Magmalings are impish creatures of elemental fire and rock, who take joy in burning and seek to ignite all the world in one enormous conflagration.
Magmalings are short, humanoid creatures who stand about four or five feet tall. They are composed of molten rock, and are completely immune to fire. When a magmaling is killed, it releases the elemental energy inside it and explodes, spraying burning shrapnel over a wide radius.
Sevastiaran summoned several magmalings to “test” the party’s skill, but they quickly got out of hand and began to burn the party’s carriage. Sev then helped the party to defeat them.
