Ok, so here's a basic plan.
[X] Help Angel WEAPON. That Virus is too dangerous to let go! It needs to be destroyed before any lives are lost.
[X] Plan Stall like Crazy
-[X] Let Angel WEAPON take on Goddess White. She's the closest in power to White.
-[X] Take on the Maiden of the West yourself. Focus on intercepting her attacks with your own, and tanking the ones you can't intercept.
-[X] Have Samael empower Team GEAR and Angel WEAPON, then have him focus on keeping the Maiden of the East from attacking as best he can. James should focus on keeping East's attention focused on himself.
-[X] Have Truth and Gabriel remain close enough that all of the team is within the range of their healing abilities. In the meantime, they should focus on hit-and-run tactics focused on keeping West and East respectively off guard, and hopefully keeping them form using spells. They should immediately retreat whenever they are injured, and wait until they are healed back to near top condition to resume the hit-and-run tactics.
-[X] Before the fight begins, ask if anyone knows who released the virus, and why they did such a thing. If anyone answers, have Michael continue the conversation.
-[X] Purchase Interceptor Fire (50 XP)
Ok, let's explain this. Angel WEAPON is the only capable of stalling White without getting insta-gibbed, so let's have her handle that.
West's base damage is pitiful, only a measly 500. Unfortunately, she gets 5 attacks per turn, so she'll be able to attack us twice without us intercepting her. Assuming that Intercepting her attacks allows us to apply our weapon's Judgement effect to West's attack, her Magic Modifer will be negated. This means all of her incoming damage will be 500 per attack. Now, Intercepting that attack will reduce the incoming damage to 243 by our own damage. That will in turn be reduced by our base resilience to 13, which will in turn be completely negated by our Armored Core Ranking. So, we won't take any damage from Intercepted attacks.
As for the attacks we can't Intercept, assuming West rolls a 1 for her Magic Modifer, our resilience will reduce the damage to 271, which in turn will be completely negated by Armored Core. For quick reference, incoming damage needs to be at least 337 in order to actually deal damage to us, which will still be reduced by 75%. At full power, West's damage becomes 1500, which is reduced to 1270 by our resilience, which is reduced to 318 by Armored Core, which in turn is reduced to 159 by No Longer Human. So, according to my calculations, West will do somewhere between 0 and 159 damage for each of her non-intercepted attacks, 200 which will be healed by Gabriel's Presence of Light. Core Purge can currently deal 1650 damage, so it's practically useless here, so we shouldn't use it. For Truth, her resilience is 125, so she will take a minimum of 375 damage and a maximum of 1375 damage for every hit she takes from West. As Truth only has 2500, it would be best if she avoided being hit more than once, as two hits in a row without Truth disengaging and healing could kill Truth.
East on the other hand has a terrifying attack of 10000, which can decimate nearly all of us. Gabriel is the only one who can tank that without dying, but James' Merely Human trait let's him auto-dodge any attack that deals more than 100 damage, and get a free counterattack. The damage to his body caused by the stress should be healed by Gabriel's Presence of Light. Gabriel's Judgement spell increases her base attack to 8500 + d400 + d500, but she doesn't have the Intercept ability. East might, so if she does, Gabriel powers up, attacks East, and is intercepted by East, Gabriel will be dealt a maximum of 1498 damage, and a minimum of 600 damage. I'd like to take a moment to thank the QM for not giving East a Magic Modifier. So, Gabriel can tank a hit from East and an Intercept, but she should avoid getting hit in the first place.
Due to my preceding analysises (analyses?), I believe that Truth and Gabriel should focus on hit-and-run tactics, focusing mainly on helping keep Solid Core and James alive.
The Interceptor Fire purchase is because our Base Damage is reduced by 500 thanks to Goddess White's presence, do giving ourselves a way to use Interception at range seems like a good idea.
Ultimately, this plan is not about winning. No, it's about stalling long enough for the other WEAPONs to get here, and it is focused around this goal. If we kill any of them, it will only be due to freak chance.
Any questions or complaints?
