Using special abyssite stones, monsters called "Voidwalkers" may be summoned from the parallel world of Abyssea. These monsters are an integral part of the Trial of the Magians for the creation of Empyrean Weapons.
When you have any of the abyssite key items, resting with /heal will check whether there are any Voidwalker NMs alive anywhere in the zone:
The message "The abyssite quivers ever so slightly, but emits no light" means that there are no Voidwalkers currently alive in this zone that you are currently able to spawn.
The message "The abyssite quivers ever so slightly and emits a faint light" means that there is at least one Voidwalker alive in the zone that you are currently able to spawn.
Since you can carry multiple tiers of abyssite simultaneously - for example, a clear abyssite, a colorful abyssite, and a purple abyssite - this message alone does not tell you what you're detecting. For that, you must be enough to get a "beam of light". See the table below.
If you get no message at all when you /heal, you're in a zone that has no Voidwalkers.
Relevant zones are shown in the big infographic below.
If there is a Voidwalker reasonably close to you (within 300 yalms of your current position), you will receive a message indicating the distance and closest compass direction to the VWNM.
The strength of the "beam of light" emitted by the abyssite indicates the tier of VWNM detected. See the table below.
If you have two or more applicable abyssites and there are two or more nearby spawnable VWNMs, it will (usually ) report the nearest, regardless of tier.
If you /heal within ~5 yalms of the Voidwalker's current location, it will spawn and attack you.
They move more quickly than players, and /healing takes time, so it may take several attempts.
The VWNM spawns claimed to the player that popped it.
If it is a tier 3+ VWNM, that player is also the only one who loses their abyssite when the VWNM spawns.
Each tier of Voidwalker has a different message for its abyssite resonance:
Tier
Type
Abyssite Message
Respawn Time
1
"Small Fry"
feebly
Within Minutes
2
NM
softly
60 Minutes
3
"Shadow"/"True" HNM
solidly
120+ Minutes
4
Yilbegan
strongly
120+ Minutes, likely 8+ Hours. Exact time unknown
Tier 3 and 4 VWNMs have two different versions that can spawn, often referred to as "Shadow" and "True". The "True" versions grant a title and drop rings, while the "Shadow" versions do not.
These names come from the only visible difference between the two: "True" VWNMs cast a shadow, while the "Shadow" version has an otherwise identical model and animations but casts no shadow.
Make sure you have "High" shadows enabled in your game settings (under Config -> Misc. settings) to be able to see the shadow! If this setting is enabled and the monster does not cast a shadow, it is not "True".
Upon defeating a VWNM, there is a chance that your abyssite will upgrade to the next tier of abyssite:
When you defeat a tier 1, there is a low chance that your clear abyssite will upgrade into a colorful abyssite if you don't already have one.
When you defeat a tier 2, there is a medium chance that your colorful abyssite will upgrade into a tier 3 abyssite, depending on the zone you're currently in:
If you have the tier 3 abyssite for the zone you're currently in, you can't upgrade the colorful abyssite. (This is good if you're doing a tier 2 VWNM Magian Trial - you won't have to farm another colorful abyssite!)
Spawning a tier 3 will immediately destroy your tier 3 abyssite!
However, killing a tier 3 (whether Shadow or True) has a high chance to drop a black abyssite if you don't already have one.
