School of Channeling

A subclass focused on using "Channel Spell" to your advantage. Channelers usually stay behind the rest of the party, building up their channeled spells before casting them all at once. Very much a glass cannon. (Look up the Channel Spell cantrip for more context)

Level 3: Channeling Savant

Starting at level 3, you learn the cantrip "Channel Spell". This does not affect the amount of known cantrips you have. You may cast "Channel Spell" as a bonus action. You may cast a channeled spell as an action. Channeled spells you cast have an additional 1d4 on their spell attack roll.

Level 3: Arcane Sacrifice

Starting at level 3, you may sacrifice a channeled spell with a bonus action. The next time you cast a combat spell, you may add 1d6 force damage to that spell's damage for each level the sacrificed channeled spell had (1d6 if it was a cantrip or a first level spell)

Level 6: Explosion of Arcana

Beginning at level 6, for one spell slot of the same level as your highest-level spell that you have channeled, as an action, you can cast any number of spells you've channeled. You cast these spells in a sequence determined by the level of each spell (you pick which spell goes first if 2 or more spells are the same level). You decide the targets/area of effect of any spell you cast as you cast it. Any reaction spell fizzles if cast this way. You may only do this once every long rest.

Level 10: Quick Burst

Beginning at level 10, you may cast non-reaction channeled spells in place of your opportunity attack or as a reaction. You may also cast "Channel Spell" as a reaction or in place of your opportunity attack.

Level 14: Master of Channeling

Starting at level 14, you may cast "Channel Spell" twice with one action as long as both channeled spells are the same level and same spell school. You can also use Explosion of Arcana after a short rest or a long rest now. You may add 2d4 instead of 1 on the spell attack rolls of channeled spells.
