All Magical Damage Skills do not affect Boss Monsters unfortunately, bringing spellcasters out of their list as they completely ignore magic from players. The magic attack spells listed are:
Fire Bolt, Ice Bolt, Thunder Bolt, Thunder Storm, Fire Wall, Fire Pillar, Meteor Storm, Jupiter's Thunder, Storm Gust, Misty Frost, Lord Of Vermillion, Water Ball, Chain Lightning, Hellfire, Comet, Soul Strike, Napalm Strike, Heaven's Drive, Freezing Mist, Jack Frost, Life Drain, Tetra Vortex, Soul Expansion, Earth Strain, Hell Inferno, Crimson Rock, Fire Ivy...
Mage classes must stay and run away from those pesky boss monsters with magic immunity.
Support Skills do not affect Boss Monsters, with exceptions as they use Monster Skills on themselves.
Monster Scan, Magic Rod, Blessing, AGL UP, Gloria, Magnificat, Endow Elements, Aspersio...
All will not work on boss monsters/bosses, this can make all spellcasters totally useless; they bring them out of their list literally yet unfortunately.
