Osteomancy [Osteo]

Osteomancy

General Rules
Osteoblast Level: The hit dice of the creature from which the bone (see Attuning and Casting an Ossein below) comes determines one half of the osteoblast level of the effect. The other half comes from the wielder of the bone. Thus, the total osteoblast level is one half of the wielder's class level, plus any special modifiers, and one half of the hit dice of the bone or organ. Add these two factors together before rounding down.
Ossein DC: The roll to save against an ossein is 10 + the ossein level + the osteogen's wisdom modifier.
Ossein Pool: This determines the number of ossein points that the osteogen has available on any given day. The amount of ossein points that the osteogen can expend on a single ossein is capped by his osteoblast level. The table of points is provided below, labelled Table 1.
Ossein Cost: An ossein costs a number of points equal to the level of the ossein * 2, and then reduced by 1. Thus, costs scale from 1 point for a first level ossein to 17 points for a ninth level ossein.

Attuning and Casting an Ossein
Bone Hit Dice: The hit dice of a bone is equal to the one half the hit dice of the creature from which it was taken, and partially determines the power of the ossein that is cast through it.
Harvesting: A bone or organ must be harvested in a special way for it to be used in osteomancy. Otherwise, it is simply scavenging from the dead. This requires a ritual dismembering of a deceased creature, followed by annointing the chosen bone or organ with preservative unguents. Harvesting a bone in this way costs 50 gold in supplies and ointments, and takes one half hour per bone or organ. The osteogen may only harvest one bone or organ from a single creature, as he focuses all of the energy from that creature into the bone grasped in his hand. Under all but the most strained of circumstances, this process is immediately followed by attuning the bone or organ (attuning is described below), but when time is of the essence, it is possible to harvest the bone and store it for later attuning. However, a bone must be attuned within one week of its harvesting, otherwise it no longer retains the magical essence. If the creature from which the bone or organ is ever raised, the bone or organ stops functioning immediately.
Attuning: Each piece of bone is attuned to a single ossein, and from then on can only be used to cast that ossein. The osteogen can only attune osseins with a ossein level equal to his osteoblast level times two minus one (minimum one), ignoring any bonuses to osteoblast level. The osteogen must perform a one hour ritual that requires the expenditure of gold pieces equal to 10 times the ossein level in inlays, unguents and engravings. Once the osteogen has attuned a bone, he may use it to cast the chosen ossein. A bone or organ may not be re-attuned, and only works for the creator of the bone or organ.
Casting: In order to cast an ossein, the osteogen must have the bone or organ equipped in one hand. He may draw, equip, or unequip bones and organs as a free action. If an enemy attempts to sunder (or likwise) a bone or organ while held, treat it as a wand. For all purposes, treat the ossein as if it had been cast by a wizard (or appropriate class), with a caster level equal to the osteogen's osteoblast level.

Bonus Ossein Points: The osteogen gains bonus ossein points for having a high casting statistic. He gains bonus ossein points equal to his wisdom modifier times his osteogen level times 1/2.

Bones and Organs
These gruesome tools are the core of osteomancy. Each holds powers over a certain area of the body of magic, and assists the osteogen in casting osseins that channel that aspect of magic. Waving and gesticulating with them, the osteogen summons up the power necessary to wield his magic.
