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\$

Improvised Weapons

Some improvised weapons are 'items-at-hand', never intended to be weapons, such as the list from the rules given in Mars Plastic's answer: "broken glass, a table leg, a frying pan, a wagon wheel, or a dead goblin."

However, other objects are intended to be used as weapons, that is, designed to damage creatures, and still count as 'improvised'. Things like Holy Water, Thrown Oil, and Alchemist's Fire are "treated as an improvised weapon". The Weapon Master Feat does not allow one to gain proficiency in throwing oil flasks, for example.

Natural Weapons

Natural weapons are the parts of a creature's natural form which are made to be used as weapons, "such as a claw or tail spike". They are the attack mode accessible to a druid in just about any of their wild shapes. Note that wild shape permits the druid to "retain the benefit of any features from your class, race, or other source and can use them if the new form is physically capable of doing so." Here, 'other source' would include Feats, so if the Weapon Master feat allowed proficiency with natural weapons, it would permit a druid with the feat to gain proficiency (and use their own proficiency bonus) with specific natural weapons, such as claw and bite, that they might use while wild-shaped. However, by limiting the choices to simple and martial weapons, this is not an option for the druid.

Neither would the Weapon Master feat permit a PC race with natural weapons (such as Aarokokra, Centaurs, Leonin, Lizardfolk, Minotaurs, Satyrs, Tabaxi, Tortles) to gain proficiency in their use.

Siege Weapons

Besides literally having 'weapon' in their name (they could, after all, have been called siege engines), we know that siege weapons count as a type of weapon from the description of Daern's Instant Fortress, which says (DMG 161):

The roof, the door, and the walls each have 100 hit points, immunity to damage from nonmagical weapons excluding siege weapons, and resistance to all other damage.

What is not clear, however, is who makes the attack roll for a siege weapon - the weapon itself as an object, or one of the crew, albeit without a proficiency bonus. In a game where one of the crew makes the roll, Weapon Master cannot grant proficiency with a siege weapon to allow a crewmember to add their proficiency bonus to the siege weapon's attack roll.
