More so than cursed items, I am trying to put together a set of rules for a campaign where the characters are the normal player races and their opponets are magical races; i.e. undead, aberrations, etc. What I am trying to come up with is an effective way for the characters to combat them. Firearms, Old West era, were suggested as a possible equalizer, but I worry that they may need more. However, this does not, necessarily give them the ability to destroy certain enemies who are only harmed by magic and/or specific things. It would force the players to be more resourceful, and I am always trying to get them not to do any meta-game thinking, but I worry that they will not be able to stand a chance against more powerful opponents.
Furthermore, I am also in debate as to how the general character creation should be set-up. There has been talk about using the standard classes listed in the core-books and supplements, but that has been countered by using the generic classes from Unearthed Arcana and expanding the list of Class Bonus Feats to include any of the class features available, although some may require prerequisite Class Bonus Feats and the like.
Thoughts?
