Abbadons shield triggering

[troyboy]

I'm trying to make a spell similar to the shield Lord of avernus uses in dota.

For those who dont no, the sheild takes some damage, then explodes dealing damage.

But mine is a lightning shield, that does the normal stuff that lightning shield does with the immolation effect thing.

But after 20 seconds, i want the shield to explode, dealing damage to nearby units.

Heres the trigger i had, but it didnt work...

Does the dummy unit has enough mana to cast the dummy ability? (looks like you are using a normal ability that is not modified)
