In my experience playing Phasmophobia, testing for the Dayan ghost requires a careful balance between movement and stealth. The unique trait of the Dayan is that it changes its speed based on whether you are moving or standing still—it speeds up when you move and slows down if you stand still. To effectively identify this ghost type, I recommend finding a secure hiding spot where the ghost cannot find you, rather than just demonstrating in open areas like the van. When you're hiding, hold down a movement key to trick the game into registering movement while remaining concealed. This technique helps trigger the ghost’s speed change without exposing yourself to danger. By moving into your hiding spot while holding the movement key, you should observe the ghost’s behavior closely: it will increase its speed if it's a Dayan, allowing you to differentiate it from other ghost types. This method offers safety during hunts, giving you a tactical advantage to gather evidence and confirm the ghost’s identity. Practicing this technique in offline mode first can help you get comfortable with the timing and positioning before trying it in a live game. I've personally found that mastering this approach improves both survival chances and the accuracy of ghost identification during investigations. Remember, staying calm and patient is key. Move deliberately and watch the ghost’s reaction to your movement cues. Using this informed hiding technique not only enhances your gameplay but also adds a strategic layer to your ghost-hunting adventures in Phasmophobia.
