Problem with Wait until unit has buff

[Mortimir]

I have an ability based on Shadow Strike that applies a buff called Struck by Fireball. I've removed all damage from the ability and it does nothing but apply the buff for 4 seconds. I then want to wait until the projectile hits the target and applies the buff so I can deal custom damage. The problem is, the buff is applied, but the rest of the effects never happen.

Here's the code:

• Events
• Unit - A unit Finishes casting an ability
• Conditions
• (Ability being cast) Equal to Fireball
• Actions
• Wait until ((Target unit of ability being cast) has buff Struck by Fireball Equal to True), checking every 1.00 seconds
• Game - Display to (All players) the text: You should see this

Is there anything blatantly wrong with what I'm doing? It never gets into the display text action. Thanks in advance!

"Target unit of ability being cast" won't work with waits.

Make variable for targeting unit.
Btw I have never seen action. W8 until unit has buff, does that action exist at all

Use a projectile system, it ensures success.

Thanks guys. I might as well edit a projectile system I already created like MortAr said, I was just trying to see what I could do by adjusting Blizzard's spells.

@HammerFist132 The action is called Wait for Condition, the condition was for unit to have a specific buff.
