I meant, Lethargy’s aoe is small compared to Earthquake, reallistically if you can lethargy only 3/4 targets its really slower than rely on overkill without Lethargy and do 8.
Thx for the input on Novaha Annex, i’ve tested it, looks like respawn is also 2 minutes for the 3 camps. Sounds viable option if Magic Missiles overkills them, i’ll add this into original post.
Oh nice, i didn’t even tested it i thought it was like basic attacks, thx for info i’ll add it.
Mine is 8k/100k as fletcher. Didn’t do it at early lv coz of lacking knowledge in this game.
As a 179 fletcher c2, barbed arrow with 2h bow against flying is a good method too. I can do overkill at my level range with 0cd. I won’t stop progress my adventure by grinding overkill to clear this achievement. I will collect my overkill point while doing my adventure along the ways.
Level 33 and still at 15k kill count. I wonder if I can reach 100k before reaching 40.
Another tip:
Don’t turn in 2nd and 3rd purifier so you can warp back and forth between the two. The purifiers are near the raflower spawn spots.

it’s my 5th day in this cave (my fellow guildmates said i have no life for doing this lol)
each lvl up decrease my overkill percentage by 3% (Energy Bolt lvl 4, from 107% to 104%)
attribute will help in here
fun fact : my 179 hunter c3 friend able to overkill raflower lvl 16 with his pet (rush dog, 225% overkill), even able to overkill with barrage lvl 5, but ONLY if he is in the same party with me
EDIT : got the title 8 days later, 13 days had been spent inside the cave
start at lvl 16 and finish at lvl 39
the reward for this achievement is pretty dissapointing, you got nothing from the title (except the pride of using it of course lol), the loots pretty bad either, i only got 10 Raflower Gems, 2 Bat Gems, 30 Red Gems, 13 Blue Gems, 9 Golden Anvils, 2 Mithril Ores and a lot of junks that only worth selling, my silver is around 480k right now (you can get a lot more with all the time spent in dina bee farm or somewhere else)
but tbh i had some fun doing this chore, i’ve met a lot of new people passing this cave and wondering about myself killing raflowers, after i explain my reason mostly people goes surprised and shocked (even some guys called me crazy haha) but they still support me in the end, i really think this is the best part when seeking for this achievement
last thing is i hope IMC will give some effect on the title someday, that would be great reward in return
Aww…wish i had known this earlier D:
I’m lvl 245 wiz now …ugh…
I don’t even have meteor since im necro… ._.
Well…perhaps in a future IMC will think of this and make some easy-to-kill higher mobs?

Much thanks for the guide, I followed it and also started at the mines soon as I could overkill raflowers (20ish iirc), around 50 hours invested 
Though why did this one end up having to transfer to novaha 'cus of overlevel when others here got it before even lvl 40?
Note: I did also kill all bats and small orcas passed through in the mines, then just raflowers in novaha (in the pic you’ll see that almost all my kills are overkill counts too).
Didn’t do whale event, no exp tomes or cards used.
