Magical Researcher Feat

Prerequisite: Proficiency in the Arcana skill

• You delve the secrets of magic. You can make scrolls of spells you don't know, but each crafting check takes 8 hours (this can be completed incrementally). When you craft a scroll or make a magic item that reproduces a spell that deals damage, you can change the damage type of that spell it reproduces. Doing so raises the difficulty of crafting it by +2. Additionally, you can cast a spell from a scroll even if it is not on your spell list. If it is a higher level than you can normally cast, you have advantage on the spell casting check to cast it.
