Fecas are born protectors. When a friend has entrusted them with something, you'll never get it off them - not even over their dead body! They'll fight tirelessly to keep their allies safe. Oh, and you should think twice before picking off any stray Gobballs: Fecas may not be shepherds any more, but it's still in their nature to stand guard over any vulnerable creature targeted by a vicious attacker...
This spell significantly increases the targeted ally's defenses. However, it becomes more and more costly based on the number of allies targeted by this spell within the same turn.
