What is a Spell for A Whale of a Wand

[Bronsteijn]

What would proc the charm from A Whale of a Wand? The caster spells obviously. 

But would an invocation do? What about a cipher ability? Would a scroll make it happen?

 

I tried the barbarian fear ward and nothing happened, same with the arcane archer spells.

Cipher powers are impacted by Rapid Casting and Farcasting, and can be reflected so they're considered spells; I'm assuming the wand effect doesn't apply to ally-targeted abilities like Soul Shock but would work with Disintegration and such. I'm not sure about Invocations since I don't use Chanters often.
