Figured I'd just share a little insight on Artemis. She can one shot at zero uncap. The only determinant of that is how many magical damage attempts you can squeeze out of her. This applies to pretty much every kind of setup except what the top two players are currently running. Magic damage at +0 is worth 160K damage per crit tap skill and roughly 260K at maximum uncap. Hence, run as much speed as possible to help Artemis tap as much as possible. Her normal tap damage is completely irrelevant until you have enough uncaps to be able to one shot in 2 fevers, so you can sacrifice pretty much everything except the crit rate booster (melpo/pantheon) for speed. I run my setup like this to get 2 fevers in under 2 minutes.
Now if you do have top-tier ignition core on Artemis along with max ignite on Semele and Artemis... then the strategy is different and you will be going for maximum per-tap damage. For the rest of us tho, this is probably the most viable path to personal-best times.
Ragna Break 11 Kamikaze Time Trial
Figured I'd post some suggestions for those brave ones wanting to challenge lower boss clear times.
For the ones that have enough gear, this setup is designed to KO the boss in 2 fevers. To be clear, the minimum damage level required here is 48K damage per crit tap and 28K damage per fever tap from Davi. If you meet this requirement, then this team can KO in 2 fevers. The key strategy is to always tap Bathory until just before fever where you slide to stick her DEF down debuff. The rest is up to Bathory's debuff chance, which ends up to be around 10% of your runs. The other 90% will fail miserably, but it's part of the fun.
If you do not have enough gear, then the next best thing is to swap out Bathory for Chang'e and go for a maximum speed 3 fever KO. This is actually a lot more reliable and with a max uncap setup you should be able to get consistently under 4 minute KO with enough practice. In this setup, essentially everybody slides except for Davi. Chang'e can alternate between slide and tap to gamble for that odd chance she resets Davi.
For every conceivable setup, you will want Failnaught and Davi to be the top two attackers to ensure you can wring maximum damage out of them.
This ragna seems kind of dead so... let's get the party going...
