How work the ceckpoint in grim dawn? In titan quest there was the rebirt fountain but here i dont se nothing like that. Where i do it wrong?
Rebirth fountains were dropped very early in development. When you exit the game you’ll either restart in Devil’s Crossing, Homestead or Fort Ikon depending on where you are in the game. You’ll then need to rift back to the nearest point to where you ended the previous session and then walk/run to it. You can blame Diablo for that, worked the same way in that game. 
So evrey timo you start play again you have to teleport to the last rift. At last in tq when you stop at the fountain when you restart you are where you left. Here it is similar but not the same and you are forced to exit only when you reach the the next discovered rift or you l’ be forcede to kill the same enemies time and time again
yep, spot on. Usually you can reach the next rift in maybe 5-10 minutes, if you decide to not clear the entire area but go straight for it / follow the road
