Can someone edit this spell for me?

[Cris2387]

local combat = createCombatObject()
setCombatParam(combat, COMBAT_PARAM_DISTANCEEFFECT, CONST_ANI_ENERGYBALL)
setCombatParam(combat, COMBAT_PARAM_CREATEITEM, 1497)

local arr = {
{1, 1, 1, 1, 1, 0},
{1, 0, 0, 0, 1, 0},
{1, 0, 2, 0, 1, 0},
{1, 0, 0, 0, 1, 0},
{1, 1, 1, 1, 1, 0}
}

local area = createCombatArea(arr)
setCombatArea(combat, area)

function onCastSpell(cid, var)
   return doCombat(cid, combat, var)
end

  <instant name="vip trap" words="Exevo Gran Trap" lvl="100" mana="500" prem="0" aggressive="1" selftarget="1" exhaustion="1000" needlearn="0" event="script" value="custom/magic prison.lua">
     <vocation id="5"/>
     <vocation id="6"/>
     <vocation id="7"/>
     <vocation id="8"/>
   </instant>

i want this spell to give red swords to the player that uses it and also when someone uses this spell close to the water the magic walls appear on the water so please someone try to fix that too, thank you!
