For my fantasy series I am still tweaking the world and one thing i have not really settled on is a magic system. I was wondering what you found interesting about magic and which seems to work best. e.g. in harry potter it seems that there are just random words which causes an magic effect , while others have ancient spells in latin and such. Another thing I was wondering about is wands and staffs cool or unnecessary? or has the great success of harry potter ecspecially the seventh book wands being a large part in this should I try to stay away from them?
