I'm running a traditional D&D 3.5E game. One of my players, a Ftr/Wiz/Eldritch Knight, uses a halberd as his primary weapon. He wants to know if he takes both the Craft Magic Arms & Armor feat and the Craft Staff feat, could he create a halberd that could be used as a staff with charges?
While I'm a firm believer that anything is possible in D&D, my short answer to him was no.
My longer answer was that such an item would be contrary to the spirit of the rules when it comes to distinct weapon categories as well as class weapon proficiencies. I accept that his character is both a melee fighter and a spellcaster, but that also doesn't allow the two distinct item creation feats to somehow blend together and bend the rules about how halberds and staffs (staves?) work or get created. I am, however, willing to hear his arguments and if he can devise a reasonable justification for how to do it (and pay whatever in-game costs necessary) I'm open to the possibility.
My question is: Are there any precedents in the official, published materials from Wizards of the Coast for creating such an item?
