I had an army of 7 dodos on moble (single player so I had no tribe to back me up). I had the game set to brutal difficulty, and I was still level one (brutal difficulty makes you get almost no XP) I saw a dilo, and thouht we could take him, and I was wrong. It turned out to be level 225 ish and killed all but one of my dodos, and 2 shot me. I managed to recover 4 of the 6 fallen dodos inplant, but those 2 whose impants were lost will be remembered. DO NOT engage on brutal difficulty without a mount. Especially without finding its level first.
