Each part of a giant adversary has it's own Heart Total and must be specifically targeted, this is called a Strike Point.
Destroying a body part removes a monster ability.
Moving from part to part is subject to same rules as moving through a regular Battlefield Area.
URARANI
The forgotten crystal beast
Creatures from the 1st Aeon do not follow the rules of other eras. They run the gamut from messengers with gossamer wings to killing machines made of unbreakable glass. Most have been destroyed or withered away in a reality they find suffocating, but others have found ways to remain.
Urarani is an enormous, arachnid creature made of murky chitin. It was once part of an Unshaped’s tale but abandoned when it was deemed unappealing by its creator. Its appearances in the Outer World almost always include a rampage of some kind, so it is fortunate that it remains a rare sight.
I am looking forward to Rey's Monsterhunter/Shadow of the Colossus inspired adventure/monster book!
Rey's original concept...
