Here I shall be talking about what Will's system was supposed to be.
I will first start by Introducing the world: Boros
Boros is a world where from observation Science as the upper world knows it has not been invented.
The world, since its creation has had an extra element or energy so to speak . This energy was discovered at the equivalent of the Earth middle world's prehistoric era.
From that time on the beings in that world slowly gained the ability to absorb and control this energy.
Multiple beasts evolved the ability to absorb and control this energy directly but those who went on to become what we call humans were not so lucky.
They also gained the ability to absorb this energy but their ability was too weak, so weak that they could barely absorb any energy at all without the help of special catalyst discovered and utilised in the equivalent of the age of renaissance.
Will would have been transferred to the equivalent of the beginning of the medieval age.
In this age 'catalyst technology' shortened to CATTECH had advanced but was only as effective as mid level beasts and was only available to the "nobles".
The plan was to give Will a low grade system that would allow him to absorb energy at the same speed as high level beasts naturally.
Along with an inventory and a shop for all items in presently existing in that world.
The shop would use Mind Points or MP for short.
The MP could be acquired while absorbing energy. While absorbing energy the host would be given the option to divert it to the system to acquire MP.
The host would also be given the necessary basic knowledge ( Language,writing) to live in the world.
This would have been the story of Will's rise to the top if David hadn't 'panicked' and sent him to a high level zone getting the poor man killed.
