Godlike
Ultimecia (Final Fantasy VIII) vs Kefka Palazzo (Final Fantasy VI) - You misspelled Kefka, CK.
Sephiroth (Final Fantasy VII) vs Elyon (Breath of Fire: Dragon Quarter) - Yeah.
Heavy
Hero (Dragon Quest V: Hand of the Heavenly Bride) vs Chrodechild (Suikoden Tierkreis)
Blue Mage (Final Fantasy V) vs Aschen Brodel (Super Robot Taisen OG Saga: Eternal Frontier)
Middle
Liu (Suikoden Tierkreis) vs Marie (Eternal Poison) - Delirium + Pyro III don't KO, Liu's faster and has healing. Sadness.
Lilianne Valendorf (Mana Khemia 2: Fall of Alchemy) vs Fauxnel (Valkyrie Profile: Covenant of the Plume) - Lily can get Seal immunity on three different armors:
Heaven's Silk: ATK +18 DEF +53 RES +53 SPD +18
# 00-35 - Single Feather: SPD +5.
# 15-60 - Broken Seal: Seal immunity.
# 40-85 - Prompty: -7% action wait time.
Silver Threads: DEF +66 RES +80
# 00-35 - Wall of Light: +15% chance to block magic elemental attacks.
# 15-60 - Broken Seal: Seal immunity.
# 40-85 - Dampener: RES +10.
La Matador: DEF +31 RES +61
# 00-10 - Mana Shield: +20% chance to block magic elemental attacks.
# 00-35 - Broken Seal: Seal immunity.
# 15-60 - Magic Block: +10% chance to block magic elemental attacks.
Heaven's Silk for more speed or La Matador for random magic blocking are probably the best ones for this match.
Hm, with Heaven's Silk she goes first to me, which she needs if she wants to outslug. Glaceration -> charge -> charge -> activate would KO, but... Fauxnel 3HKOs back it looks like, so that won't work. If she goes for any other kind of damage, Reflect Sorcery screws it up. So yeah, depends on status weapons. I'll try and test those later this week then.
EDIT: Kill's rate is about 25%. The other status weapons are about 40%. Slow on the cannon is about 60%. Lily gets three shots of the ID, which is... 58% chance to hit overall. Enough for me, unless there's something I'm missing.
Light
Sanaki (Fire Emblem: Radiant Dawn) vs Cinnamon (Mega Man X: Command Mission) - Hm, Cinnamon goes first and... 2HKOs quite solidly, but Sanaki gets a counter in there. Hm, she 2HKOs with Forged Light if Flare kicks in (even with a higher average), but that's only 47% chance. I guess evasion would tip it if I gave Sanaki leadership bonuses but...I'm not so sure about that anymore. Generally did allow it, but realized it's kind of similar to allowing Alma equip swapping which I didn't allow, so... need to figure out which way I want to go on that, though to be fair I'll go this way for now.
Bernadette Egan (Suikoden V) vs Judith (Tales of Vesperia) - Sure.
