Roll your relationship dice that you have with a sorcerous heroic icon.
For each 6 you roll, you gain one 7th level or lower spell from any spellcasting class that you can cast this battle. For each 5 you roll, you gain one 5th level or lower spell from any spellcasting class that you can cast this battle.
If the escalation die is 5+, you can swap the escalation die for one or your rolls. If you get no successes, you regain the spell after this battle.
You can acquire one of the new spells the same round you cast this spell. Then select and acquire any other gained spells at the start of your next turn.
You can use your Charisma as the ability score that provides the acquired spells' attack bonuses and damage bonuses (if any). Other ability score references remain unchanged.
As you might expect, each 5 you roll also invokes an icon-related complication or obligation in the tradition of rolling 5s on relationship checks.
