Sky Archdragon

The sky archdragon is wrought of living metal and crackling storm, a wyrm of crystalline scales whose breath comes as forked lightning. It rides the high winds far above the world, descending only to scatter its enemies with thunder.

It gains a +2 status bonus to all saves vs. magic.

• Countered by Fire If the sky dragon takes fire damage, the elemental magic of metal within them is tempered. Until the end of their next turn, they take a –1 circumstance penalty to attack rolls and AC, and their jaws Strikes don't deal electricity damage. This limitation ends if the dragon uses Steel Lightning Breath.
• Fed by Earth (divine) When a sky dragon is targeted by an earth spell or effect, they crystallize the minerals in their scales to create a light-bending or light-scattering layer for camouflage. For 1 minute, the dragon is concealed while flying.
