Old Mission

Old mission is a broken down, but still functional church. Outside you can find a tuna cactus (requires Foragin' 2).

Inside
Inside the church are various nuns, pews, and other church decor. You can find Sister Mary (on the left), who will tell you the 3 Holy Relics were stolen, and gives you permission to go into the catacombs to retrieve them. After retrieving all the Holy Relics, Sister Mary will reward you with a class-specific item:
 * silk nun's boots (Snake Oiler)
 * br*** censer (Beanslinger)
 * kneeling pants (Cow Puncher)

Note that touching the pulpit while cowrrupted will give you the (negative) effect Divine Disapproval.

Catacombs 1
The first level of the catacombs contains a number of skeletal combats:
 * 5 spooky floating skulls are in the pile of skulls to the right of the first coffin in the catacombs
 * 1 spooky floating skull is in the second alcove
 * A skeleton with 2 skulls guards access to the deeper level of the catacombs

Among the various skulls and alcoves you can also find a few items
 * A gold tooth in the first skull
 * A souvenir spoon in the third skull
 * A creepy whispering stone in the cemented pile of skulls (requires pickaxe)
 * The perk it provides will allow you to gain XP from the fourth skull, and  XP from the agitated pile of bones at the entrance to the deeper catacombs (avoiding the fight with the skeleton with 2 skulls).

If you have the skull with an odd tag on it, you can put it into the fifth alcove, giving you 10xp.

Catacombs 2
In the lower level of the catacombs you have will find 3 boss fights, each providing one of the missing relics.
 * Saint Beefus is in the first chamber. You will need to pry open his sarcophagus (requires 10 Muscle, or just 8 Muscle with a crowbar).
 * You get the relic, St. Beefus' finger, as well as a decent weapon, St. Beefus' thigh.
 * Santa Cortada is in the second chamber (consisting of Santa Cortada's skull, Santa Cortada's right armbone, Santa Cortada's rib cage, Santa Cortada's left armbone, Santa Cortada's right legbone, Santa Cortada's pelvis, Santa Cortada's left legbone). Either a Mysticality of at least 10 or the Anatomical Learnin' perk is necessary in order to try and reassemble the bones (which then fails and initiates the fight).
 * You get the relic, Santa Cortada's skull as well as Santa Cortada's ring.
 * Saint Pope is in the third chamber. A Moxie of at least 10 is required to insult him and make him angry enough to fight.
 * You get the relic, pope's pelvis, as well as the fake Pope hat

A clue for the Necromancer Journal can be found by investigating the trash in the right corner.
