石器里没啥可讲，提升人物抗性的道具，道具代码设定好字段即可，字段地，水，火，风分别代表地水火风的抗性，全则是四项抗性一起增加，可参考此代码写魔法熟练度的道具

function kangxing(itemindex, charaindex, toindex, haveitemindex)
	local data = item.getChar(itemindex, "字段")
	local type = other.getString(data, "|", 1)
	local value = other.atoi(other.getString(data, "|", 2))
	local typefun = {"", "", "", ""}
	if value > 100 or value < 0 then
		char.TalkToCli(charaindex, -1, "抗性值错误，请联系管理员神奇的牧羊人", "红色")
		return
	end
	if type == "地" then
		typefun[1] = "地魔法抗性"
	elseif type == "水" then
		typefun[2] = "水魔法抗性"
	elseif type == "火" then
		typefun[3] = "火魔法抗性"
	elseif type == "风" then
		typefun[4] = "风魔法抗性"
	elseif type == "全" then
		typefun[1] = "地魔法抗性"
		typefun[2] = "水魔法抗性"
		typefun[3] = "火魔法抗性"
		typefun[4] = "风魔法抗性"
	else
		char.TalkToCli(charaindex, -1, "字段错误，请联系管理员神奇的牧羊人", "红色")
		return
	end
	for i=1, 4 do
		if typefun[i] ~= "" then
			char.setInt(charaindex, typefun[i], value)
			char.TalkToCli(charaindex, -1, typefun[i].."达到"..value.."%", "黄色")
		end
	end
	char.DelItem(charaindex, haveitemindex)
end

function main()
	item.addLUAListFunction( "ITEM_KANGXING", "kangxing", "")
end
