The Warden was inspired by a book series.
Wardens are full casters designed to be combat wizards, able to thrive both in the utility capacity and on the battlefield without needing to worry as much as a caster with fewer hit points or armour options. They also specialize in countering and shrugging off hostile magic. The can bolster their spells with Battle Magic and at higher levels they can master a school of magic to make their spells even more potent.
You have three subclasses avaible as a Warden: Blaster, Defender, and Striker.
The Blaster is a long range damage focused subclass that has the capability at high level to wipe out a village from the next horizon.
The Defender is a close combat support subclass the gain heavy armour and shields and can use a shield as a spell casting focus. At higher levels they gain defensive buffs that help them become very difficult to kill
The Striker is a close combat damage dealer wading in with blade and spell alike. They gain martial weapons and can use their Battle Magic to futher power their blows. At higher levels they can weave their spells and melee stikes together for devestating results.
