Archmage Bloodline

Archmage Specialties
Starting at 1st level, the lineage of master spellcasters courses through your veins and into your spells. Choose two cantrips that deal damage to designate as Archmage spells. You deal an additional die of damage with those spells. When you gain access to sorcery points, you can additionally choose a spell for each spell level available to you (up to 5th) as an Archmage spell. You may treat the spell as if you're casting it with a spell slot that's one level higher if you expend a sorcery point as part of casting the spell. You may change what spells are Archmage spells when you gain a level.

Extended Library
Also at 1st level, your understanding of magic surpasses those of other bloodlines. You learn an additional 1st level spell, which may come from the sorcerer or wizard spell list. You gain additional spells when you gain access to higher level spell slots at 3rd, 5th, 7th, and 9th level, which must also be the same level as your newly acquired spell slots and may come from the sorcerer or wizard spell list.

Arcane Analysis
At 6th level, you can grasp the fundamentals of magic incredibly quickly. When a creature casts a spell or uses a magical effect, you can use a reaction to analyze it. You immediately know the spell if it is one, what type of damage it deals, what saving throw it targets (if any), and how many remaining uses they have of it or how many spell slots of the same level they have remaining. If you are targeted by this spell or effect within the same day of analyzing it, you may use a reaction to apply what you learned, either forcing the attack to be made at disadvantage or gaining advantage on the saving throw, if it has one. You can do this a number of times equal to your proficiency bonus each long rest.

Radiant Knowledge
At 14th level, you can channel the arcane power that you possess into a potent form. As a bonus action, you can assume this form for 1 minute, radiating with energy. For this minute, your spell DC and attack rolls for your spells are increased by 2. Additionally, you may change any damage a spell does to another damage type.

Once you use this ability, you cannot do so again until you finish a long rest.

Grandmaster of the Weave
At 18th level, your mastery of arcanology supersedes all others. When a creature casts a spell that targets you, you may cast *counterspell* as part of your reaction when you use Arcane Analysis. You may spend up to 3 sorcery points to increase *counterspell's* level by 2 for each point expended, up to a maximum of 9th level. Additionally, all of your Archmage spells are treated as if they are cast one higher level than the spell slot expended, and you may expend a sorcery point to increase its level further, for a total of two.
