Sorcerer: Titian Heart origin

Divine will produced the massive titans, ancestors of the the giants. As the children and creations of deities, titans are filled with magic so powerful that they require enormous forms to contain it. When a titan’s magic mixes with that of a sorcerer, there is a chance for the smaller being to gain the ability to channel the titan’s magic by altering their form. A burst of flame or surge of wind from a Titan Heart sorcerer commands fear and respect.   Ancient Knowledge. Starting at 1st level, you are proficient with martial weapons and can speak, read, and write Primordial. Knowing this language allows you to understand and be understood by those who speak its dialects: Aquan, Auran, Ignan, and Terran.   Titan Manifestation. Also at 1rst Level You can physically embody your connection to titans for a short time as your form takes on aspects of the original Titans. As an action, you assume the form for up to 1 minute. It ends early if you are knocked unconscious or if you choose to end it early as a bonus action. While in this form, you gain the following benefits:

• Your size increases to Large.
• Your AC increases by 2.
• When you make a melee weapon attack, you can use Charisma, instead of Strength or Dexterity, for the attack and damage rolls.
• Your weapons and equipment grow to match your new size. While these weapons are enlarged, your attacks with them deal 1d4 extra damage.
• Your spells and melee weapon attacks deal double damage to objects and structures.
• You also know and can cast the blaze, cataclysm, daybreak, glacier, and quake spells as sorcerer spells. These are special primordial spells described at the bottom. You can use this feature twice. You regain both uses when you finish a long rest.

  Strength Of Magic. Starting at 6th level, you can use your Charisma modifier instead of your Strength modifier for Strength checks and saving throws, as your magical connection to the titans grows stronger.   Toughened Grace. Also starting at 6th level, while transformed by your Titan Manifestation feature, your total bonus to AC from that feature increases to +4 and you can attack twice, instead of once, whenever you take the Attack action on your turn. Additionally, you can use your Titan Manifestation feature three times, regaining all uses when you finish a long rest.   Titan’s Will. Starting at 14th level, you can choose to grow to either Large or Huge size when you use your Titan Manifestation feature. If you become Huge, the bonus damage for your weapon attacks increases from 1d4 to 1d10, and your walking speed increases by 20 feet. While you are Huge, you can expend a spell slot and stomp the ground as an action, releasing a wave of destructive energy. Each creature within 20 feet of you must make a Constitution saving throw against your spell save DC, taking 2d6 thunder damage per level of the spell slot you expended and getting pushed 10 feet away from you on a failed save, or taking half the damage and not getting pushed on a successful one. Additionally, you regain 2 sorcery points when you use your Titan Manifestation feature. While your Titan Man infestation feature is active, you can spend 1 sorcery point to treat a spell you cast as if you used a spell slot one level higher than the one you spent to cast it (to a maximum of 9th level).   Ancient Colossus. Starting at 18th level, you have advantage on Strength checks and saving throws while your Titan Manifestation feature is active. In addition, when you cast a primordial spell available to you through your Titan Manifestation feature, the spell is cast at a minimum of 3rd level, even if you only used a 1st- or 2nd-level spell slot to cast it. If you spend a sorcery point to increase the level of a primordial spell that was cast using a spell slot of 1st or 2nd level, treat the spell’s effects as if you had used a 4th-level slot. You can also unleash the full strength of the magic you draw from the Titans. When you cast a spell that deals damage to one or more targets while your Titan Manifestation feature is active, you can choose to deal maximum damage instead of rolling dice. You must declare that you are using this benefit before you cast the spell. Your Titan Manifestation feature ends immediately after the spell is resolved.
