I seem to have both the original one, and the one that you get at max level. Both of them yielded 10 Alchemical Catalyst, and their cooldowns seem to be independent of each other.
Not sure, but I have both on my tailor and enchanter now... possibly a way to increase usage of mats daily? If they did this with eng, bs, jc it would at least let them use the ore from a lvl 2 mine daily.
