 Sea Reapers are amphibious , humanoid swimmers . Therefore , they regain health in contact with water , and the game 's Piranhas do not attack them . To travel fast over land , players can " turbo boost " their Reapers to targeted areas . The Reapers can use swords , bows , and spells , such as summoning firestorms or tornadoes , in combat . Planet Moon Studios initially conceived the Sea Reaper single @-@ player character , Delphi , as evil , but later gave her a conscience .
