Lost Tradition (5e Feat)
From D&D Wiki
Prerequisites: The ability to cast at least one spell
You are descended from a group of spellcasters who had different ways of mastering magic, and you follow in their tradition. Choose one ability score. You gain the following benefits:
- Your chosen ability score increases by 1, to a maximum of 20.
- Choose one spellcasting class that you have at least one level in. Your spellcasting ability for that class is your chosen ability score, instead of that class' normal spellcasting ability. Your chosen class cannot have its spellcasting ability changed again.
You can select this feat multiple times. Each time you do so, you must choose a different spellcasting class.
