Lore & Background

Storm giants are the most powerful and majestic of all giantkind, dwelling in cloud castles high above mountain peaks or in underwater palaces beneath tempestuous seas. These noble beings embody the raw power of weather and storm, commanding lightning, wind, and rain with the same ease that others might gesture with their hands. Their society values wisdom, honor, and the responsible use of tremendous power, making them natural leaders among giant communities and respected figures in the cosmic order.

Living in harmony with the elemental forces of air and water, storm giants spend their time in contemplation of cosmic mysteries, artistic pursuits, and the guidance of lesser beings. They view themselves as stewards of the natural world's most powerful forces, using their abilities to maintain weather patterns and protect important locations from both natural disasters and malevolent forces. Their long lifespans allow them to take a perspective that spans centuries, making them valuable sources of historical knowledge and wisdom.

Combat Tactics

Storm giants are devastating combatants who control the battlefield through weather manipulation and lightning attacks. They prefer to fight at range, using their ability to call down lightning bolts while summoning wind and rain to hamper enemy movement and visibility. Their mastery over storm magic allows them to create environmental hazards that persist throughout combat.

In battle, storm giants use their flight capabilities and weather control to maintain tactical superiority while raining destruction down on enemies from above. They can create localized storms that provide cover for allies while hindering enemies, and their legendary actions allow them to maintain constant pressure through repeated lightning strikes. When forced into melee combat, their enormous size and strength make them formidable opponents.
