Petri's Philter is a potion that raises Sign intensity. This base tier gives +15% Sign intensity, holds 3 charges, lasts 30 seconds per dose and adds 25 Toxicity.
Sign intensity sets how effective Signs are. More intensity raises Igni's damage, Quen's shield, Yrden's slow and Aard's knock-down chance, and makes Axii last longer. That makes Petri's Philter a potion for a Signs build.
