Hi guys,

I would like to edit some spells on my server so that they are only cast when a player is using a specific item, for example:

The player can cast a XXX spell if he uses YYY on the item.
YYY item - item for each profession
can be used every X minutes (exhaust).
Can I do it in lua under 7.6 xml?

Lua: 
local combat = Combat()
combat:setParameter(COMBAT_PARAM_TYPE, COMBAT_PHYSICALDAMAGE)
combat:setParameter(COMBAT_PARAM_EFFECT, CONST_ME_HITAREA)
combat:setParameter(COMBAT_PARAM_BLOCKARMOR, 1)
combat:setParameter(COMBAT_PARAM_USECHARGES, 1)
combat:setArea(createCombatArea(AREA_SQUARE1X1))

function onGetFormulaValues(player, skill, attack, factor)
    local level = player:getLevel()
    local min = (level / 5) + (skill + attack) * 0.5
    local max = (level / 5) + (skill + attack) * 1.5
    return -min * 1.1, -max * 1.1 -- TODO : Use New Real Formula instead of an %
end

combat:setCallback(CALLBACK_PARAM_SKILLVALUE, "onGetFormulaValues")
function onCastSpell(creature, var)
    local weapons = {2321, 5342}
    local shields = {6391, 2523}

        local slotWeapon = CONST_SLOT_LEFT
        local slotShield = CONST_SLOT_RIGHT
        
        local playerWeapon = creature:getSlotItem(slotWeapon)
        local playerShield = creature:getSlotItem(slotShield)
        if playerWeapon and table.contains(weapons, playerWeapon:getId()) then
        if playerShield and table.contains(shields, playerShield:getId()) then
            return combat:execute(creature, var)
        end
    end

    creature:sendTextMessage(MESSAGE_STATUS_SMALL, "You need a special weapon to cast this spell.")
    return false
end

Probably won't work in your engine but you can check

I don't understand exactly what you want
Do you want a spell that can only be used if you use a specific item?
What I don't understand is how it can be used more than once and why?
I can help you if it's like a quest whoever gets it can cast the spell
Whoever does not do the task cannot use the incantation
What do you think?

I just wanted to do so that after using the item it uses a XXX spell. If that can't be done in LUA, then there might be a mission after which we can use the XXX spell.
