This champion ignores restrictions and penalties imposed by Water.
This ability is most commonly spread in Forglar Swamp, where nearly every champion has it. It allows you to walk through impeding water, as monsoon creates it, without being slowed. Also it makes you immune to a lot of effects, mostly Forglar Swamp ones too, such as flood, drown or bog trap. However it also makes you more vulnerable to the spell boil. Some water creatures from other factions also have amphibious, and some FS creatures don't, such as the G'hern Traitor.
