Arcane Knight (Melee DpS/Support): Group buff spells (Haste, change the physical damage of the group's weapons for Fire, Arcane or Frost damage), remove magical debuffs, resistance to magical damage in a group, and some short-range spells Arcane damage.
See you
The Idea with the Arcane Knight is sooo good!!
I think that for the specialization of the mage you have to take inspiration from the best wizards: (harry potter, lord of the ring), it can be a good idea I'm sure you'll find a good idea you have a team that has a lot of talent I saw the evolution of the game it's very much looking forward to seeing the rest good luck for the ideas and the work.
