Darkstone After getting the first four crystals, the obelisk appears in the town. The skies become dark and rain starts. This is the normal condition for exploring the last two lands. If you want to clear the lands of creatures in daylight (no eyestrain), do not get the fourth crystal -- leave it in the dungeon. You can load up on potions and completely clear out and map the lands of Marghor and Serkesh with good weather. Then return for the fourth crystal. There will be no above-ground ambushes from the dark as you continue the game. - o -
