imaginei que voces iriam precissar ver o script dessa spellbook

function onUse(player, item, fromPosition, target, toPosition, isHotkey)

    local count = getPlayerInstantSpellCount(player)

    local text = ""

    local spells = {}

    for i = 0, count - 1 do

        local spell = getPlayerInstantSpellInfo(player, i)

        if spell.level ~= 0 then

            if spell.manapercent > 0 then

                spell.mana = spell.manapercent .. "%"

            end

            spells[#spells + 1] = spell

        end

    end


    table.sort(spells, function(a, b) return a.level < b.level end)


    local prevLevel = -1

    local spell

    for i = 1, #t do

        spell = t[i]

        local line = ""

        if prevLevel ~= spell.level then

            if i ~= 1 then

                line = "\n"

            end

            line = line .. "Spells for Level " .. spell.level .. "\n"

            prevLevel = spell.level

        end

        text = text .. line .. " " .. spell.words .. " - " .. spell.name .. " : " .. spell.mana .. "\n"

    end


    player:showTextDialog(item.itemid, text)

    return true

end

Mude isso:

for i = 1, #t do

for i = 1, #spells do

Para resolver esse problema eu peguei o mesmo script de outro servidor vai o script que funcionou para se alguem tiver o mesmo erro .

function onUse(cid, item, fromPosition, itemEx, toPosition)
	local count = getPlayerInstantSpellCount(cid)
	local text = ""
	local t = {}
	for i = 0, count - 1 do
		local spell = getPlayerInstantSpellInfo(cid, i)
		if spell.level ~= 0 then
			if spell.manapercent > 0 then
				spell.mana = spell.manapercent .. "%"
			end
			table.insert(t, spell)
		end
	end
	table.sort(t, function(a, b) return a.level < b.level end)
	local prevLevel = -1
	for i, spell in ipairs(t) do
		local line = ""
		if prevLevel ~= spell.level then
			if i ~= 1 then
				line = "\n"
			end
			line = line .. "Spells for Level " .. spell.level .. "\n"
			prevLevel = spell.level
		end
		text = text .. line .. "  " .. spell.words .. " - " .. spell.name .. " : " .. spell.mana .. "\n"
	end
	doShowTextDialog(cid, item.itemid, text)
	return TRUE
end
