01) Aegis of the Dragon Armor+
02) Flamehunter's Garb+
03) Sky Guardian+
04) Wicked Wrath+
05) Storm Sorcerer+
06) Kaleidoscopic Starmetal Rainment+
07) Half-Dragon Warrior's Armor+/Armor of the Infernal Lord+
08) Admiral's Battleworn Regalia+/Dark Prince's Royal Armor+
09) Deep Dragon Mail+/Swamp Shaman Robes+
10) Horrible Wurm Costume+
If I've remembered correctly, for both main knights, Regalia+ can give Starmetal+ 303 damage, twice for 606, need 1 more hp to 2 shots, thus Armors which above ATK 1209 can 2 shots Starmetal+, otherwise need 3.
Starmetal+ should be able 3 shots any armors, confirm?
Feel free to discuss.
