Force Spells (物理魔法, butsuri mahō)? are a branch of spells appearing exclusively in Megami Ibunroku Persona, which serve as part of the offensive spell list, alongside Elemental Spells, Light Spells, and Dark Spells. Spell types that fall under Force spells are Electricity, Nuclear, Gravity and Blast, representing the four fundamental interactions of nature: electromagnetism, gravity, and the strong and weak nuclear interactions. Primarily, personas and demons who are weak to most elemental spells will use force spells and vice versa.
