own claim (5$ - 10 uses)
Just raise your phl everything is easy to break as it is atm
Dagger of newbie - glows when Chief¹ is near (5$ - decays after week or two)
Last wish note - single use, after using you inherit kin list from last character (10$)
No because if the person kins you specifically to harass you or if they kinned you to keep you as kill on sight they could just buy this and then continue to have you on KOS/Spam you
Book of the dead - when you got it in your inventory it magically collects names of character you murder (5$)
Encourages murder but is interesting. Shouldn't be a payed for item though.
Your prices seem way off for North American pricing. 14.99 is even sort of expensive for the clothing/furniture now.
