Would suggest that if your any mage job to get this club asap. Until 51 when you can get a dark staff, this is will be a primary source for mp recovery.
The problem with the high mana wand is it must be on constantly for the +4hMP and thus you cannot switch it out for clubs that give int/mnd bonuses.
Edit: I mean the above comment for blu mainly
Problem with High Mana Wand is that you have to buy it (or multiples if you run out of charges) and it's a much later level. This is free, and Lv10. This also lets you use the 5 INT Solid Wand vs. 4 INT High Mana.
