In this challenge you have to apply a decrease deff debuff on the Force Guardian.

i

I applied more than one time decrease deff on Force Guardian and even on minions that are next to him. 

I don't know what to do when this didn't count I win the round, I look even on other forums about this but didn't find any answers. This "bug" or something is on my main account >Itismethedio< and this "bug" is not allowing me to progres in the challenges.

Here are some screenshots as proof.

Please help me with this. 

Thanks for help and answers.
