Irridesiums are able to use magic items as sorcerers, including devices and enchantments. At least two dragons have had enchanted symbols inlaid into their horns for use as magical items. An irridesium dragon has two breath weapons. The first is a cone of cold fire. This flame causes cold damage and yet sets flammable or combustible items on fire.
Cold resistance protects normally, but fire resistance has no effect.
The second breath weapon is a cone of shimmering confusion gas. Thus, their sorcerer class level might be very high. The existing irridesiums are 19 th level sorcerers, with additional spells known and metamagic feats. The dragon's every word causes subjects to save vs. Will or act as if affected by a symbol of persuasion . They are interested in conversation, stories, and news of the kingdoms of man- and kzinkind.
