More lost spells from sources around the web which are updated for 5e Ars Magica. This spell destroys pawns of vis. I have to ask why a caster would do this (demonically tainted vis perhaps?), however it seems a legitimate use for Perdo Vim.
Perdo Vim General, R: Voice, D: Momentary, T: Individual
Up to 1 pawn of Vis per 5 levels of this spell are destroyed.
(Base General, +2 Voice)
