You prepare the dead for the perfect animation.

You can alter the hd of a corpse in lieu to animate a more or less powerful creature. The maximum hd change is +- 3. In before you have to do some preparations, if one fails you can 'clean' the corpse with a DC 15 profession(cleaner) check, 1 day per check. To augment an undead you must cover it in silver (10 sp) and a craft(arts work) check DC 15. To corrupt an undead you must cover it in a mixture of ash and black oil (10 sp) and a craft(alchemy) check DC 15. During the preliminaries failing does not damage the opal.

Focus: A black opal which will be used to animate the dead afterwards.

Backlash: None

Material Component: see below

Failure: When two checks during the whole ritual fail, the opal gains a strain and its value decreases by 10%.
