No, because you only have one bonus action - which this ability consumes.

Yes

Quote from chesonisandrew >>

As a druid, my question is can you rampage to attack more than one enemy if you drop each consecutive enemy to 0 hp? For instance, if there were a bunch of enemies with low hp, say a hoard of rats, can I continue to attack one after another if each one is killed by my attack. 

 No you can’t I’m the creator btw

Guys I’m the creator of this homebrew spell [its my first one btw] if you like it go check out my other homebrew magic item: The Staff Of The Bloody Skull and tell me if it’s too of or something

These would be amazing mounts for a pack of gnolls. 

What is the challenge rating?

Cr: 1. Somehow

The perfect mounts/companions for a pack of gnolls, with 1 of the beasts wearing armor for a better armor class, ridden by the pack lord. 

Look up the Dinocrocuta. That's basically what this is.

NO, YOU HAVE TO USE A BONUS ACTION. YOU ONLY HAVE ONE OF THOSE. UNLESS YOU MULTICLASSED TO GET MORE.
