Made vulnerable and spawn code not depend on the enemy type. Hopefully nothing broke.

 Attacks can be "hunter" or "patrol". The "patrol" option does not use the "turn_threshold" option. The "turn_threshold" option is how quickly the hunting enemy will turn around to attack the player. Hunters will leave their area to pursue the player once he has entered the enemy's range.
 
 
+#### Special Enemy Behaviors
+
+Enemies can have special behaviors regardless of their type. Here are some examples:
+
+##### incorporeal Goblin
+
+``` json
+{
+    "x_range": [400, 415],
+    "y": 0,
+    "enemy_type": "goblin",
+    "health": 30,
+    "damage": 2,
+    "attack_range": 1,
+    "has_vulnerability": true,
+    "is_vulnerable": false,
+    "vulnerability_duration": 1000,
+    "invulnerability_duration": 5000,
+    "speed_multiplier": 0.8,
+    "attack_cooldown": 1200,
+    "attack_pattern": {
+        "type": "hunter",
+        "turn_threshold": 2
+    }
+}
+```
+
+##### Spawning Other Enemies (like revenants)
+
+You can mix and match these behaviors. For an example of a witch who spawns black cats, see "Wicked Quest/13.json"
+
+
+## Sound Requirements for Special Behaviors
+
+When adding special behaviors to enemies, you'll need corresponding sound files:
+
+For vulnerability system:
+- enemy_is_vulnerable.ogg - Sound when enemy becomes vulnerable
+
+For spawning behavior:
+- enemy_spawn.ogg (optional) - Sound when spawning new enemies
+
+## Tips for Custom Enemies
+
+- Balance special behaviors carefully
+- Test enemy combinations thoroughly
+- Consider providing audio cues for special behaviors
+- Remember faster enemies should generally do less damage
+- Vulnerability systems work best with higher health values
+- Spawning enemies should have lower health to compensate
+
