Hi
In theory it is possible to equip 2 wands but in reality, that is almost impossible because of this:
In your main hand weapon (left side of "C" panel): you can equip "1-H" or "Main hand" type of wands.
In your second hand weapon (right side of "C" panel): You can only equip "1-H" wands.
Like 99.9% of wands in game are always "Main hand" so they can only be usable as main weapon (left side).
Daggers don't have this problem, they are always "1-H" so they can be used in both hands. Even a copy of the same dagger can be used in each hand.
At the end, the best option due to their atributes is, wand as main hand (left side) and dagger in second hand (right side).
About transformations, there are a few for mage. All new ones give same buffs. All transformation potion you find with these 4 buffs is for mage, just pick one of them.
You can find the pets here:
Here is one of them.
In the future you can also change how the pet look. These ones are not giving atributes, is just a skin. Here:
You can find some more information about how pets work, here:
