Yes to reducing damage and DR. Let's drop Imp Bull Rush and either Cleave or Combat Reflexes.
Storm giants are gentle and reclusive. They are usually tolerant of others but can be very dangerous when angry.
They live quiet, reflective lives and spend their time musing about the world, composing and playing music, and tilling their land or gathering food.
I suppose they could arise from starvation brought on by the destruction of their nearby environment. Maybe temperaments are the unliving embodiments of eco-terrorism?Storm giants live in castles built on mountain peaks or underwater. They live off the land in the immediate vicinity of their lairs. If the natural harvest is not enough to sustain them, they create and carefully till large gardens, fields, and vineyards. They do not keep animals for food, preferring to hunt.
