Oooosu,
Welcome to my newest attempt to make the life of the spirals more enjoyable during their time on cradle.
Introducing: Bosses DeSciphered.
A challenge which involves brutally murdering bossed then go to their house to clog up their toilets and raid their fridges afterwards.
Take at least 2 alchemers, then proceed in beating the 4 main bosses in less than 15 minutes. Make a vid and upload it to twitch preferably, but youtube is also acceptable . The fastest team will get a rocket propelled snipe issued by Boswick himself.
If you're really looking for a challenge, don't take umbra on JK and Snarb, and no elemental on RT.
This challenge will end the day OOO decides to AA charge us with the gunner update.
Just saying that <15 Minutes isn't possible with Alchemers alone. Maybe 3 Bosses? Yes. Vanaduke has resistance to Elemental and Immunity to Shadow:
That's 38 Damage per shot and 70 Damage per charge without buffs. Just from a Nova Driver.
Blitz Needle does 4080 Damage for the charge against effective, and 675 Damage for non-effective.
Now how many charges does it take on Average to cause Vanaduke to switch phases? About 4 Charges. This means that each non-mask phase is about 13600HP.
Mask-Phase is about 5 charges which is about 3375HP.
(I'm guessing since it's been awhile since I've ran Vanaduke without Damage Bonuses on my Blitz)
This rounds to 47550HP.
Alchemer Switching does 38 damage per second. So let's do some math here:
38x900 = 34200HP.
That means that even if you had every bullet ricochet off of Vanaduke, you wouldn't be able to beat him within your desired time.
Your contest is a lie, get out.
