【4E】机关人是否可以装备嵌入式盾牌，空出两手？

[业问]

最近在一个论坛看到一篇文章说机关人可以用嵌入式盾牌，然后空出两手。原文如下：

Shield:You have two free hands even when using a heavy shield, just beautiful. There is no downside.

十字弓也能单手装备（嵌入式）：

Weapon:One-handed weapons are fine; a crossbow that only takes one hand is useful. Two-handed weapons are unclear, whether or not they become one-handed is up to your DMs interpretation, but they definitely have a -2. Even if they do become one-handed, they still aren’t good.

各位达人看看说得是否有道理？

   大概是这类东西

A component doesn't take up the magic item slot of the same type, unless it is a magic item that goes in that slot

这跟magic item又没关系……

我没记错的话书上写的是重盾算轻盾，没说别的，也就是轻盾还算轻盾

拿重盾时可以多hold一个东西而以
