tyler, you just talked about "karma" on another thread of yours and still love trolling like this?
heh, wait for the next karma turning into another bitch for ya!
ozjosh22,
i dont think we have any deserts in this game.
aurochs spawning tiles are, like others said above, grassland, heath, and moore. (read above again)
(and if you are looking for sand, then you will need to go to beaches and no aurochs spawn there.)
you can tame them anywhere you want as long as you have them close to you, but you will most likely be taming them where they spawn.
if you are not familiar with taming,
search "taming" and/or "guide" on the forums and you can find a few good guides to follow. (or wiki when it is back up.)
and you may want to ask your simple questions on
this thread for better replies.
and finally, id suggest you to try checking stickied threads before asking anything next time.
