[Instrumentalization] This exclusive feature has always been a love-hate aspect for Beast Masters.
Firstly, the exclusive feature [Instrumentalization] is extremely rare.
The rarer something is, the more precious it naturally becomes.
In the Beastmaster world, some Federations' nobles are very fond of using artifacts that have been instrumentalized from their Guardian Beasts.
The Dragon Rising Federation does not have such a custom, but it can't be denied that the exclusive feature [Instrumentalization], if it can instrumentalize into a usable weapon, is extremely helpful for Beast Masters in combat.
For one, possessing a weapon instrumentalized from a Guardian Beast is akin to using a spiritual instrument in battle, especially in a place like the Battle Network.
Secondly, Beast Masters can use the weapon instrumentalized from their Guardian Beast to protect themselves during combat.
