Ghast

Ghasts are lingering souls of people that starved to death in Mort Myre Swamp. When they first appear they are invisible and have no combat level, and try to turn food into useless rotten food; if players have no food they will do damage instead. Upon completion of the easy Morytania Diary, ghasts will have a 50% chance of ignoring the player rather than attacking. Building the fire of dehumidification in the area stops these attacks (requires the completion of Making Friends with My Arm).

When deciding to attack a player, ghasts have a 7/10 chance of completely missing them. In the remaining 3/10 of cases, the ghast will perform a rot attack if food is present in the player's inventory, or deal 1-3 points of damage if not.^[1] Regardless of the outcome, the ghast will then retreat several game squares before re-targeting the player.

Ghasts can only be killed after completion of the Nature Spirit quest. You must have a filled druid pouch to kill them. You must use the ability of the blessed silver sickle near some dead logs or bushes to harvest Mort myre fungi, stems, or pears then put those into a druid pouch by filling it. When your druid pouch has been filled, you can use it to make a ghast visible, or wait until a ghast attacks you to make it visible. This renders the ghast vulnerable to attack; killing it rewards the player with 30 Prayer experience. Higher level ghasts reward more Prayer experience upon death.

The salve amulet's bonuses do not work on the ghasts, nor can Crumble Undead be used on them.

Ghasts are notorious for their ability to rot food in the player's backpack. This includes food held in containers, such as baskets or sacks, turning the whole container into one rotten food. They can also rot certain items that cannot be directly eaten, like pineapples or coconuts.

Ghasts cannot rot:

• Most alcoholic drinks, including bottle of wine, moonlight mead, beer, poison chalice, or gnome cocktails like premade blurb' sp.
• Raw food that cannot be directly eaten
• Healing potions, like Saradomin brews, Guthix rests, or barbarian mixes

Due to the nature of making the ghasts visible, they are not good for combat training. They do drop lots of herbs. The material drops are pretty weak as well. You do, however, gain reasonable Prayer experience as well as combat experience for killing them.

The best place to hunt them would be just west of the Nature Grotto from the Nature Spirit quest. This allows you to keep refreshing your Prayer points without using valuable Prayer potions. A player can use whichever weapon they choose for combat, a silver sickle is not needed to kill them. Fully charge your prayer points, go west of the grotto (where the ghasts are) and cast Bloom with the sickle next to the rotten logs. Try and do it between 2 logs, and you will occasionally get 2 mushrooms to put in the druid pouch. Do this over and over until you are out of prayer points. Now "use" the filled pouch on the ghostly ghasts - do not wait for them to attack you. Often they will just float around, or the pouch will activate itself, allowing the solid ghast to float out over the water where it cannot be attacked. The drops will more often than not fall under the rotten logs, so search the ground carefully after defeating the ghast.

Prayer experience is granted to whichever player gets kill credit for the ghast, meaning ghasts spawned by another account's druid pouch can be killed for Prayer experience. However, if the player is more than 3 tiles away from a ghast as it dies, the Prayer experience will not be granted.

Drop rates are estimated based on 35,328 samples from the Drop Rate Project, unless otherwise cited.

The average Ghast kill is worth 340.97.
