do the quest line for zero its from 100- 180 or 200 its better to do it turst me i went girding n i regret it.

I believe you still have to do its storyline quests for some skills and link skill.

If you dont want to buy a 2x quest booster like everyone is suggestion i say power through til 120 (or the end of chapter 2, whichever comes first) and head to RnJ til 135~140 + MPE. then DIPQ + MP3 to 160 then get someone to tele u into (or use a VIP rock) second drill hall and grind or leech.

And for the slower levels or when youre bored you can go through the story quests and get the damage bonuses and WP to reset potentials.

Basically after you can leave mirror world after chapter 2, you can follow any generic training guide.

x2 quest booster and finish EVERY QUEST there. I reached lv.180 in 6 hours of playing my Zero

Btw you can't get exp from outside Mirror world until you finish Chapter 2 now

um like just get 2x quest booster and do story and do like 1-2 side missions, But it gets really boring tbh i hate zero i am so glad its over

Quest booster while following the storyline.

I was surprised at how fast I got to 180. At the rate I went I could have used that same coupon on 7 other Zeroes and level them all to 180 before the coupon's expiration.

2x quest booster and just go through the storyline.

Dungeon and quests. Or finish the second act so you can leave, level up to like 130~140ish with Zak, RJ or MPE, then buy a 2x quest card and power through as many chapters as you can.

But I just did the quests (usually got me one level) then ran the fastest dungeon (got me another level, thus unlocking the next set of quests), and did some DIPQ if I got bored past 160ish

I heard the 2x Quest exp in the cash shop speeds it up quite a bit.

And I've seen at least one zero in RnJ once, but I'm not fully sure if they can go there.
