White Mage (Bravely Default) vs Nicholai Conrad (SH2) - Jesus christ, super's right. White Mage also risks not having enough shots of Holy to even -ever- finish off Nicholai. I don't think that's working out very fabulously.
White Mage vs Garr (BoF3) - Garr's pressure -is- pretty bad.
White Mage vs Cid Highwind (FF7) - I'm rather certain Cid 2HKOs fairly leisurely at base (I think WM would need two Protects to avoid a 2HKO sans Angelic Aid shenanigans), which is a lot of pressure to endure off her resources. This doesn't work out.
White Mage vs Chemist (FFT) - Auto-Potion completely wrecks White Mage and even if you allow Safety Rings, they don't cover Death Sentence in-game, so Assassin Dagger is go at worst.
White Mage vs Lilianne Valendorf (MK2) - Abate Water turns a match that'd be just somewhat problematic for Lily into an ugly mopping.
White Mage vs Nergal (FE7) - The counters, they BUUUUUUUUUURN. Nergal also can't be realistically killed if White Mage spends too long healing, even holistically allowing a weakness hit there doesn't help her much.
White Mage vs Shady Thousand (WA3) - Shady's pressure is pretty damned bad here. White Mage may have problems there anyway due to resource woes, but I don't think that's quite enough.
White Mage vs Relm Arrowny (FF6) - Gaia Gear/Earth Rod spamming. White Mage frankly sucks against other healers. Alternatively, Cat Hood's Holy resistance also makes this pretty ugly.
White Mage vs Aguro (Lufia 1) - 2HKOs, isn't much slower. WM would have to two-round here and I don't think his mdur is anywhere -near- this bad.
White Mage vs Spar (BoF2) - Again, White Mage sucking against healing. Spar even has a bit of an anti-magic game ensuring she can't even kill him with her whole stack of Holies.
White Mage vs Black Wizard (FF1) - Kneejerk: WM mdef lowers BW status to turn four and that's not even -necessary-, since White Mage two-rounds Black Wizard of the 0.68 mdur. Tank two shots of whatever the hell he can do, Holy-blitz.
White Mage vs White Wizard (FF1) - Nooooooooooooo such luck here. WW has even worse resource issues at base, but she can wall BD White Mage far better. I think BD WM could actually pull if off if she had better resources, Dispel is pretty useful - but she loses a Holy just by casting Dispel ONCE. And vying for physicals is utterly useless, that damage is Spiritmaster-tastic.
4-8. Not really great. She has some ice/water-related and limited resource spoiling, as well as exploiting egregiously bad mdur some due to Brave-blitzing being a thing that exists, but otherwise she's pretty underwhelming due to her resource issues and poor stats. Clearly a Light.
Mara (DQ4) vs Nicholai Conrad (SH2) - Typical Mara win, 2HKOs and isn't -quite- OHKOed back.
Mara vs Garr (BoF3) - Mara starts crying herself to sleep as soon as she needs more than two rounds to win a fight and Garr -immunes- Fire for pretty much no strings attached. This is ugly, especially since Garr 2HKOs Mara off her amazing 58% PC HP -alone-.
Mara vs Cid Highwind (FF7) - Dear god, Cid OHKOs Mara with his physical under my FF7 averages, this is -gross-.
Mara vs Chemist (FFT) - Mara ain't really doubling -ever- and Chemist has far more X-Potions than Mara has shots of Blazemost. She only makes -any- headway if Chemist misses an Auto-Potion proc, and for her to get into KO range, he'd have to miss about four procs in a row. I dunno, I think this doesn't happen in the 23 turns or so she gets to make it stick for good.
Mara vs Lilianne Valendorf (MK2) - Fire immunity turns Mara into a losing Puny. This is horrifying.
Mara vs Nergal (FE7) - Dear god, overkills.
Mara vs Shady Thousand (WA3) - Refer to Lily and Garr for what happens when Mara can't Blazemost.
Mara vs Relm Arrowny (FF6) - Mara might even go first, but she 4HKOs Relm -before- any evasion shenanigans come into play and Relm uh 3HKOs at worst (likely -2HKOs-, what the hell Mara). Mara completely fails against Fire res with that survivability.
Mara vs Aguro (Lufia 1) - Aguro comes close to OHKOing, but no dice. Mara herself doesn't miss the 2HKO.
Mara vs Spar (BoF2) - Fire res and mdef, Mara goes packing.
Mara vs Black Wizard (FF1) - Welp.
Mara vs White Wizard (FF1) - Welp!
3-9. I'm pretty sure she's actually a Light (below half PC HP against physicals, holy -fuck-), but this pool just loved spoiling her ass. Lots of fire res, which makes her curl into fetal position. Doesn't ever win if she can't 2HKO -and- survive a hit.
Virion (FE13) vs Nicholai Conrad (SH2) - Sniper Ruffles deals 47% PC HP a pop. That's a 2HKO on Nicholai alright. He even 2HKOs back, but goes last.
Virion vs Garr (BoF3) - EDIT: So, Elfboy's right: Garr's -1.22 SD, which isn't bad enough to get doubled by Ruffles. Meanwhile, Garr's 1.66 pdur means Virion clearly 4HKOs. But Garr doesn't -quite- 3HKO back (it's really close, though!), so all the math's moot.
Virion vs Cid Highwind (FF7) - Cid 2HKOs and isn't 2HKOed back, I think.
Virion vs Chemist (FFT) - EDIT: eh sure
Virion vs Lilianne Valendorf (MK2) - I don't think 20% Blocking is enough to handle Ruffles. 40% would if it didn't make Lily go LAST.
Virion vs Nergal (FE7) - One-rounds and isn't OHKOed back.
Virion vs Shady Thousand (WA3) - A whole different tier.
Virion vs Relm Arrowny (FF6) - Outslugs.
Virion vs Aguro (Lufia 1) - Both 3HKO, Ruffles be faster.
Virion vs Spar (BoF2) - Once again, dat 2HKO.
Virion vs Black Wizard (FF1) - EDIT: Operation Burp Elfboy engage.
Virion vs White Wizard (FF1) - Iunno. Ruse2 does pretty much nothing to Virion turn one and even turn two it's pretty sketchy. I think SF's math looks good, but sigh.
10-2. Could be flipped on a couple of these fights (particularly WW and Chemist), but it's still a pretty solid performance. Near-2HKO damage, even off suspect durability, looks good both in Light and in the lower echelons of Middle.
For fun! Let's try out how would Spiritmaster with White Magic allow fare in this field. Since she'd equip for magic damage and accrue roughly the same score as WM on that, she'd be looking at WM pdur more or less, take or leave a couple %, and above average speed, alongside over twice as potent healing for a lot less cost.
DBZ Spiritmaster (Bravely Default) vs Nicholai Conrad (SH2) - Spiritmaster gets 11 shots of Holy and each deals roughly 11% of Nic's health (he resists Holy 25%, IIRC) with one Poison Rod and Black Robe equipped. This makes me kneejerk that Spiritmaster WILL have to heal at least twice, since she needs to land at least nine shots of Holy total. This gets her fresh out of resources. HOWEVER, she gets 20 shots of Aeroga and -that- 10HKOs Nic at worst. Since she's faster, she can actually outlast him this way. Of course, Spirit Ward also puts him in serious trouble - and wow, with spare turns, Spiritmaster actually can boost her damage with Fairy Aid, this is actually pretty cool! Yeah, she has this.
DBZ Spiritmaster vs Garr (BoF3) - Same thing as White Mage.
DBZ Spiritmaster vs Cid Highwind (FF7) - Spiritmaster being above average speed probably lets her pull this off. Maximize HP, heal and now Cid has to face 1.84x raw HP. Chipping becomes leisurely past that, especially with Fairy's Aid in tow.
DBZ Spiritmaster vs Chemist (FFT) - Auto-Potion still brutally ugly against BD low-end slugging.
DBZ Spiritmaster vs Lilianne Valendorf (MK2) - Spirit Ward and holy -crap-.
DBZ Spiritmaster vs Nergal (FE7) - See Lily.
DBZ Spiritmaster vs Shady Thousand (WA3) - Um yeah.
DBZ Spiritmaster vs Relm Arrowny (FF6) - AMAZINGLY, I think the same issue remains here: Spiritmaster can't possibly exploit Relm's horrifying pdur with Gaia Gear setup and her offense sucks against Relm's elemental spoiling and decent mdur. Though I could actually be argued here.
DBZ Spiritmaster vs Aguro (Lufia 1) - Maximize HP => open with healing => leisurely outlasts.
DBZ Spiritmaster vs Spar (BoF2) - uh
DBZ Spiritmaster vs Black Wizard (FF1) - See White Mage, only Black Wizard only gets -one- turn.
DBZ Spiritmaster vs White Wizard (FF1) - EDIT: hm. The resource economy from Save WM MP is actually quite significant here, as is the existence of Fairy's Aid. I think she could go for two Poison Rods here, which would lead to a Fairy's Aided Holy blitz one-rounding... and hell, WW only has -two- shots of Wall. If she attempts that, lol dispel and Spiritmaster goes to town. BD White Mage could attempt a similar offensive twinking, but it doesn't pan out as well because she can't buff her own damage midfight.
9-2. That's a notably better performance! She actually makes Middle this way, Spiritism and White Magic synergize very well.
