One of my players has the Alert feat, according to which:
[…] You can’t be surprised while you are conscious.
Now, does this mean that a hidden enemy is automatically spotted?
Let me provide a practical example. The party is walking along a path. The PC that has the Alert feat is in the middle of the line. A group of enemies is hidden 30 meters ahead. When the PCs pass by, they attack. Is the first turn of the battle handled as a normal turn? If the enemies are automatically spotted, when are they spotted?
