In a thread about replacing the 50 charges of a wand with a die-degrading solution* Genshou mentioned, that in EoMME there is no possibility to create charged items. Is there a particular reason for this?
*Die-degrading is simple: You need only five dice (d20, d12, d8, d6 and d4). You start with a freshly created wand, so you take the d20. Each time you use a charge, you roll with the die. If you get a 1, then you use the next time the next smaller die. If you get another number, then you keep the current die. If you get finally a 1 with the d4, the wand has no charges. This method averages out to 50 charges over the long run and reduces bookkeeping. And getting only 5 charges has only a chance of 1/46080, so a player doesn't need to worry that much.
