Increased Attunement Slots - 4

This feat is used to enable the Homebrew rule that makes your available Attunement Slots equal to your proficiency. Currently, DNDBeyond only allows for a set number of Attunement Slots, so a different feat will need to be added to replace the custom feat each time Proficiency increases, ie, there will need to be a custom feat for 4 slots, another for 5 slots, etc. 

Each time the new Proficiency is achieved, the new feat will need to be added and the old one removed.
