Sympathist

A sympathist is an existence similar to an alchemist, who's methods of magic involve converting multiple forms of energies through force of will to create a particularly powerful effect. 

Tool Proficiency

3rd-level Sympathist feature

You gain proficiency with tinker's tools. If you already have this proficiency, you gain proficiency with one other type of artisan’s tools of your choice.

Sympathist Spells

3rd-level Sympathist feature

You always have certain spells prepared after you reach particular levels in this class, as shown in the Sympathist Spells table. These spells count as artificer spells for you, but they don’t count against the number of artificer spells you prepare.

 

Sympathist Spells

Artificer Level	Spell
3rd	mage armor, shield
5th	hold person, warding bond
9th	counterspell, slow
13th	dimension door, phantasmal killer
17th	hold monster, telekinesis

Heart of Stone

3rd-level Sympathist feature

Your mental strength has a strong foundation.  Beginning at 3rd level, you have advantage in Constitution Checks made to maintain concentration.  In addition, when you fail a Constitution saving throw to maintain concentration on a spell, you can instead use your reaction to choose to succeed. You can do so a number of times equal to your Intelligence modifier (minimum of once), and you regain all expended uses when you finish a long rest.

In addition, due to your studious efforts, you have expanded your skill sets.  Choose two of your skill proficiencies, or one of your skill proficiencies and your proficiency with one of your artisan's tool sets. Your proficiency bonus is doubled for any ability check you make that uses either of the chosen proficiencies.

Unshakable Alar

5th-level Sympathist feature

Your will is Ramston Steel.  While you are concentrating on a spell, when you or a friendly creature within 30 feet of you must make a saving throw, the creature gains a bonus to the saving throw equal to your Intelligence modifier (with a minimum bonus of +1).

Heat From Blood

9th-level Sympathist feature

Beginning at 9th level, you can cast a spell using the warmth of your own body to empower the spell to deal double damage.  You can use this feature a number of times equal to your proficiency bonus(PB).  After each use, you must succeed on a Constitution saving throw or suffer Binder's Chills, 1d6 cold damage.  On your last available use of this feature, you must succeed on the Constitution saving throw without the benefit of the Heart of Stone feature.  If you fail, you also suffer one level of exhaustion.

Double Binding

15th-level Sympathist feature

Starting at 15th level, you have learned to break your mind into two.  As such, you can concentrate on two spells at once.  If you lose concentration from damage or becoming incapacitated, you will lose concentration on both spells.  If you are concentrating on two spells and you attempt to cast a third spell, you must choose which of the two previous spells you will stop concentrating on.  The spells cast in this manner cannot have a damaging component.
