A free restricted attachment that can go on any hero will never be bad in a post-Forth, The Three Hunters! world. And Round Shield even goes one step further, being attachable to any character in the game, giving it an unparalleled flexibility for archetypes such as Dale. And while it would already be rather decent without any more text than "Attach to a character. Restricted.", its ability is actually really useful, providing a nice defensive boost now and again. The definition of flexibility while giving you a useful effect to boot, Round Shield is a great fit for, well, pretty much wherever you want it.
Rating: 7/10
