Spirit prayer pig

A Spirit prayer pig is a prayer-restoring familiar that can be created in the machine under Eli's farm, after completion of the Bringing Home the Bacon quest. The familiar comes in three tiers. Each tier increases the usefulness of the pouch. To increase the tier of the pigs, one must upgrade the machine in the storm cellar. Each tier uses the same pouch. Upgrading the machine after obtaining a pouch still summons the higher-tiered familiar.

Tier 2 requires level 44 in: Summoning, Construction and Crafting as well as 3 Oak Planks, 2 Steel Bars and 3 Nails of any type.

Tier 3 requires level 84 in: Summoning, Construction and Crafting as well as 3 Teak Planks, 2 Mithril Bars and 3 Nails of any type.

These requirements are NOT boostable.

Prayer pigs have a right-click option "Restore prayer", which restores some of the player's prayer points from those stored in the pig. The pig starts out with a certain number of points, depending on the tier. Once the points are drained, it will regenerate points every 120 seconds until it reaches its initial points again. For the tier 3 pig, the maximum prayer points that can be restored will be 840 + 27 * 210 = 6510.

Prayer pig pouch
A prayer pig pouch is used in the Summoning skill to summon a prayer pig. It is made by using a Summoning pouch on the Prayer pig machine with 6 spirit shards, a gold charm and a prayer pig tooth in your inventory. It gives 15.6 Summoning experience when made. Using this pouch on a Summoning obelisk will enable a player to create 10 Bacon blast scrolls.
