In most cases, unless it was some special monster like Plague Reaper or Thunder Demon, Phantoms always had an advantage over their natural enemies - the number of abilities and thus the number of possibilities.
True, quantity didn't mean quality, and not infrequently that was a disadvantage rather than an advantage, but Phantoms rarely had that problem.
A monster might be an unsuitable opponent for a particular Phantom, but its abilities were not useless.
The military might have many pointless weapons in storage that were either unusable or too weak, but with Phantom's arsenal, with the Evolution Tree, this was not the case.
Each of Phantom's abilities had its purpose, and the Evolution Tree also retained variability.
Thus, it was almost impossible to find a Phantom with all of its abilities focused on amplification, healing, or defense.
Phantoms hunted monsters, so they had to have ways to attack and deal damage, at least one or two.
