How often can a bucket be used to revive a hero?
This morning I revived the hero with a bucket. In the evening I also wanted to revive it but the server did not allow; I checked on the computer and in the application on the phone. Also in the browser on the phone. The computer did not help F5 or cleaning cookies. I had to spend resources to revive the hero.
I haven't found any information on how often the bucket can be used on the Wiki.
