Nox Beta[]
It is unknown if the beta still is kicking around. However, some elements that were not present in the final release are found within some sources like the trailer and the game files itself.

The Conjurer's summons being composed of an Ogre Lord and two spell bombers.
In the trailer, there seem to be a variety of gameplay content not found in the game released. The first one being that the conjurer could summon eight small beasts, four medium, or two large.
Another strange is how the Lightning Staff worked in the beta. In the trailer, the wizard uses the lightning staff against a Vile Zombie in the way that one would use a Fireball Staff.
The Wizard using the lightning staff to fire lightning projectiles.
