Thoughts Regarding the Number of Attuned Items
Officially, someone can only attune three attunable magic items. I've been getting into arguments with my players regarding this restriction. They believe that this is too restrictive, while I maintain that the reason for this restriction is to maintain bounded accuracy and prevent the group from hoarding magic items and growing too powerful.
I would like to know the thoughts and ideas of the community around this restriction. What are your experiences? What are some alternative suggestions? Is it unbalanced?
