Skill/Trigger Help

How do you make a spell/triggered spell so that if you cast it, you get these little units that you can't select but follows you, and attack enemies. Just like in Land of Legends II if you ever played it you will notice that the mage has a spell like that, if you do know how to, plz exxplain it thoroughly

If I guessed correctly what you think, then you don't need to trigger it, that's what the "Locust swarm" spell does (it's the ultimate of the crypt lord).

but how would you make the locusts attack with ranged missile

Never Mind

Also,btw, can you tell me how you can make a spell/triggered spell that allows you to summon a unit that cannot be selected, and cannot move, but can still attack.

if you add the ability "Locust" to a unit, it cant be selected. And if you dont want it to move, try to set the movement speed to 0 or make it as a building.
that is what i would do. To get an attack, simply add one ;)

Wait is it possible to make it come out randomly? like 1/3 chance of being lightning, 1/3 being fire, and 1/3 being ice?

Well!? ? ? ? ?

There 2 way to solve ur problem
1-Create 1 locust swarm with [X] level and on the unit summon replace which unit u want just copy locust unit and edit it attack range and model........
2-Create a trigger with dummy spell that will create unit for hero when he use this spell and u have varriable unit type to store many unit as u want then when hero cast spell just create random unit from varriable unit type
