Ghast

Ghasts are undead souls of people that starved to death in Mort Myre swamp. When first encountered, they are almost transparent, have no combat level, and try to turn food into useless rotten food. If a player has a container of food, such as a hamper, and the ghast is successful, the container and its contents will become rotten. If a player has no food, they deal damage instead.

A player can kill a ghast only after obtaining a Druid pouch from the Nature Spirit quest. A player must charge it with the Cast Bloom ability (uses up to six prayer points per cast) of a blessed Silver sickle or the Ivandis flail near some dead logs, branches, or bushes to harvest Mort myre fungi, Mort myre stems, or Mort myre pears. Then put three or more of those harvested items into the druid pouch by filling it. A player may fill it multiple times in a row to contain many charges.

It is more convenient to use an Ouroboros pouch obtained from the Temple Trekking activity, which has similar functions but with infinite charges.

If a Ghast attacks a player with a charged pouch (or a player uses a charged pouch on a Ghast), the Ghast becomes visible and one charge is consumed. In this way, a charged pouch protects a player's food from being rotten. Visibility renders the ghast vulnerable to attack. Killing it rewards the player with Prayer experience equal to the combat level of ghast (e.g., 30 Prayer experience for a Level 30 ghast). Killing higher level ghasts from the Temple Trekking activity rewards the player with up to 139 prayer experience per kill.

Ghast Hunting Notes
Although not difficult, it is considered by some to be rather tedious to summon Ghasts for combat training. They do drop lots of herbs, much more so than Hobgoblins. The material drops are rather petty. 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. The Silver Sickle does not have to actually equipped to gain its benefits, it just has to be in your inventory. However, you must also have a filled druid pouch in your inventory to prevent your food from being rotted. A player can use whichever weapon they choose for combat, not having to use the Sickle. 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 as many logs, branches, and bushes as possible, and you will often get several blossomed items 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.

Transformation
Ghasts are in fact humans, transformed into these horrible creatures due to a lack of food, as proved by Temple Trekking. This also explains why ghasts attempt to steal and consume food from players. When one is in the Morytanian environment and does not eat enough, the following will occur:


 * 1) At first the human looks hungry, but normal.
 * 2) Then the hair colour will begin to fade. The victim's skin is turning to a purple-adjacent colour.
 * 3) Nextly, the hair will become completely grey and might fall out or grow even more, the cheeks and nose begin to "slump" and the skin turns to a more brown colour. The white of the eye will become slightly yellow.
 * 4) If the person still hasn't eaten, their skin turns blue-grey and completely loses elasticity. The white of the eye is now completely yellow.
 * 5) Finally, the victim turns into a ghast, at which point they can no longer be cured.

Trivia

 * If a Ghast dies above water, there will be no drop at all.
 * The level 30 Ghasts attack at the speed of a whip, but their higher levelled counterparts encountered during Temple trekking attack much slower (same speed as an ogre bow).
 * The Temple Trekking ghasts seem to have blueish eyes. In addition, they are more translucent than the ones in the swamp.
 * If you finished Deadliest Catch you have access to a bank deposit box somewhat north-west from the grotto where you can bank your herbs and other drops.
 * Since their graphical update on 17 August 2011 the ghasts now have same moving, idle and death animations as the aberrant spectres.
 * When a Ghast dies, its spirit resembles the way it used to look before their graphical update.
 * Since the update to Temple Trekking on 17 August 2011, the Ghasts in the events no longer give prayer xp.
