If your character would like to make a suggestion about the Tower or request an (able to fit in the Tower) object, they can do so here via filling out the correct form. Note that the Tower may not grant all requests, and it may not interpret requests correctly. There is a note on the suggestion box that says "no more than five requests per month". The characters are free to disregard this and place as many notes in the box as they wish, but only the first five will be considered.
Note that currently there is only a 1 in 4 chance you will receive an item from the suggestion box, although the characters do not know this.
The suggestion box requests are answered on the first of every month.
