Arcane Field: You create a field of arcane power granting increased attack speed to any ally standing in it. Size: about 2-3 meters so that multiple people can squeeze in. Additional effects gained either through spell perks or innately could be that whatever ally spell lands on the circle, it will spread its effect on it, meaning you can throw a fireball in it will have a wider splash radius, or throw a single-target heal and have it heal multiple people - of course it doesn't have to spread its full effect, 50% for example.

Another effect could be to slow enemy movement/attack speed by a percentage. Imo it would be a fun support spell.

more non combat spells that just add a magic feel to the game like telekinesis or changing the colour of your hair, stupid stufff like that.

You mean you'd like to see more non combat spells or what? I'd like that too but it might be hard with limited action bars, we'd have to make sure never to go into combat with them slotted.
