RWWeapons

Item Base Requirements
Runewords can only be made in regular items ( ethereal or non-ethereal), and the socket count must be exact. They cannot be made in magic / rare / crafted / unique / set items.

Melee Weapons include all non-ranged weapons except Orbs. Technically, Wands are melee weapons for the purpose of creating runewords.

Note that the in-game tooltips can sometimes be incorrect since they refer to weapon "super-classes" rather than the "sub-classes" that are relevant in most scenarios.

Staves

 * Wands/Orbs are not part of the Staff sub-class

Maces

 * Scepters are not part of the (Tipped) Mace sub-class
 * Clubs, Tipped Maces, and Hammers are all commonly referred to as Maces, but Clubs/Hammers are not part of the (Tipped) Mace sub-class. To help differentiate the Mace super-class and Mace sub-class, the latter is called "Tipped Maces" instead.
 * Clubs:
 * Club, Cudgel, Truncheon
 * Spiked Club, Barbed Club, Tyrant Club
 * Tipped Maces:
 * Mace, Flanged Mace, Reinforced Mace
 * Morning Star, Jagged Star, Devil Star
 * Flail, Knout, Scourge
 * Hammers:
 * War Hammer, Battle Hammer, Legendary Mallet
 * Maul, War Club, Ogre Maul
 * Great Maul, Martel de Fer, Thunder Maul

General Changes

 * Many weapon runewords can be made in additional bases:
 * All runewords that can be made in Polearms can now also be made in Spears (Crescent Moon, Insight, Obedience, Rift, Infinity, Destruction, Doom, Pride)
 * Claws can now also be used to make Steel, King's Grace, Black, Lawbringer, Crescent Moon
 * Famine can be made in Swords (in addition to Axes/Hammers)
 * Doom can be made in Swords/Staves (in addition to Axes/Hammers/Polearms/Spears)
 * Infinity can be made in Staves (in addition to Polearms/Spears)
 * Spirit can be made in Staves (in addition to Swords/Shields)
 * Insight can be made in Scepters (in addition to Polearms/Spears/Staves)
 * Voice of Reason can be made in Bows/Crossbows (in addition to Swords/Tipped Maces)

 * Unbending Will (from D2 Resurrected)
 * Dominion
 * Mist (from D2 Resurrected)
