Gecko Skinning

Gecko Skinning is a Fallout 2 Perk.

This is a special Perk, so it cannot be taken at new levels like other Perks. It can be learned only from Smiley the trapper after you rescue him from Toxic Caves.

You know how to properly skin geckos (except for fire geckos). You can then earn a bit from selling their skins.
 * Notes: Lionheart Perk "Trapper" is very similar to Gecko Skinning. The Fallout 2 Restoration Mod lets you skin Fire Geckos.
