Yeah, same here. I couldn't see anything wrong with Athena judging from the video.
The only thing I spotted is that there's nothing moving Athena in her RUNATTACK. Despite its name, setting command or script to move character is optional there.
There are couple problems.
First, summonframe and spawnframe could only work once. You'd need script for multiple spawning.
Second, before spawning anything, you have to make sure to be spawned entities have been loaded also.
