Items work in inventory
Let the ability of some items also work in inventory instead of only in hand.
Items that can be affected:
Firestone: Fire protection, friendly Fire Mage
Evil eye:seeing invisible objects
poop stone: nearby monsters poisoned
thunder stone: electricity protection,friendly Electricity Mage
Water stone: underwater breathing, fast swimming
wand stone: edit wand at anywhere
Sun seed: all-seeing eye
It didn’t change all the in-hand‘s ability, such as thunder stone’s discharge and poop stone poisoning yourself.
