Snakeater/Fallout 2

Snakeater is a perk in Fallout, Fallout 2, Fallout Tactics and Lionheart.

Fallout, Fallout 2 and Fallout Tactics
+25% poison resistance per rank. There's only one in Fallout and two in other games.

The perk is functionally useless, as poison is never a major problem in the games.

Lionheart
+30% poison resistance per rank. This perk cannot be taken if the player has the Venom Ward perk.
