Arcanist

When a promising young Wizard with truly generational access to the Arcane Weave is given the proper nurturing, they can become truly transcendent - with uncapped knowledge of the Arcane and power beyond ones wildest dreams, Arcanists are the result of pure spellcasting might. They work to perfect the art of Spellcraft, and look to change the makeup of the world itself with their magical power.

Level 3: Arcane Savant

3rd Level Arcanist Feature

Choose three spells from the Wizard Spell List (each of which must be no higher than Level 2) and add them to your spellbook for free.

Additionally, when your connection to the Weave grows stronger and your ability to cast higher-order spellcraft increases (specifically at levels 3, 5, 7, 9, 11, 13, 15, and 17) you may add an extra spell from the Wizard Spell List to your spellbook for free. The chosen spells must be of a level for which you have spell slots.

Level 3: Uncovering the Old Ways

3rd Level Arcanist Feature

Your unique access to the Arcane Weave allows you to uncover Magical Secrets in ways that others will never comprehend. You gain expertise in the Arcana Skill, and you may add your Wisdom Modifier to any Arcana D20 Tests.

Level 6: Ersatz Arcanum (6th Level)

6th Level Arcanist Feature

At 6th level, you can effortlessly duplicate spells you see cast whilst in heated battle as your arcana manifests itself as a mirror to the powers thrown by those around you. 

Once per round while in combat, you may use a charge of Ersatz Arcanum to learn and prepare that spell until you complete a long rest. This spell can be from any class, as long as you have the requisite spell slot to be able to cast it. You may do this a number of times per day up to your proficiency bonus.

Arcana Overwhelming

10th Level Arcanist Feature

Your innate understanding of the inner-workings of the weave allows you to place extra power into specific spells. When you cast a spell that requires a creature to make a saving throw to resist its effects, you may force that target to roll with disadvantage. You may use this ability a number of times equal to your proficiency bonus per day. You may recharge this effect with the expenditure of a third level spell slot or higher (no action required). 

Level 14: Ersatz Arcanum (14th Level)

14th Level Arcanist Feature

Your connection to the greatest power in the universe, combined with your innate ability to understand the intricacies of spellcraft, give you an edge against other spellcasters you face throughout your adventures. You gain the ability to replicate the exact motions of a spell’s casting to duplicate its effect.

Upon seeing the casting of a spell 5th level or lower, you may use a reaction to hold the spell in your mind's eye for a brief moment - before unleashing it upon your foes with devastating force. You may immediately cast the copied spell as part of that same reaction, mirroring the effect for your own devices. 

You may use this feature a number of times equal to your proficiency bonus each day.
