set of bone arrow vanes have a base trival of 162
easy trivial table
The trivial list on this page is overly complicated. It would seem that the best way to skill up is to make cheap arrows that might have horrible stats but then make a trivial arrow with decent stats for use. It seems that it would be simpler, or a good addition, to have trivials listed on the "Arrow Components" table so you could just skill up by using all the cheapest components plus whatever single component still gives you skill. This would also be a cheaper way to skill up than to make anything on "The Arrow Table" for skillups. since all but 1 of the 4 components will be super cheap. Sorry, I don't know how to add a new column to this table, or I'd start it out.
