You actually created it at map init and then tried an ability on it?
Just to be sure, show me the trigger.
Well, seems like there's really nothing working. The whole magic immunity is likely corrupted. : /
How many different abilities can the builders and workers get casted at?
I used multiple abilites
Entangle roots as a base
Shadow Strike as a base
Chain lightning as a base
Forked lightning as a base
They all do damage and they all can be targeted at that unit.
