Snecko Skull

Snecko Skull

CommonSilent
Whenever you apply Poison, apply an additional 1 Poison.

Whenever you are the one applying Poison, the amount goes up by 1 before it lands. It checks the giver, not the card, so Poison from powers such as Noxious Fumes and from relics such as Twisted Funnel is raised too, and a card that applies Poison several times gets the bonus on each application. Poison that enemies put on you is untouched.
