Atlantis is an underwater sea race

Tidal Wave: once per battle, the hero can use the "Tidal Wave" ability, which grants creatures the confidence that they are in a naval battle for three turns, and they will gain all the bonuses of their element. Only for 3 turns.

Confidence: the hero can cast the "Confidence" spell on creatures of his faction (description above, see the mermaid's abilities) an unlimited number of times in battle.
