Creature Shards
When you sacrifice a creature you will now receive shards based on the species of that creature. These shards can be used to enhance other creatures and give them unique abilities. The shards are partially recovered when sacrificing a creature with these new abilities. Creature age, transfer count, rarity, level and tokens, all these greatly influence the number of shards you will get for one creature. Young creatures get no shards, while old and upgraded crits can get a lot of shards for their species. Additional details can be checked by clicking the shards tab on the sacrificing detail page in the altar. Its not easy, but its possible to reverse engineer the reward formula, so you can determine what things can double or tripple your shards reward.

Work in progress! Sacrificing and getting shards is complete and formulas are unlikely to change, you can use altars. However, the use of shards is still work in progress. Before I enable that, i need to finish all the associated abilities.
Enjoy :)
