If you don't know the world editor well, then you should learn how to at least make a GUI spell before trying to make triggered abilities. Even if you manage to copy it from someone else, you'll have no idea how to fix anything with it or customize it. The only thing you need to know to make Walrus Punch are dummy casters, flying height, and timers. Everyone likes to code cool spells, but you must start small and then work your way up.
