Having saved up lots and lots I almost have enough to upgrade to a Staff of Life at the mammon, but the problem is I don't know what to upgrade from! At first I thought it would be Demon Fangs, but they are an 'etc' weapon whereas Staff of Life is a one handed blunt. So would I upgrade from a Tarbar or DF, or something else completely?
The highest shop bought weapon of any type(except demon fangs) will work. Upgrade that to top d-grade and use even exchange to get the staff of life if nessisary. Demon fangs doesn't work because it is the highest d-grade book, and no other d-grade weapons have the same crystal value.
