Quick! Explanation: I was perusing the wiki when I came across this tag: TEC_WBLOCK_3 - Shield
Now then, I went back and looked at all of the melee weapons available, none of which have this tag. To me this means an item would be used in a block, preventing all damage (assuming up to a threshold) if successful.
some items come to mind as a shield:
[li]Kitchen cabinet door[/li]
[li]Antique shield (Medieval)[/li]
all of these items could add a maximum threshold of damage, some being more durable than others as well as adding different encumberance values based on weight and volume
I could post theoretical values for every item that could be considered a shield and their effects and what not, but I just wanted to get some feedback on this to begin with
