Quickest Sparks in RoEFollow

I'm a returning player looking to jump right into RoE. Anyone have any advice on the quickest way to do this? I have multiple 99's with good gear.

Thanks!

Quickest way, at least in my opinion, is really just to grind out the repeatable ones that ask you to do X amount of damage per hit, Y amount of times. If you get one of the stronger melee DD, such a War or Drk or something, where their melee hits alone are likely to be high enough to inflict that damage, you can breeze through that quickly, and then just continue with it. Likewise, do ones that could potentially overlap with that one, since I know there are a couple non-repeatables that require similar actions to complete.

Another alternative is to pick a job you don't yet have levelled and spend a week or so getting it around lvl 70-75 with trust NPCs.
(Maybe even less then that if you have more play time.)
By then you would have capped sparks and can buy pretty much anything.
Checking what mobs your fighting (which will always be EP) and what crystals they drop is good for opening crystal specific tasks while repeating regional based tasks at the same time is good too.
It's not the ultimate-super-duper way but if your a person that likes to complete lots of different tasks at the same time rather then just grinding sparks then this is for you.

Saying that, if you really don't want to level another job then rdmcandie has already came up with a good one:
Dual wield 2 different Eminence weapons and in Abyssea, you can equip RR atma that enables you to crit hit fairly often so if you can hit for over 500+ on each hand, it doesn't take very long to gain sparks that way.
I think if you can also use an AoE ws around multiple worms, that may count towards 500+ but I am unsure.

(But you need to have sparks already to be able to buy these weapons.)

Monstrosity in Bubu with your level capped. Set zone kills, earth crystals, fire crystals, monstrosity kills, general kills, and then whatever else you think you could accomplish. But basically just get to 30 and munch through EPs on the east side of the zone.

Ah yes I thought so.
Then the correct atmas would be at least VV for regain, RR for crit hit rate and maybe apoc incase you die.
I was using circle blade recently and that seems to work too.

You can also swap out the Critical-related Atmas for multi-attack and attack speed Atmas, head to Abyssea - Tahrongi, and kill Bog Bodies (Qutrub). They take double damage like other Qutrub mobs.

This.

Thank you for this advice. I have never fought Qutrubs and didn't know this. Knocked out the last few sparks to +1 my body last night and this made light work of it.

Yeah, it wasn't my first thought, either, as evidenced by my own post. If competition isn't an issue, I suspect it'd also trounce other options quite handily. Wondering if anyone's particularly done it and could give a rough estimate on individual completions. Running crudely off 240 delay and then 40% Haste, I get 10 minutes to land 250 hits at perfect ACC, but this obviously won't fly due to movement between mobs. I'd also be generally concerned they wouldn't respawn fast enough if you are landing 500+ a whack consecutively.

So, basically 2.5 hours for 109 AF if starting from scratch. Can probably feel grindy after a while. x.x

The SKCs are great. If you've got a solid group, doing the Difficult could also make the runs pretty profitable.
