Thaye

Ability: aging

The Thaye has an internal “age” that controls how much it does:

• It tries to age for the first time 1 minute after an exit door is opened.
• If at least one player is in the same room as it or within 3 m, it adds 1 to its age and tries again in 1 to 2 minutes. If nobody is there, it tries again in 30 s.
• If it ages during a hunt, the change takes effect when the hunt ends.

Age	Hunt sanity threshold	Activity	Hunt speed
0 (start)	75%	200%	2.75 m/s
1	69%	185%	2.575 m/s
2	63%	170%	2.4 m/s
3	57%	155%	2.225 m/s
4	51%	140%	2.05 m/s
5	45%	125%	1.875 m/s
6	39%	110%	1.7 m/s
7	33%	95%	1.525 m/s
8	27%	80%	1.35 m/s
9	21%	65%	1.175 m/s
10 or more	15%	50%	1 m/s

Due to a development oversight, each threshold is actually 1% lower than the one in the table.

Each time it ages, the “human” age the Ouija Board gives goes up by 1 to 4 years, with no limit you could realistically reach. Like any ghost, it starts with a human age between 10 and 90.

Activity

• When it tries to do a ghost event, it succeeds with a probability of (1 − age ÷ 9). After aging 9 times it can no longer do ghost events, unless you force them with cursed possessions.
• It interacts with doors a bit more than most ghosts: a 30% chance instead of the standard 25%.

Hunt

• It doesn’t get more likely to hunt as sanity drops: below its threshold, every time it leaves its idle state it always has a 1/8 chance of starting a hunt.
• It doesn’t speed up with line of sight.

Strategy

• Early on it interacts and does ghost events very often, so it’s usually easy to find. But if you take a while to locate it (especially on large maps), it can be one of the most dangerous ghosts: its starting threshold is higher than the Demon’s and it’s very fast during those first hunts. Find your hiding spots as soon as you can.
• Use that early activity to complete the non-hunt objectives and take photos. If you’re careful about how you interact with it, a (near-)perfect investigation is easy to pull off. If you spend too much time in the ghost room, it ages fast and, without cursed possessions to make up for it, getting objectives and photos becomes a chore.
• Leave the hunt-related objectives for when it’s no longer a threat: after aging 4 times it’s slower than your average sprinting speed, and after 7 times, slower than your walking speed, so you can loop it with no trouble. A safe way to do it is to stay in the ghost room until it ages and then force a hunt with a cursed possession.

How to identify it

• Don’t mistake it for the Obambo, which has two very different speeds and thresholds depending on its state; the two also share two pieces of evidence.
• If it’s fast at first, gets slower from one hunt to the next as you spend time near it, and doesn’t speed up with line of sight, it’s probably a Thaye. The Obambo does speed up with line of sight and can change speed mid-hunt: that’s how you tell them apart.
• If it hunts early and is very active, but over time it hunts, interacts, and does ghost events less and less, that also points to the Thaye.

Trivia

• Thaye (pronounced “thuh-yeh”), also called sarai or tasei in Burmese (သရဲ), are disembodied spirits from Myanmar folklore that have many forms at once, depending on who’s looking at them. They appear in the dead of night and cause minor nuisances.
• When the Mimic mimics a Thaye, it picks a random age.
