Just a couple short and sweet ideas here...
I think I suggested this before, but anyway:
Remember how the flame sprite for the candle class can be selected? However, as while the Magic Book and Din's Fire also use the flame sprite, their flame sprite cannot be selected in the action tab and they can only use the default flame sprite as seen in this illustration below:

Personally, I think it would make sense to assign the flame sprite to weapon slot 5 for Din's Fire and weapon slot 2 for the Magic book as seen in the illustration below, so that way, we could customize the flame sprites for Din's Fire and the Magic Book by selecting another weapon sprite from the weapons/misc section (specifically a custom flame sprite).

Also, remember how the candle and Din's Fire have the flag 'Don't Provide Light'? Well, on the other hand, as while the Magic book has the 'fire magic' flag, which makes wand magic burst into flames, it does not have the 'Don't Provide Light' flag.

Personally, I think it would be a good idea to add the 'don't provide light' flag to the Book item class, in case the 'fire magic' flag is checked. That would be flag 2 by the way.

PS: Two of these images contains mock-ups of what I think should be done. If I had any knowledge of the code, I would do it myself... Further more, as these are post 2.5 suggestions, I have merged this and the next post into this topic.
