Spell which needs item for Casting

[SeoxTard]

hey guys..
i found this spell here on otland

local combat = createCombatObject() 
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_GREEN) 
setCombatParam(combat, COMBAT_PARAM_AGGRESSIVE, false) 

function onCastSpell(cid, var) 
    local config = { 
        promotion_lvl = 1, --standart promotion 
        outfit = {lookType=145, lookHead=124, lookAddons=1, lookLegs=45, lookBody=11, lookFeet=87} 
    } 
    doPlayerSetPromotionLevel(cid, config.promotion_lvl) 
    doCreatureChangeOutfit(cid, config.outfit) 
    doCombat(cid,combat,var) 
    return true 
end

 <instant name="Promotion/Outfit" words="exana hur" lvl="20" mana="0" selftarget="1" exhaustion="1000" needlearn="0" event="script" value="sip.lua">
		<vocation id="1"/>
	</instant>

how do i change it that it needs 2 Shields/swords or whatever to cast?

Try this:

local combat = createCombatObject() 
setCombatParam(combat, COMBAT_PARAM_EFFECT, CONST_ME_MAGIC_BLOOD) 
setCombatParam(combat, COMBAT_PARAM_AGGRESSIVE, false) 

function onCastSpell(cid, var) 
    local config = { 
        promotion_lvl = 1, --standart promotion 
        outfit = {lookType=23, lookHead=124, lookAddons=1, lookLegs=45, lookBody=11, lookFeet=87} 
    } 
    if getPlayerItemCount(cid, xxxx) >= 2 then 
    	    doPlayerRemoveItem(cid, xxxx, 2)    
    	    doPlayerSetPromotionLevel(cid, config.promotion_lvl) 
            doCreatureChangeOutfit(cid, config.outfit) 
            doCombat(cid,combat,var)
    else
            doPlayerSendCancel(cid, "You need 2 items to cast this spell.")
    end
    return true 
end
