The Hoard Mechanic: (To provide the confusing nature of Xorvintaal I'll probably have a different mechanic called the Horde mechanic.. heh.)
- "Treasure" is a category of object that includes any object that can be sold for 100% of its cost normally. This includes coins, blocks of precious metals, gems, or other trade goods such as cows, if that's what you want.
-- Normally means that feats and PrCs which allow the sale of other items for 100% do not let an item be considered treasure.
-- Items created directly from a magic spell can not be considered treasure. Eg: Wall of Iron, Flesh to Salt.
-- For streamlining purposes, all treasure is considered to weigh 1lb for every 10gp worth.
- A "Hoard" is a designated area which can be attuned to any of the player-dragons.
-- Hordes come in sizes, named after the hebrew alphabet. The smallest is Yod, followed by Teth, Heth, Zayin, Waw, He, Daleth, Gimel, Beth, and the largest, Aleph.
--- The younger dragons, with no respect for tradition, also refer to these Class N Hordes, with Class 1 being the smallest and Class 10 being the largest.
-- The purpose of a hoard is to generate income, at the start of every round manned horde earns 5% interest on the value of all treasure within it, to a maximum based on hoard size. This limit is size-numberx100.
--- A manned hoard is a hoard with its CR in exarchs affiliated with the same dragon sharing its space.
-- Hoards larger than He(, not including He itself,) can also attract exarchs, the horde level determines the maximum level available, which is size-number minus five.
-- The dragon's home lair counts as a hoard of size Daleth (6), except for the limit on maximum exarch level, which is increased by 1/3rd the dragon's CR.
--- Only the dragon can man its lair-hoard.
-- To seize control of a hoard, its space must contain exarchs of only one player-dragon during the start of round. You do not lose control unless another dragon seizes control of it, thus you may abandon a hoard and still retain control of it, etc.
(Yes, the hebrew names are just to confuse people)
