Before reading all of this down below, I ask you something. Please, for the love of God, do NOT tell me that I should try another build like this or that, or I should put some of my stat points into SPR, or any other stats, this is the build I desire, and I wish nobody wouldn’t tell me how to play my own character. It’s clearly not the topic here. If you still want to do otherwise, I suggest you to leave, and comment that on another post.
Since we got that out of the way, yes, I’m a Full DEX Archer, I find grinding hard, those with the same build would probably feel me. SP potions are useless to my character, imo. The cooldown is too long, whether it’s a small or a big SP potion, my SP always runs out fast, and the cooldown wouldn’t even finished yet. My basic attack is ridiculously low, below 100, because I literally did not put any of my stat points to STR. So while grinding, I have to wait for my SP to raise back again, and it makes me level slower. My Max SP is about 600++. Currently lv. 72.
So what I’m trying to ask you, is there any good equipments I can find and use? I mean like, equipments that raises your SP Recovery up? Or anything else, other than equipments? Any pills that can raise your SP Recovery faster for a few moment? There should be something like those, since the other MMORPGS that I’ve played had always have them.
Please also suggest 75-level equipments for future use?

So I can better understand your situation.
