[Spell] Orb Spells

[Edge45]

What I plan is an ability that when attack(melee), lightning shoots out from the sky and strike each enemies in the area and slow them, Its similar to DOTA: Admiral's spell Tidebringer,

The tutorial "Passive with Cooldowns" look like its how the Tidebringer was made, so I created a custom Orb spell, and its Effect ability is Thunderclap (with some changes with the FX, and attachments), then I tried it
here are some images

Now, it doesn't work, the effect ability doesn't activate, need help and info's, I suck at these things

*In case, here's the map, so you will see how I made the spell and know more infos*

that orb effect spell only works with singe target specice target spells wont work with thunder clap and ect *might with flame strike never tested that one* but mainly things like fire bolt storm hammer death coil ect
