You should have a shield regardless anyway so adding attack is just extra.
For a WK it's less stressful because they're not actually competing with 2h DPS Since their shield skills make up for the damage loss as is. Try to slowly build it up to like, 7-12, And make sure it's 3-lined and you'll be golden. Think of it as a bonus, rather than a necessity.
Better than me trying to answer that question, you tell me how much mesos and NX you have and how much you can get.
But really, a shield is almost the last thing you should be thinking of. It's just there for Shield Mastery.
I always thought Attack on a sheild was necessary. So I should just use a clean shield and focus on my other equipment for the time being?
Messos? Not much(Literally), I just spent a ****load on scrolls and stuff. I have around the 50M mark in pure messo and about 400mish in items, I can get more if needed. None atm, but I might get 30k NX later today.
And, two of my Legendary dragon Carabellas failed(14 scrolls went boom, yay)
Weapon comes first every time. You WILL be using a shield after 120, no matter what, guardian is just too good to pass up. So even a 0 attack shield will be better.
Yes, just get a clean shield. If you really feel like it, get a 3% STR one. But it doesn't need to have attack on it - that comes after you're done with your weapon.
If you do want an attack shield, I recommend getting at least 2 bil or an equivalent of that in NX.
