C98 Ask for Help

The system notification read, "Your mount, Night Shade, has acquired the skills: Charge, Ram, Skewer, Heavy Strike, Weapon Ward, Pierce, and Intimidate. Due to the transformation into a Dragon-Phoenix Combatant, your Fellbeast will automatically convert to an Arch-Combatant class restriction."

Arch-Combatant class restriction? What's that about? I better check the help system. Ugh
