This cloak was made by churning up a deceased (well checked, not sleeping, honest, no animals were harmed in the creation of this item) turtles shell in much the same way as is used to make paper. Using true wisdom in it's life rather than sheer will power, the turtle manages to survive and it utilises it's shell well to defend itself against attack. Rather unfortunately is that because this shell was turned into a much thinner form it has lost some of it's durability and is left with only a small amount.
