I DM a 5e session, and I recently gave one of my players "Gloves of Missile Snaring." Naturally, one of his first questions was "what can they block?"
By RAW, they affect "ranged weapon attacks." In most cases this is is pretty simple - it blocks arrows and bolts. However, the situation becomes more complicated quickly. Here are some examples:
... javelins? By RAW, these are ranged weapon attacks, so yes. The problem here is that this opens the door for all thrown-melee weapons. Can one block handaxes or hammers that are thrown? Improvised weapons, like a chair tossed at you in a bar fight?
... ballista bolts? By RAW, one would assume these count as a ranged weapon attacks, so yes, but seriously?
... boulders? By RAW, I'm not sure what this would be considered, but if the logic of "it's a projectile and it's being thrown at me" applies to ballistae, then why not boulders?
It's also important to note that these gloves do not work like the similar Monk ability, as they do not allow a user to throw the items back. This implies to me that, despite the name, the gloves work more like "swatting" rather than "snaring", and this too indicates that they may actually reduce damage from items as large as ballista bolts.
So I turn to the RPG-SE community for answers. What are the limits of Gloves of Missle Snaring?
