At 9th sorcerer level, you can perform a soul burn, sacrificing 1d6 HP but gaining one of the following effects as a free action:

• Cast a lvl 1 spell you know at 1st level, without expending a spell slot. The spells effect cannot heal you or allies.

• When attacked, make a block check without expending block.

• Gain a 1d6 bonus to a save or block check.

• Gain a +1d6 damage bonus to a spell or attack you are performing.

• Gain a +1d6 bonus to an athletics, acrobatics, intimidation, or performance check.

At 9th sorcerer level you gain the following:

• Soul Dice - You gain a number of soul dice equal to your charisma bonus.

• Spirit Dice - You gain a number of spirit dice equal to your wisdom bonus. 

• Magic Dice - You gain a number of magic dice equal to your intelligence bonus. 

All dice are restored upon making a long rest. During a short rest, only one group of dice is restored. All such dice can be used in place of losing HP when using soul burn.
