I was gonna edit my post in the last page to fit this one in since this is also a Castlevania reference but I feel like edit spamming is annoying and Molly isn't even playable so
Switchboard Witch is a reference to Lucy Westenra from Grimoire of Souls.
SA Idea: Grimoire Support
-Gain 5/6/7 seconds of Heavy Regen and Immunity for every 10th combo hit inflicted.
-Inflict Hex for 15 seconds if suffering from 4/3/2 debfuffs.
Edit: it has come to my attention that there is a song by a band called The Resonance titled Switchboard Witch. While it's pure coincidence that the names are the same, screw it. It's a reference to that now. I listened to the song and I personally like it.
Something isn't Castlevania-related:
Flaming Shaman is a reference to Tomato Men which are recurring enemies throughout the Mana franchise.
SA Idea: Flaming Bubbles
-Gain a stack of permanent Armor for every 15/12/10th combo hit suffered except when being hit by a Water element fighter.
-30% chance for projectile hits to inflict 4/5/6 seconds of Bleed and Curse. If blocked, inflict Inverse Polarity and Armor Break instead.
Nurse Darko is... AND DON'T SHAME ME FOR THIS, a reference to Corpse Husband and the usual color palette associated with him. The Countervenoms are colored a dark green (Detox) to reference Sykkuno, a bright red (Paralysis) to reference Valkyrae, and a dark cyan (Sedative) to reference Disguised Toast.
SA Idea: Ruined Life
-Inflict a 20-second Doom effect when dropping below 11/22/33% and if the opponent is suffering from any debuffs.
-If suffering from Bleed, Curse, or Immobilize, inflict Cripple, Armor Break, and 1/2/3 stacks of Bleed all for 5/7/10 seconds.
Killer Killer is a reference to Natalya, an Assassin character from Diablo II.
SA Idea: Art of Assassination
-Using a Special Move has a 30% chance to give 3/4/5 stacks of Precision.
-Dashing opponents are inflicted with Heavy Bleed for 5/7.5/10 seconds as long as Painwheel is alive.
