Eterra's Blessing, ardent touch its bugy?

Im trying to use eterra blessing on my companions and cant see any diference.
When I open the minion status and cast directly the skill, nothing happens.

The Movement Speed, Cast Speed and Attack Speed are only for the individual minion that Eterra’s Blessing is cast on.

You will not see any changes in your minion stats, since this only shows global bonuses.

tks so much
