Hand-reared dragon.

in war. But for a mage, magic will be much more useful.

For a Warrior: o.

Of course, the warrior has more rage, as the dragon is his magic :). The mage has an advantage: he has real magic that depends not on levels, but on intelligence, which is pleasing. In the end, the mage turns out to be stronger than the warrior: my Amelie currently has an intelligence of 42, and "fire rain" deals 3500-4500 damage :). "Battle Frenzy" can only threaten this at maximum development. But the dragon is also an effective support for the mage :). "Mana Accelerator" helps to restore mana reserves; "Dive Bomb" and "Crushing Blow" also help a little, in particular, to drive enemies into deadly traps :). So the mage has two strong magics, and the warrior has one. But theoretically, a warrior can also have high intelligence. But let's discuss this in another topic :).
