Made as lvl 17 to 18 getting around 600ish rank xp, easy to make with preserve and maker muse. Had a handfully of blowouts but worth it with the amount of shards you use is worth it.
Also, as a little side note you can sell to npc for 51 gil or save to make throwing hatchets... my pocket just got the tiniest bit bigger.
