Ancestral Worship allows you to sacrifice items of your ancestor's desires to an Ancestral Shrine. This gives you numen points that can be used to pray for various things. To sacrifice an item, left-click it to hold it in your hand, and then right-click the ancestral shrine.
"Construct an Ancestral Shrine. As soon as you construct a shrine you will receive a quest -- For the Ancestors! -- asking you to sacrifice either one of three items. Sacrificing the primary item -- marked with a gold frame -- will net you one point of Numen, provided that the item sacrificed is of equal or higher quality to the number of Numen points you already have, and sacrificing either of the secondary items -- marked with a silver frame -- will give you a new set of sacrificial requests at no penalty, provided, again, that the item sacrificed is of equal or higher quality than the number of Numen points you already have. If you sacrifice any item of lower quality than the number of Numen points you already have, you will lose one Numen point, but receive a new set of sacrificial requests." ~Jorb
" Characters without actual ancestors can still use the system, and all count as stemming from a long and distinguished line of sprucecap noobs/freshly spawned alts, with 10 in every Attribute, and 1 in every Abilit" ~jorb
- A shrine can be only be used by the hearthling who built it.
You get a new Prayer menu when you get enough numen for a prayer and the prayer is applicable to the character.
"For the ancestors!"
Ancestral Worship allows your character to gain numen points by sacrificing to his ancestors. You can see your ancestors' desires in the "Worship" submenu of your character sheet. Numen points can be used for various effects, all lending you some of the strength of your predecessors.
