In Death's Gambit, players will have to fight different types of enemies, each with their own abilities and traits. One of these opponents is the Ghosts, which differ from others in that physical or magical attacks do not work against them. They are immune to any weapon or skill, no matter how strong they are. But these supernatural beings are extremely weak against sunlight.
So whenever you come across a ghost, throw a sunstone at it. This will show their true physical form, which can be attacked with any weapon or magic skill.
Another good news about Sunstones is that they are fairly easy to obtain as they are not a rare item. You can acquire such stones by killing crystal enemies, or go for them to the merchant Jaco Basilus. He is in a red tent located in the game's hub area and sells sun stones for 20 hopes.
