I wanted to make a powerful Berserker without making him too powerful from the current outset due to fears of idolizing a fanmade character (even if that character is based off of a historical or fantastical figure) and accidently making a "mary sue" so to speak.

The reason why I gave the Berserker a reality marble was becuase: 01. I was really stripping the poem and play for details. & 02. I wanted to create a character who's strength relies on territory, which is handy if your a master and you want to know if anyone's out to assassinate you (which they are) and you want to have at least a safe haven of sorts.

The downside to this however being that using all that Prana to claim and create a territory as well as using Noble Phantasms and god knows what other abilities, ontop of putting up with the natrually draining status quo of the Berserker class is extremly dangerous and unhealthy. Realistically unless the master is superhuman or inhuman, their going to be constantly hooked up to a lifesupport machine in a hospital relying on the Servants abilities within a territory while being unable to defend themselves.
