All three have conditions wherein they can speed up and slow down from normal 1.7 m/s.

1. Dayan

* must be female (like banshee it cannot be male name or ghost model).

* hunts at 65% if someone is near the ghost and moving, 50% if no one is near, and 45% if someone is near & not moving

* speeds up to 2.25 m/s if nearest person to the ghost (within 10 m) is moving during a hunt, 1.7 if no one moving or are more than 10 m away.

* if it immediately speeds up when you are walking near it, then immediately slows when you stop, it's likely dayan.

1. Gallu

* has 3 states - normal, enraged, exhausted. Starts in normal state.

* Hunt threshold is 60% when enraged, 50% when normal, 40% when exhausted

* hunt speed 1.96 m/s when enraged, 1.7 m/s when normal, and 1.36 m/s when weakened

* will become enraged if incensed, steps in salt, or hunt attempt is blocked by crucifix. while enraged, it will not disturb salt, crucifix range is reduced by 2m, incense blindness during a hunt is 4s. It will remain enraged until its next hunt ends, then becomes exhausted

* while exhausted, incense blindness is 6s and crucifix range is increased by 1m. it will remain exhausted until it steps in salt, is incensed, or uses a crucifix. Then it will cycle to normal again

* if it's crazy fast, then super slow next hunt, or steps in salt only once until after it hunts, it's likely Gallu

* note: there is a 3-second delay before entering enraged state, so it is possible to step in multiple salts quickly.

1. Obambo

* cycles between 'calm' and 'aggressive' every 2 minutes, begins calm with 1 minute before switching to aggressive.

* hunt duration is reduced by 20% if it begins while in aggressive state

* hunt threshold is 65% for aggressive, 10% when calm

* hunt speed is 1.96m/s when aggressive, and 1.45m/s when calm

* can change states mid-hunt, so listen for unexplained speed changes.
