nasty comments aside this is now the 6th rank 5 dagger a dnc can wear:
terpsichore
twashtar
daka
DA parazonium
angr harpe
and now this
sure its a heavier weapon than say phurba, twilight or your standard magians, but for those that dont have a mytic/empyrean and cant be assed to make Daka/para this weapon is a fine upgrade from angr harpe.
while it may be slower than other daggers such as elemental magians, being a rank 5 weapon allows you to be able to reach the next thresh-hold for your standard attacks and of course weapon skills.
mind you this option is only viable if you dont have any other rank 5 dagger (aside from angr) to main hand as this is a poor off hand weapon.
I don't understand all the hate directed at this weapon. I'm not the THF/DNC type, but DPS and attribute bonuses on this harpe make it a formidable weapon. Just because it isn't the absolute best weapon doesn't mean it "sucks".
Its not an 'Awful' weapon, There are simply better options. STR kila for one, as an offhand the new "Onerios' Knife" is pretty hot (Its Crit Dmg+10%, Delay 150, Rather impressive). for THF theres Triplus Dagger as a offhand.
So while you're not exactly gimp for using it, you should work on getting better weapons when you can.
also have to remember (If you're thinking of buying it), sure, right now its less work than Magian weapons, because you can just buy it, but at the same time, Magian Weapons are going to level up with us to 95, and 99, Where as This will not, and will eventually and inevitably become worthless.
So consider that when paying high price for this, It will crash sometime in the near future due to the nature of the game right now.
That being, We're going to 99, this won't be good at that level, Considering the Magian Weapons themselves will likely go past 46 DMG and still maintain their strong boosts to STR, Attack, and their great Delay.
