How do you turn off Zhelm's effect?

I believe that some NX capes can cancel the effect. My brother has the Tania capes that people got for free and, with the whole set, his Zhelm doesn't have an effect right now. It's just a hat. So try some sort of flashy, tania cape like cs effect item?

Best bet is to use invisible hat/ cs hat.

That's because the cape gives the effect of the flame wings, thus cancelling out the zhelm effect.
