A Raider beast should be amazing,like a pet it folllows the raiders and Attack,but you can buy diferent beast(they also drop in raids)and you can upgrade the abilities of the beast,every beast got 3 abilities(the abilities are different on each beast)that they use to help the team.The beast can't die(or can the idea can change)he keeps fighting until there's no raider in the area.Sorry for my english.
