Going down the list of the new Circle Casting options in Heroes of Faerun and boy, is it going to have an effect. The below video explains each in detail. For example, anyone with the spellcasting or pact trait can be a secondary spell caster. That means a level 1 caster dip, magic initiate feat, or other minor thing that gives a spellcasting ability means you can help augment other casters. One of the things you can do is share concentration.
So level 9 wizard casts a concentration spell with a level 8 fighter/1 wizard. The f/w takes on the concentration aspect, allowing the spell to take effect and last while the level 9 wizard casts another one the next turn on their own. And that's just the start of potential game breaking stuff.
Or you can increase an AoE by 20 feet. An example given is increasing the width of a lightning bolt from 5 ft wide to 25 feet wide. Again, that level 1 dip PC can help do this.
