I was reviewing the 2017 PHB Errata (v1.22) and I saw something interesting. Under Feats, it says for Weapon Master

the chosen weapons must be simple or martial.

What does this mean? Aren't all weapons simple or martial? What weapons are there besides simple or martial? Is this just a wording mistake?

The PHB mentions Improvised Weapons, which do not necessarily belong to either category:

Sometimes characters don't have their weapons and have to attack with whatever is at hand. An improvised weapon includes any object you can wield in one or two hands, such as broken glass, a table leg, a frying pan, a wagon wheel, or a dead goblin.

Often, an improvised weapon is similar to an actual weapon and can be treated as such. For example, a table leg is akin to a club. At the DM's option, a character proficient with a weapon can use a similar object as if it were that weapon and use his or her proficiency bonus.

Natural Weapons (such as the Lizardfolk's jaws) are also a thing, and according to Jeremy Crawford they too are neither martial nor simple.

As enkryptor mentioned, some monsters use weapons that are not explicitly categorized.


There are weapons which are usually not available for player characters.

Some examples are:

  • A Grimlock's spiked bone club
  • A Kuo-toa's pincer staff
  • A Redcap's sickle
  • A Chain Devil's chain

You can still find such a weapon in your adventures, but Weapon Master wouldn't work with it.

    \$\begingroup\$ @Gnudiff Neverwinter Nights was based on 3/3.5e D&D rules, which did indeed categorise weapons as simple, martial, or exotic (you can read about this in the 3.5e system reference document here). \$\endgroup\$

    \$\begingroup\$ @enkryptor +1 for awesome monster weapons, but can you explain why these would not fall into either simple or martial? Just because they are not listed on the PHB weapons list, it does not mean that they couldn't be classified as either a simple weapon or a martial weapon. Just a thought. \$\endgroup\$

    \$\begingroup\$ @Orc'sPlunder they could, but they aren't. At least I don't know any official source which does that. \$\endgroup\$

    \$\begingroup\$ The weapons table in the PHB simply shows "the most common weapons used in the worlds of D&D". It is not an exhaustive reference, by its own admission. \$\endgroup\$
