Frenzy and Celestial Staff, perhaps all split damage weapons

What you were expecting to happen, and what actually happened?
I was expecting the Land Shark to only gain one attack from one cast of the Celestial Staff.

What happened is that it gained 14 attack. (19 damage Celestial Staff, 5 armor on Shark yielded 14 attack gain.)

What are the steps to make it happen again?
In the Drifting Sands challenge with 4 land sharks, kill all but one, and cast the staff.

Do you have any screenshots or video you want to share with us so we can see the problem? Attach them to your post!
Screenshot doesn’t look to be loading, do I’ll send it to support.

Uploading…

Not only weapons, I noticed that using Rowanne.

I don’t know if it’s a new intended frenzy behaviour or not…

By the way, that probably means that against Barrier, split damage is only reduced by one.
This might actually be the intended effect that ended up having a side effect on frenzy… Dunno.
