Stammelford's philtre

The formula for this potion must be acquired before it can be brewed.
== Journal entry ==
:Created by Herbert Stammelford, a famous member of the first Conclave, this brew is readily used by witchers who rely on magic, since it augments the intensity of Signs – the damage done by the Igni, the impact of the Aard, the defenses of the Quen, and so on.
:Unfortunately, the potion taps the witcher's Vitality for its power, thus reducing it. Witchers compensate for this loss by consuming the Swallow potion.
:The potion moderately increases Toxicity when imbibed.
:It is recommended for witchers who rely more heavily on magic than on traditional weapons, and before any fight against monsters vulnerable to the special attacks issuing from Signs.
