Eclipse

Eclipse Empowered (Su) When an eclipse giant is in the presence of and can see either a solar or a lunar eclipse, they’re affected by greater resistant armor for as long as the eclipse lasts or until the giant can no longer see the eclipse, whichever comes first. Upon first being affected by greater resistant armor, the eclipse giant can choose to be protected against all kinetic damage or four types of energy damage; the giant can’t alter this choice.
Infuse Debris (Su) As a move action, an eclipse giant infuses the next bit of debris they hurl with healing or destructive energies. If they choose healing energy, the difficult terrain the debris creates is infused with healing energy for 1 minute; a creature that ends its turn in that area heals an amount of Hit Points equal to the giant’s CR. If the giant chooses destructive energy, their next hurled debris attack is made against EAC and deals additional force damage equal to the eclipse giant’s CR on a hit.

Eclipse giants are known to wander worlds with little care, and during an eclipse, a hidden “inner self” takes control, often changing the giant’s personality and approach to life.

About the giant family (Alien Archive 2, p. 62):

Giants are humanoid creatures with great strength and mighty stature, standing from 9 feet to over 25 feet tall. They often live apart from other races, as even space stations intended to be inclusive of multiple species are often too small to comfortably accommodate a giant’s massive size. How welcoming these giants are to non-giant visitors depends on the specific giant society, though all giants can be unpredictable and dangerous to others.
