Hello.
You didn't specified much, so i'm not sure what you need, so i will post a script that will simple cast energy wave.
if cancast() and mp() >= 250 then
cast('exevo mort hur')
wait(1000)
I'm not sure if you need this script to hunt, if so, unfortunately, energy wave script is complex because that would also depends on Targeting (if you are using it) to find and reach a sqm that you can dmg monsters using energy wave. If that's what you need, i'm sorry but not happening for now.
This script will use a mana fluid that's on floor on player's location, so it will use on your character.
local MF_LOCATION = { X = 12345, Y = 12345, Z = 6 }
local PLAYER_LOCATION = { X = posx(), Y = posy(), Z = posz() }
_useitemon('mana fluid', PLAYER_LOCATION.X, PLAYER_LOCATION.Y, PLAYER_LOCATION.Z, ground(MF_LOCATION.X, MF_LOCATION.Y, MF_LOCATION.Z))
