Gelmir Hero's Grave is just...trash.
All the other bullshit aside, Stonesword key item that is located near the wall is just basically a death trap, right? There's no way to leave, you can't even teleport out, your only way is to fucking die over and over to move your runes closer to the passage so you can pick them up safely, you can't outrun the chariot, you can't jump on the chariot, you can't do shit. If anyone knows how to pick up Stonesword key WITHOUT dying I'd be VERY interested to hear the solution.
