Description
8 p.m. - 6 a.m. Game Time Spawn
At 8 p.m. game time, all wandering undead in the lesser Faydark immediately respawn with a chance of being a rancorous ghast. Any undead killed at night then have a chance to spawn as a ghast at the normal zone respawn interval. At 6:00 a.m. game time the undead once again respawn as only skeletons and mummies.
The heart is a semi-rare drop, so expect to stay multiple game nights to collect all 4. Maybe about 25% drop chance for the hearts.
Tracking Strategy
Pro tip: bring a tracker to know when a ghast is up. If there isnt one up, just track down and kill the wandering skeletons and more ghasts will spawn. In one night cycle I was able to get 4-5 ghasts to spawn with this method. Being in wolf form will make you non-KOS to the roaming, ill-tempered brownies.
Sense the Dead Strategy
Clerics can use the level 9 spell Sense the Dead to find the closest undead. While this spell finds any undead, not just the ghasts, this can actually be helpful, as it will also point you toward placeholders. If you cast the spell near the areas marked in red on the map, you shouldn't end up killing too many unecessary undeaded.
Plus, as a bonus, this approach can help raise your Divination skill, since the spell is cheap and cast repeatedly.
