this school would be similar to life and fire because it would be a healing school like life and it's attacks would be damage over time spells but it is primarily a healer so its damage output would be about the same as life but its healing power would be on par with life and it's stats would match life's stats
one of the attacks could look like this a cloud appears above the dueling circle with white pearly gates the gates slowly open and an arch angel in golden armor appears and comes out of the gate pulls out his divine sword holds it up right and a yellow light starts to emanate from the sword and a huge holy bubble covers your enemy then explodes with him/her inside dealing a small amount of burst damage then dealing the rest of its damage over 3 turns
as for a heal spell a cloud appears and a yellow light shines down on your wizards healing you for 860
The spells you describe sound a bit like Snow Angel crossed with Judge and a bit of Regenerate. It seems like the other schools have this covered. It does sound cool looking though. Even though they are not a separate school, there are already paladins in the spiral. Wizards who embrace knightly ideals of defending the weak and saving others wander the spiral as paladins. It's informal, not an organized group, just wizards trying to do what is right, even when no one notices. Paladins join fights with last moment heals that turn defeat to victory, shield the injured, help lower level wizards win boss battles, make stands against bullies (by talking to the one bullied and teaching about report, ignore and change realm controls), reporting as needed, and sometimes acting as a WC tour guide for level 2 wizards just learning the game controls. You may already know a paladin. You may even be one. Paladin- it's a state of mind, in action.
