Transmutation
Transmutation Wizards are students of spells that modify energy and matter. To them, the world is not a fixed thing, but eminently mutable, and they delight in being an agent of change. They wield the raw stuff of creation and learn to alter both physical forms and mental qualities. Their magic gives them the tools to become a smith on reality's forge.
Subclass Features
Transmutation Savant
Choose two spells from the School of Transmutation, they must be no higher than a spell you can learn normally (2nd level at level 3) and add them to your spellbook for free.
Whenever you gain access to a new level of spell casting you can add one spell of that level and of your School to your spellbook for free.
Fluid Self
The easiest material to manipulate is your own body. The spell Alter Self is added to your spellbook, if it is not there already. You can cast it times per long rest equal to your INT modifier (Minimum 1) without expending a spell slot.
Crafter
You can create whatever you could ever hope to need in a flash. You can add the spell Fabricate to your spellbook, if it is not already there. You can cast the spell during the course of a long or short rest without expending a spell slot.
Elegant Swap
When a creature deals damage within 30 ft of you, you can use your reaction to change the damage dealt, the damage cannot be changed from non magical to magical and vice versa. You can change any damage type to Acid, Cold, Fire, Lightning or Poison damage.
Shapechanger
You gain mastery over your form. You add the Polymorph spell to your spellbook, if it is not there already. You can cast Polymorph without expending a spell slot. When you do so, you can target only yourself and transform into a Beast whose challenge rating is 1 or lower.
Once you cast Polymorph in this way, you can't do so again until you finish a short or long rest, though you can still cast it normally using an available spell slot.
Masterful Swap
You can modify damage in more mysterious ways to better suit your needs. When you use elegant swap, you can change the damage to Necrotic, Psychic, Radiant, or Thunder damage.
Immortal Soul
While the body may be slain and rot, your soul and mind are too valuable to lose. You have prepared a secret, ethereal transmutation circle on your soul. If you die the transmutation circle flares to life and casts the spell Reincarnate on yourself without expending a spell slot or requiring materials. The spell cannot fail unless direct divine intervention interferes. You get to choose your new body or you may opt to roll as described in the spell.
You can recreate the transmutation circle once used every 1D6 +1 years.
