Transformation [5]
The spellcaster transforms into an animal of their choice. All stats are doubled compared to "standard" animals. 100.
King of Beasts [5]
The character gains a permanent animal companion and is able to command animals.

Do the original character stats affect the form of the animal in any way? Can spells be used in animal form? Does the companion have different stats than "standard" animals and also have stat bonuses/is it an "enhanced" version of a regular animal?

What is the damage and range of crossbows with longbows?

IV. Damage to paralyzed and immobilized enemies is increased by 1.5 times [3]

Is this ability intended solely for ambushes, rosharians, builds with something like arcane magic, and team play? Because without such resources (or some special crossbow with additional attacks), the crossbowman cannot take advantage of this bonus on their own.

Sleight of Hand [5]
Reload -1 turn

What is the reload parameter for a medium crossbow?

Maiming Shot [3]
Accuracy -20%, target loses 25% of its current accuracy and dodge values
Headshot [3]
Accuracy -50%, damage (final) +200%, +30% armor penetration

Does the minus apply to the base accuracy or the final accuracy? Can these abilities be combined?
