Essense of Vulcatrix

Said to be distilled from Vulcatrix's last breath,
this potent potion can empower the strong and destroy the weak.
Once per battle, at the start of your hero
phase, the bearer may drink this. If they do so, roll a dice. On a 1, the bearer suffers
D3 mortal wounds. On a 2+ add 1 to hit and wound rolls for the bearer until your
next hero phase.
